Full textDoctor of Philosophy
The modern power grid, known as the smart grid, is transforming how electricity is generated, transmitted and distributed across the US. In a legacy power grid, the utilities are the suppliers and the residential or commercial buildings are the consumers of electricity. However, the smart grid considers these buildings as active grid elements which can contribute to the economic, stable and resilient operation of an electric grid. Demand Response (DR) is a grid application that reduces electrical power consumption during peak demand periods. The objective of DR application is to reduce stress conditions of the electric grid. The current DR practice is to shut down pre-selected electrical equipment i.e., HVAC, lights during peak demand periods. However, this approach is static, pre-fixed and does not consider any consumer preference. The proposed framework in this dissertation transforms the DR application from a look-up-based function to a dynamic context-aware solution. The proposed dynamic demand response framework performs three major functionalities: electrical load forecasting, electrical load disaggregation and peak load reduction. The electrical load forecasting quantifies building-level power consumption that needs to be curtailed during the DR periods. The electrical load disaggregation quantifies demand flexibility through equipment-level power consumption disaggregation. The peak load reduction methodology provides actionable intelligence that can be utilized to reduce the peak demand during DR periods. The work leverages functionalities of a deep learning algorithm to increase forecasting accuracy. An interoperable and scalable software implementation is presented to allow integration of the framework with existing energy management systems.

Full textIn recent years, significant advances made in deep neural networks enabled the creation of groundbreaking technologies such as self-driving cars and voice-enabled personal assistants. Almost all successes of deep neural networks are about prediction, whereas the initial breakthroughs came from generative models. Today, although we have very powerful deep generative modeling techniques, these techniques are essentially being used for prediction or for generating known objects (i.e., good quality images of known classes): any generated object that is a priori unknown is considered as a failure mode (Salimans et al., 2016) or as spurious (Bengio et al., 2013b). In other words, when prediction seems to be the only possible objective, novelty is seen as an error that researchers have been trying hard to eliminate. This thesis defends the point of view that, instead of trying to eliminate these novelties, we should study them and the generative potential of deep nets to create useful novelty, especially given the economic and societal importance of creating new objects in contemporary societies. The thesis sets out to study novelty generation in relationship with data-driven knowledge models produced by deep generative neural networks. Our first key contribution is the clarification of the importance of representations and their impact on the kind of novelties that can be generated: a key consequence is that a creative agent might need to rerepresent known objects to access various kinds of novelty. We then demonstrate that traditional objective functions of statistical learning theory, such as maximum likelihood, are not necessarily the best theoretical framework for studying novelty generation. We propose several other alternatives at the conceptual level. A second key result is the confirmation that current models, with traditional objective functions, can indeed generate unknown objects. This also shows that even though objectives like maximum likelihood are designed to eliminate novelty, practical implementations do generate novelty. Through a series of experiments, we study the behavior of these models and the novelty they generate. In particular, we propose a new task setup and metrics for selecting good generative models. Finally, the thesis concludes with a series of experiments clarifying the characteristics of models that can exhibit novelty. Experiments show that sparsity, noise level, and restricting the capacity of the net eliminates novelty and that models that are better at recognizing novelty are also good at generating novelty

We have developed a framework for Analyzing Facial Videos and applying it to Automatic Depression Detection. We also developed a video based models We have developed a framework to analyze the decisions of Deep Neural Networks trained on facial videos. We test this framework on Automatic Depression Detection. We first train Deep Convolutional Neural Networks (DCNN) pre-trained on Action Recognition datasets and fine-tune on the facial videos. We interpret the model's saliency maps by analyzing face regions and temporal expression semantics. Our framework generates both visual and quantitative explanations on the model's decision. Simultaneously, our video based modeling has improved previous single-face benchmarks of visual Automatic Depression Detection (ADD). We conclude successfully that we have developed the ability to generate hypotheses from a facial model's decisions, and improved Automatic Depression Detection's predictive performance.

Full textEls mamífers marins s'enfronten a nombroses amenaces antropogèniques, incloses les interaccions pesqueres, la contaminació acústica als oceans, les coalicions amb vaixells i els residus marins. El seguiment de l'impacte d’aquestes amenaces en els mamífers marins mitjançant l'avaluació de les tendències poblacionals requereix informació sobre la mida i l’estructura poblacional, la distribució espaciotemporal i el comportament dels animals. El seguiment amb sistemes d’acústica passiva s'ha convertit en un mètode viable per recollir dades a llarg termini de mamífers marins altament mòbils i críptics. Tanmateix, el seguiment acústic passiu encara ha d’afrontar reptes importants en el desenvolupament d'eines d'anàlisi robustes, especialment de cara al recent increment en el seu ús en la conservació aplicada a seguiments a llarg termini i a gran escala d'espècies en perill d'extinció o amb dades insuficients com ara el catxalot o els zífids. Altres reptes són traduir la presència d’animals a estimacions quantitatives de densitat poblacional, degut a que els mètodes han de controlar la variabilitat en la detecció acústica de les espècies en qüestió, els factors ambientals i les freqüències de vocalització específiques de cada espècie. La principal contribució d'aquesta tesi és l'avanç en els mètodes de seguiment quantitatiu a llarg termini de les espècies de cetacis, aplicat a espècies que viuen a grans profunditats com el catxalot i els zífids. Durant aquesta tesi, s’han desenvolupat i aplicat mètodes totalment automatitzats per detectar zífids de diferents poblacions i en diferents condicions. Aquests mètodes han proporcionat informació sobre la capacitat de generalització d'aquestes tècniques automàtiques i han permès fer recomanacions de bones pràctiques. Tanmateix, degut a que la implementació d’aquestes eines no és sempre pràctic, s’han desenvolupat mètodes per al processament de dades de forma expeditiva, que tenen diversos propòsits, que inclouen l’anotació de sons individuals, l’avaluació de dades per proporcionar una tècnica més dinàmica i la classificació per a estudis de seguiment quantitatiu. Aquest treball també presenta la sèrie temporal més llarga documentada de la presència de catxalots obtinguda mitjançant tècniques de seguiment acústic passiu durant més de set anys al Golf de Mèxic. S’han detectat i discriminat les senyals d'ecolocalització d'altres sons per tal de comprendre la distribució i l'estructura espaciotemporal d’aquesta població de catxalots. S’han implementat una sèrie de passos per proporcionar paràmetres i característiques de la població amb l’objectiu d'estimar la densitat mitjançant un mètode basat en senyals d’ecolocalització. Aquesta implementació ha permès l'estudi de la població de catxalots del Golf de Mèxic i ha suposat un progrés significatiu per la comprensió de l'estructura, la distribució i les tendències poblacionals, així com dels potencials impactes a llarg termini del catastròfic vessament de petroli de la plataforma Deepwater Horizon i altres activitats antropogèniques.

Full textEl desarrollo en tecnología de mediciones ha permitido el monitoreo continuo de sistemas complejos a través de múltiples sensores, generando así grandes bases de datos. Estos datos normalmente son almacenados para ser posteriormente analizados con técnicas tradicionales de Prognostics and Health Management (PHM). Sin embargo, muchas veces, gran parte de esta información es desperdiciada, ya que los métodos tradicionales de PHM requieren de conocimiento experto sobre el sistema para su implementación. Es por esto que, para estimar parámetros relacionados a confiabilidad, los enfoques basados en análisis de datos pueden utilizarse para complementar los métodos de PHM. El objetivo de esta tesis consiste en desarrollar e implementar un marco de trabajo basado en técnicas de Aprendizaje Profundo para la estimación del estado de salud de sistemas y componentes, utilizando datos multisensoriales de monitoreo. Para esto, se definen los siguientes objetivos específicos: Desarrollar una arquitectura capaz de extraer características temporales y espaciales de los datos. Proponer un marco de trabajo para la estimación del estado de salud, y validarlo utilizando dos conjuntos de datos: C-MAPSS turbofan engine, y baterías ion-litio CS2. Finalmente, entregar una estimación de la propagación de la incertidumbre en los pronósticos del estado de salud. Se propone una estructura que integre las ventajas de relación espacial de las Convolutional Neural Networks, junto con el análisis secuencial de las Long-Short Term Memory Recurrent Neural Networks. Utilizando Dropout tanto para la regularización, como también para una aproximación bayesiana para la estimación de incertidumbre de los modelos. De acuerdo con lo anterior, la arquitectura propuesta recibe el nombre CNNBiLSTM. Para los datos de C-MAPSS se entrenan cuatro modelos diferentes, uno para cada subconjunto de datos, con el objetivo de estimar la vida remanente útil. Los modelos arrojan resultados superiores al estado del arte en la raíz del error medio cuadrado (RMSE), mostrando robustez en el proceso de entrenamiento, y baja incertidumbre en sus predicciones. Resultados similares se obtienen para el conjunto de datos CS2, donde el modelo entrenado con todas las celdas de batería logra estimar el estado de carga y el estado de salud con un bajo RMSE y una pequeña incertidumbre sobre su estimación de valores. Los resultados obtenidos por los modelos entrenados muestran que la arquitectura propuesta es adaptable a diferentes sistemas y puede obtener relaciones temporales abstractas de los datos sensoriales para la evaluación de confiabilidad. Además, los modelos muestran robustez durante el proceso de entrenamiento, así como una estimación precisa con baja incertidumbre.

Full textDifferences between training and testing conditions may significantly degrade recognition accuracy in automatic speech recognition (ASR) systems. Adaptation is an efficient way to reduce the mismatch between models and data from a particular speaker or channel. There are two dominant types of acoustic models (AMs) used in ASR: Gaussian mixture models (GMMs) and deep neural networks (DNNs). The GMM hidden Markov model (GMM-HMM) approach has been one of the most common technique in ASR systems for many decades. Speaker adaptation is very effective for these AMs and various adaptation techniques have been developed for them. On the other hand, DNN-HMM AMs have recently achieved big advances and outperformed GMM-HMM models for various ASR tasks. However, speaker adaptation is still very challenging for these AMs. Many adaptation algorithms that work well for GMMs systems cannot be easily applied to DNNs because of the different nature of these models. The main purpose of this thesis is to develop a method for efficient transfer of adaptation algorithms from the GMM framework to DNN models. A novel approach for speaker adaptation of DNN AMs is proposed and investigated. The idea of this approach is based on using so-called GMM-derived features as input to a DNN. The proposed technique provides a general framework for transferring adaptation algorithms, developed for GMMs, to DNN adaptation. It is explored for various state-of-the-art ASR systems and is shown to be effective in comparison with other speaker adaptation techniques and complementary to them

Full textComputational rhythm analysis deals with extracting and processing meaningful rhythmical information from musical audio. It proves to be a highly complex task, since dealing with real audio recordings requires the ability to handle its acoustic and semantic complexity at multiple levels of representation. Existing methods for rhythmic analysis typically focus on one of those levels, failing to exploit music’s rich structure and compromising the musical consistency of automatic estimations. In this work, we propose novel approaches for leveraging multi-scale information for computational rhythm analysis. Our models account for interrelated dependencies that musical audio naturally conveys, allowing the interplay between different time scales and accounting for music coherence across them. In particular, we conduct a systematic analysis of downbeat tracking systems, leading to convolutional-recurrent architectures that exploit short and long term acoustic modeling; we introduce a skip-chain conditional random field model for downbeat tracking designed to take advantage of music structure information (i.e. music sections repetitions) in a unified framework; and we propose a language model for joint tracking of beats and micro-timing in Afro-Latin American music. Our methods are systematically evaluated on a diverse group of datasets, ranging from Western music to more culturally specific genres, and compared to state-of-the-art systems and simpler variations. The overall results show that our models for downbeat tracking perform on par with the state of the art, while being more musically consistent. Moreover, our model for the joint estimation of beats and microtiming takes further steps towards more interpretable systems. The methods presented here offer novel and more holistic alternatives for computational rhythm analysis, towards a more comprehensive automatic analysis of music
Abumallouh, Arafat. "A Framework for Enhancing Speaker Age and Gender Classification by Using a New Feature Set and Deep Neural Network Architectures." Thesis, University of Bridgeport, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10689188.
Full textSpeaker age and gender classification is one of the most challenging problems in speech processing. Recently with developing technologies, identifying a speaker age and gender has become a necessity for speaker verification and identification systems such as identifying suspects in criminal cases, improving human-machine interaction, and adapting music for awaiting people queue. Although many studies have been carried out focusing on feature extraction and classifier design for improvement, classification accuracies are still not satisfactory. The key issue in identifying speaker’s age and gender is to generate robust features and to design an in-depth classifier. Age and gender information is concealed in speaker’s speech, which is liable for many factors such as, background noise, speech contents, and phonetic divergences.
In this work, different methods are proposed to enhance the speaker age and gender classification based on the deep neural networks (DNNs) as a feature extractor and classifier. First, a model for generating new features from a DNN is proposed. The proposed method uses the Hidden Markov Model toolkit (HTK) tool to find tied-state triphones for all utterances, which are used as labels for the output layer in the DNN. The DNN with a bottleneck layer is trained in an unsupervised manner for calculating the initial weights between layers, then it is trained and tuned in a supervised manner to generate transformed mel-frequency cepstral coefficients (T-MFCCs). Second, the shared class labels method is introduced among misclassified classes to regularize the weights in DNN. Third, DNN-based speakers models using the SDC feature set is proposed. The speakers-aware model can capture the characteristics of the speaker age and gender more effectively than a model that represents a group of speakers. In addition, AGender-Tune system is proposed to classify the speaker age and gender by jointly fine-tuning two DNN models; the first model is pre-trained to classify the speaker age, and second model is pre-trained to classify the speaker gender. Moreover, the new T-MFCCs feature set is used as the input of a fusion model of two systems. The first system is the DNN-based class model and the second system is the DNN-based speaker model. Utilizing the T-MFCCs as input and fusing the final score with the score of a DNN-based class model enhanced the classification accuracies. Finally, the DNN-based speaker models are embedded into an AGender-Tune system to exploit the advantages of each method for a better speaker age and gender classification.
The experimental results on a public challenging database showed the effectiveness of the proposed methods for enhancing the speaker age and gender classification and achieved the state of the art on this database.

Full textMed tanke på trenden inom forskning av rekommendationssystem, där allt fler rekommendationssystem blir hybrida och designade för flera domäner, så finns det ett behov att framställa en datamängd från sociala medier som innehåller detaljerad information om klädkategorier, klädattribut, samt användarinteraktioner. Nuvarande datasets med inriktning mot mode saknar antingen en hierarkisk kategoristruktur eller information om användarinteraktion från sociala nätverk. Detta projekt har syftet att ta fram två dataset, ett dataset som insamlats från fotodelningsplattformen Instagram, som innehåller foton, text och användarinteraktioner från fashionistas, samt ett dataset som insamlats från klädutbutdet som ges av onlinebutiken Zalando. Vi presenterar designen av en webbcrawler som är anpassad för att kunna hämta data från de nämnda domänerna och är optimiserad för mode och klädattribut. Vi presenterar även en effektiv webblösning som är designad och implementerad för att möjliggöra annotering av stora mängder data från Instagram med väldigt detaljerad information om kläder. Genom att vi inkluderar användarinteraktioner i applikationen så kan vår webblösning ge användaranpassad annotering av data. Webblösningen har utvärderats av utvecklarna samt genom AmazonTurk tjänsten. Den annoterade datan från olika användare demonstrerar användarvänligheten av webblösningen. Utöver insamling av data och utveckling av ett system för webb-baserad annotering av data så har datadistributionerna i två modedomäner, Instagram och Zalando, analyserats. Datadistributionerna analyserades utifrån klädkategorier och med syftet att ge datainsikter. Forskning inom detta område kan dra nytta av våra resultat och våra datasets. Specifikt så kan våra datasets användas i domäner som kräver information om detaljerad klädinformation och användarinteraktioner.

Full textCurrent research in deep learning is primarily focused on using Python as a support language. Go, an emerging language, that has many benefits including native support for concurrency has seen a rise in adoption over the past few years. However, this language is not widely used to develop learning models due to the lack of supporting libraries and frameworks for model development. In this thesis, the use of Go for the development of neural network models in general and convolution neural networks is explored. The proposed study is based on a Go-CUDA implementation of neural network models called GoCuNets. This implementation is then compared to a Go-CPU deep learning implementation that takes advantage of Go's built in concurrency called ConvNetGo. A comparison of these two implementations shows a significant performance gain when using GoCuNets compared to ConvNetGo.

In recent years, the Internet of Things and AI technology have promoted the rapid development of Industry 4.0, and the digitalization and smart production of factories have become an unstoppable trend. However, due to the large increase in the number of devices connected to the Internet, the amount of data transmitted at the same time is very large for data collection. Also, the database design and storage requirements are also important challenges. The transport protocol of the Internet of Things usually uses MQTT to process messages; when the broker for message forwarding accepts too many connections at the same time, data loss and instability may occur. Therefore, how to configure a stable IoT infrastructure is very important. In order to solve the above problems, the thesis proposes an incremental learning framework based on the Industrial Internet of Things, which allows factories to implement smart manufacturing in Industry 4.0 based on the architecture. We also proposed a stable MQTT connection method and data compression method. In the proposed system, MQTT's broker acts as a bridge to forward messages, thereby sharing the pressure on a single broker. In addition, we have also designed a compression mechanism for transmitting sensor data to get the correct data under the condition of less data transmission. Also, the system will retain the data first in case of sudden disconnection is proposed to avoid the data loss during the disconnection period. Finally, we deploy the proposed architecture in a cooperated precision machinery factory in Taichung to collect sensor data, and the operation of the system and the problems that may be encountered are analyzed and discussed in the thesis.

In recent years, with the increase in processor computing power, a substantial increase in the development of many scientific applications, such as weather forecast, financial market analysis, medical technology and so on. Deep Learning can help the computer understand the abstract information such as images, text and sound. Through the neural network, the computer can have the same observation and learning ability as human beings, and even better than human. In this paper, we will use the famous deep learning framework: Caffe, implement to Xeon Phi through the optimization, including the use of vectorization, OpenMP parallel processing, message transfer Interface (MPI), etc., To improve the availability of deep learning framework. Intel recently launched the second generation of Xeon Phi, in addition to the first generation of coprocessor (Coprocessor) products retained, but also added up to 72 core of the main processor, with the power can not be ignored. We evaluate the performance of the deep computing framework across a variety of Intel Xeon platform, including the accuracy comparison between the number of iterations of the test in the training model, and the training time on the different machines before and after optimization, and the use of two Xeon Phi multi-node tests to provide the researchers with a white paper for measurement.

We propose the computation framework that facilitates the inference of the distributed deep learning model to be performed collaboratively by the devices in a distributed computing hierarchy. For example, in Internet-of-Things (IoT) applications, the three-tier computing hierarchy consists of end devices, gateways, and server(s), and the model inference could be done adaptively by one or more computing tiers from the bottom to the top of the hierarchy. By allowing the trained models to run on the actually distributed systems, which has not done by the previous work, the proposed framework enables the co-design of the distributed deep learning models and systems. In particular, in addition to the model accuracy, which is the major concern for the model designers, we found that as various types of computing platforms are present in IoT applications fields, measuring the delivered performance of the developed models on the actual systems is also critical to making sure that the model inference does not cost too much time on the end devices. Furthermore, the measured performance of the model (and the system) would be a good input to the model/system design in the next design cycle, e.g., to determine a better mapping of the network layers onto the hierarchy tiers. On top of the framework, we have built the surveillance system for detecting objects as a case study. In our experiments, we evaluate the delivered performance of model designs on the two-tier computing hierarchy, show the advantages of the adaptive inference computation, analyze the system capacity under the given workloads, and discuss the impact of the model parameter setting on the system capacity. We believe that the enablement of the performance evaluation expedites the design process of the distributed deep learning models/systems.

With the proliferation of deep learning techniques, a significant amount of applications related to home caring systems emerge recently. In particular, detecting abnormal events in a smart home environment has become more mature. According to recent statistics, the most common injury in the elderly population is falling. Existing approaches have mostly conducted intelligence video analysis of single camera for two cases of fall and non-fall. In this paper, we adopt deep learning techniques including convolutional neural networks (CNN) and long short-term memory (LSTM) to construct deep networks for human behavior recognition in a multi-view framework. We set up our experimental environment as a normal residence to collect a large amount of data, and falling is one of the actions included in our dataset. It is not just identifying either fall or non-fall. Our model can identify six human behaviors in total, namely walking, falling, lying down, climbing up, bending, and sitting down. Additionally, we use two cameras as our sensors to efficiently overcome the problem of blind angles and improve performance based on the multi-view setting. After performing a series of image preprocessing in the raw data, we obtain the human silhouette images as the input to our training model. In addition, because the real-world datasets are complicated for analyzing and understanding, the assignment of labeling data is time-consuming and money-consuming. Therefore, we present image clustering based on stacked convolutional auto-encoder (SCAE) which applies the clustering labels to replace the manual labels for auto-labeling. Finally, the experimental results demonstrate that the performance and novelty of our proposed framework.

Full textThe most recent face recognition systems are mainly dependent on feature representations obtained using either local handcrafted-descriptors, such as local binary patterns (LBP), or use a deep learning approach, such as deep belief network (DBN). However, the former usually suffers from the wide variations in face images, while the latter usually discards the local facial features, which are proven to be important for face recognition. In this paper, a novel framework based on merging the advantages of the local handcrafted feature descriptors with the DBN is proposed to address the face recognition problem in unconstrained conditions. Firstly, a novel multimodal local feature extraction approach based on merging the advantages of the Curvelet transform with Fractal dimension is proposed and termed the Curvelet–Fractal approach. The main motivation of this approach is that theCurvelet transform, a newanisotropic and multidirectional transform, can efficiently represent themain structure of the face (e.g., edges and curves), while the Fractal dimension is one of the most powerful texture descriptors for face images. Secondly, a novel framework is proposed, termed the multimodal deep face recognition (MDFR)framework, to add feature representations by training aDBNon top of the local feature representations instead of the pixel intensity representations. We demonstrate that representations acquired by the proposed MDFR framework are complementary to those acquired by the Curvelet–Fractal approach. Finally, the performance of the proposed approaches has been evaluated by conducting a number of extensive experiments on four large-scale face datasets: the SDUMLA-HMT, FERET, CAS-PEAL-R1, and LFW databases. The results obtained from the proposed approaches outperform other state-of-the-art of approaches (e.g., LBP, DBN, WPCA) by achieving new state-of-the-art results on all the employed datasets.

It is very well-known in the industry that the Synopsys Design Compiler can achieve better area reduction while maintaining given design constraints by carefully selecting a smaller target gate-level cell library from primitive one at synthesis stage. The selecting process is extremely time consuming and inefficient. Therefore, an automatic selecting procedure is in demand. In this paper, we propose a deep reinforcement learning based logic synthesis framework to achieve further area reduction while maintaining given design constraints, and we apply transfer learning based on the same framework to improve the optimization quality. Experimental results show that we can obtain up to 25.61% area reduction with transfer learning.

Both cameras and IoT devices have their particular capabilities in tracking human behaviors and statuses. Their correlations are, however, unclear. In this work, we propose a framework for integrating video and wearable sensing data for smart surveillance, such as people identification and tracking. Using biometric features such as fingerprint, iris, gait, and face may lead to good recognition results. However, these approaches all have their limitations in distance and privacy concerns. In this work, we present a data fusion framework based on deep learning for fusing the aforementioned data. Here, using deep learning is to help adaptively learn the hidden bindings of these data. We demonstrate how to retrieve data of interest from IoT devices, which are attached on human objects, and correctly tag them on the human objects captured by a camera, thus correlating video and IoT data. Potential applications of this framework include smart surveillance and friendly visualization. We then show several case studies, including integrating video data with body movement and physiological data.

Face Detection is one of the most commonly used techniques in Deep Learning Reaearch, such as autofocus built into digital cameras, Face Recognition Payment in Unmanned Stores, Personnel Access Control System, Face Unlocking of Smart Phones, etc... Convolutional Neural Network is one of the currently convenient and accurate methods for implementing face detection technology in Deep Learning approach. Among the many researches on Face Detection, the most famous paper could be MTCNN(Multi-task Cascaded Convolutional Networks). The MTCNN Model has higher accuracy and shorter detection time than most other face detection methods. The major challenge is that the overall accuracy of MTCNN model is proportional to the amount of training data and the model training is usually very consuming. In general, the common way to improve the accuracy of the neural network model is to increase the number of neurons in the neural layer of the model structure(widening) or add a new neural layer(deepening). Although the accuracy of the model can be improved after using these two approaches, the neural network structure will become more complicated. An overly complex neural network structure does not only makes it difficult to improve its performance, also increases the overall model training time. In this thesis, we use the principle of diversity in data augmentation and use of convolution kernel decomposition to improve the accuracy of the MTCNN model. Try to improve accuracy as well as to reduce the amount of training data and training time applying. From the experiments, we found that the accuracy of the MTCNN model after the diversity principle and the convolution kernel decomposition mechanism is much higher than the original model and the training time on each stage is also shortened. In order to further enhance the effect of the MTCNN model, the XLA compiler function of the deep learning framework, TensorFlow, is included to improve the computational power of the model. Consequently, both the detection accuracy and the training time reduction can be effectively improved.
