Testo completoData shared throughout the world has a major impact on the lives of billions of people. It is critical to be able to analyse this data automatically in order to measure and alter its impact. This analysis is tackled by training deep neural networks, which have reached competitive results in many domains. In this work, we focus on the understanding of daily life images, in particular on the interactions between objects and people that are visible in images, which we call visual relations.To complete this task, neural networks are trained in a supervised manner. This involves minimizing an objective function that quantifies how detected relations differ from annotated ones. Performance of these models thus depends on how widely and accurately annotations cover the space of visual relations.However, existing annotations are not sufficient to train neural networks to detect uncommon relations. Thus we integrate knowledge into neural networks during the training phase. To do this, we model semantic relationships between visual relations. This provides a fuzzy set of relations that more accurately represents visible relations. Using the semantic similarities between relations, the model is able to learn to detect uncommon relations from similar and more common ones. However, the improved training does not always translate to improved detections, because the objective function does not capture the whole relation detection process. Thus during the inference phase, we combine knowledge to model predictions in order to predict more relevant relations, aiming to imitate the behaviour of human observers

Testo completoImage processing has been a very active area of research for years. The interpretation of images is one of its most important branches because of its socio-economic and scientific applications. However, the interpretation, like most image processing processes, requires a segmentation phase to delimit the regions to be analyzed. In fact, interpretation is a process that gives meaning to the regions detected by the segmentation phase. Thus, the interpretation phase can only analyze the regions detected during the segmentation. Although the ultimate objective of automatic interpretation is to produce the same result as a human, the logic of classical techniques in this field does not marry that of human interpretation. Most conventional approaches to this task separate the segmentation phase from the interpretation phase. The images are first segmented and then the detected regions are interpreted. In addition, conventional techniques of segmentation scan images sequentially, in the order of pixels appearance. This way does not necessarily reflect the way of the expert during the image exploration. Indeed, a human usually starts by scanning the image for possible region of interest. When he finds a potential area, he analyzes it under three view points trying to recognize what object it is. First, he analyzes the area based on its physical characteristics. Then he considers the region's surrounding areas and finally he zooms in on the whole image in order to have a wider view while considering the information local to the region and those of its neighbors. In addition to information directly gathered from the physical characteristics of the image, the expert uses several sources of information that he merges to interpret the image. These sources include knowledge acquired through professional experience, existing constraints between objects from the images, and so on.The idea of the proposed approach, in this manuscript, is that simulating the visual activity of the expert would allow a better compatibility between the results of the interpretation and those ofthe expert. We retain from the analysis of the expert's behavior three important aspects of the image interpretation process that we will model in this work: 1. Unlike what most of the segmentation techniques suggest, the segmentation process is not necessarily sequential, but rather a series of decisions that each one may question the results of its predecessors. The main objective is to produce the best possible regions classification. 2. The process of characterizing an area of interest is not a one way process i.e. the expert can go from a local view restricted to the region of interest to a wider view of the area, including its neighbors and vice versa. 3. Several information sources are gathered and merged for a better certainty, during the decision of region characterisation. The proposed model of these three levels places particular emphasis on the knowledge used and the reasoning behind image segmentation

Testo completoIn recent decades, the New Product Development Process (PDP) has become an increasingly complex and iterative process due to the diversification and customization of products and their complexity. Moreover, the design of the associated production systems becomes a very complex task, knowing that this phase is linked to the decision-making of the production strategy which have an impact on long-term and which involve an important commitment of financial resources. Thus, companies must overcome these challenges for design, develop and produce faster and cheaper products with better quality. In this context, the Digital Factory (DF) is a solutionbased on the use of numerical methods and tools to examine, qualify and compare the complex production systems and thus, help to make the optimal decisions. However, the experts of simulation still encounter difficulties in the decision-making due to the lack of organization, information and knowledge. In this research, we focus on this last point and we propose a knowledge management system called "KSim" dedicated to the management of all knowledge for the development of DF projects and which supports the collaboration and communication between all PDP actors to facilitate to make better decisions as soon as possible

Testo completoPLM (Product Lifecycle Management) Systems allow traceability of information and facilitate the reduction of products development cycle. Besides the aspect related to information management, they aim at bringing together all technical data needed to develop new products and also they contribute to improve business processes. Our PhD work define a methodology of PLM system deployment that incorporates the knowledge capitalization dimension. Based on a business processes formalization, elements of knowledge are extracted and used to enrich the data model. This model revolves around two axes: an "information" axis and a "knowledge"axis. Each axis is devided into four steps: identify, model, use and evaluate. The identification stage is to define the data model of the system and activities requiring specific business knowledge. The modeling phase is to configure the system to integrate the defined model in the PLM system but also to formalize extracted tacit knowledge. Then comes the user through the use of the system. Finally, we propose to evaluate the system from product, process and organization modeling but also from generated knowledge within the system. The case study of a process of bidding for the Marmillon SAS company which is a subcontractor in the field of plastics, specialist of injection and extrusion processes for automotive parts allow to validate our approach

Testo completoExtracting and maintaining up-to-date knowledge from diverse linguistic sources is imperative for the benefit of public health. While professional sources, including scientific journals and clinical notes, provide the most reliable knowledge, observations reported in patient forums and social media can bring complementary information for certain themes. Spotting entities and their relationships in these varied sources is particularly valuable. We focus on relation extraction in the medical domain. At the outset, we highlight the inconsistent terminology in the community and clarify the diverse setups used to build and evaluate relation extraction systems. To obtain reliable comparisons, we compare systems using the same setup. Additionally, we conduct a series of stratified evaluations to further investigate which data properties affect the models' performance. We show that model performance tends to decrease with relation density, relation diversity, and entity distance. Subsequently, this work explores a new training paradigm for biomedical relation extraction: prompt-based methods with masked language models. In this context, performance depends on the quality of prompt design. This requires manual efforts and domain knowledge, especially when designing the label words that link model predictions to relation classes. To overcome this overhead, we introduce an automated label word generation technique leveraging a dependency parser and training data. This approach minimizes manual intervention and enhances model performance with fewer parameters to be fine-tuned. Our approach performs on par with other verbalizer methods without additional training. Then, this work addresses information extraction from text written by laypeople about adverse drug reactions. To this end, as part of a joint effort, we have curated a tri-lingual corpus in German, French, and Japanese collected from patient forums and social media platforms. The challenge and the potential applications of the corpus are discussed. We present baseline experiments on the corpus that highlight three points: the effectiveness of a multilingual model in the cross-lingual setting, preparing negative samples for relation extraction by considering the co-reference and the distance between entities, and methods to address the highly imbalanced distribution of relations. Lastly, we integrate information from a medical knowledge base into the prompt-based approach with autoregressive language models for biomedical relation extraction. Our goal is to use external factual knowledge to enrich the context of the entities involved in the relation to be classified. We find that general models particularly benefit from external knowledge. Our experimental setup reveals that different entity markers are effective across different corpora. We show that the relevant knowledge helps, though the format of the prompt has a greater impact on performance than the additional information itself
