Testo completoTiivistelmä Tämän väitöskirjan tarkoituksena on tutkia organisaation oppimisen ja sen eri osatekijöiden roolia prosessi-innovaatioiden luomisessa ja muutoksen aikaansaamisessa organisaatiossa. Organisaation oppimista tutkittiin ja aineisto kerättiin prosessien kehittämisprojekteissa, joissa prosessisimulaatioita käytettiin prosessi-innovaatioiden menetelmänä. Tutkimuksen aineisto kerättiin pääsiassa vuosien 1988–2001 aikana. Tässä väitöskirjassa näitä tuloksia analysoidaan vallitsevien organisaatio-oppimisen teorioiden valossa prosessi-innovaatioiden ja muutoksen johtamisen asiayhteydessä. Erityisesti tutkitaan oppimisen mahdollistajia, oppimisen tuloksia (aineettomia/aineellisia), oppimisen polkuja ja kaikkien näiden keskinäisiä suhteita. Tutkimusmenetelmänä on käytetty laadullista pitkittäistä toimintatutkimusta tapaustutkimuksineen ja abduktiivisine päättelyineen. Aineisto koostuu 34 tapaustutkimuksesta ja 99 prosessisimulaatiosta, jotka toteutettiin 12 eri toimialalla, ja vaihtelevat ydinprosesseista tukiprosesseihin. Suurimmaksi osaksi tapausorganisaatiot olivat suomalaisia yrityksiä, ja yksi tapausorganisaatio oli sveitsiläinen. Projektiryhmät olivat pääasiassa suomalaisia, mutta monikulttuurinen ryhmä osallistui prosessisimulointiin viidessä tapaustutkimuksessa. Jokaisessa projektissa prosessisimulointia käytettiin ainakin kerran muutosprojektin aikana, joissakin tapauksissa jopa viidestä kahdeksaan kertaan. Väitöskirjan viiden artikkelin aineiston analysointi suoritettiin abduktiivisen päättelyn periaattein, ja tutkimuksen tulokset esitetään tutkimuskysymysten mukaisesti. Tutkimuksen teoreettinen tulos kohdistuu neljään osa-alueeseen. Tulokset lisäävät ymmärrystä 1) oppimisen mahdollistajista, niiden suhteesta toisiinsa ja vaikutuksesta oppimiseen ja prosessi-innovaatioihin, 2) aineettomien ja aineellisten oppimistulosten roolista yksilön ja organisaation oppimisprosesseissa, ja 3) prosessi-innovaatioiden ja niihin liittyvien muutosprosessien oppimisen poluista. Tutkimus myös määrittelee 4) prosessi-innovaatioita koskevien muutosprojektien oppimista korostavan mallin. Tutkimuksen tuloksia voitaneen soveltaa Pohjois- ja Länsi-Euroopan yritysmaailmassa. Tutkimus korostaa yksilön ja organisaation oppimisen merkitystä prosessi-innovaatioiden luomisessa ja lisäksi se määrittelee vaikuttavan prosessi-innovaatioiden kehittämisen ja käyttöönoton menetelmän piirteet

Human intelligence is a product of cooperation among many different specialists. Much of this cooperation must be learned, but we do not yet have a mechanism that explains how this might happen for the "high-level" agile cooperation that permeates our daily lives. I propose that the various specialists learn to cooperate by learning to communicate, basing this proposal on the phenomenon of communication bootstrapping, in which shared experiences form a basis for agreement on a system of signals. In this dissertation, I lay out a roadmap for investigating this hypothesis, identifying problems that must be overcome in order to understand the capabilities of communication bootstrapping and in order to test whether it is exploited by human intelligence. I then demonstrate progress along the course of investigation laid out in my roadmap: * I establish a measure of developmental cost that allows me to eliminate many possible designs * I develop a method of engineering devices for use in models of intelligence, including characterizing their behavior under a wide variety of conditions and compensating for their misbehavior using failure simplification. * I develop mechanisms that reliably produce communication bootstrapping such that it can be used to connect specialists in an engineered system. * I construct a demonstration system including a simulated world and pair of observers that learn world dynamics via communication bootstrapping.

Testo completoThis study was designed to investigate possible changes in the use of four specific learning strategies by students who had learning disabilities: using a device, thinking about knowledge, finding a starting point, and acting differently in the future. The five student participants were instructed in a special education pull-out reading classroom using the blended learning classroom model. The researcher explored behavioral changes related to student participants’ use of these learning strategies in general education classrooms. This study attempted to investigate student participants’ and general education teachers’ perceptions of the four learning strategies. A math teacher, a social studies teacher, and a science teacher from the researcher’s teaching team also contributed their perceived observations of student participants’ use of the four learning strategies in their classrooms. The triangulation of data used in this study was achieved through use of pre-surveys and post-surveys that inquired into use of learning strategies on the parts of student participants and general education teachers at the inception of the study and again at its conclusion. Interviews with each of the study’s participants were also conducted at the conclusion of the study. Student binders used by the student participants in the blended learning instructional model were analyzed for evidence. The results of the study indicated that although according to survey data, students did not demonstrate changes in their ability to use the four learning strategies, most student participants reported using the strategies in their general education classes.

Testo completoThe thesis contributions resolves around sequential decision taking and more precisely Reinforcement Learning (RL). Taking its root in Machine Learning in the same way as supervised and unsupervised learning, RL quickly grow in popularity within the last two decades due to a handful of achievements on both the theoretical and applicative front. RL supposes that the learning agent and its environment follow a stochastic Markovian decision process over a state and action space. The process is said of decision as the agent is asked to choose at each time step an action to take. It is said stochastic as the effect of selecting a given action in a given state does not systematically yield the same state but rather defines a distribution over the state space. It is said to be Markovian as this distribution only depends on the current state-action pair. Consequently to the choice of an action, the agent receives a reward. The RL goal is then to solve the underlying optimization problem of finding the behaviour that maximizes the sum of rewards all along the interaction of the agent with its environment. From an applicative point of view, a large spectrum of problems can be cast onto an RL one, from Backgammon (TD-Gammon, was one of Machine Learning first success giving rise to a world class player of advanced level) to decision problems in the industrial and medical world. However, the optimization problem solved by RL depends on the prevous definition of a reward function that requires a certain level of domain expertise and also knowledge of the internal quirks of RL algorithms. As such, the first contribution of the thesis was to propose a learning framework that lightens the requirements made to the user. The latter does not need anymore to know the exact solution of the problem but to only be able to choose between two behaviours exhibited by the agent, the one that matches more closely the solution. Learning is interactive between the agent and the user and resolves around the three main following points: i) The agent demonstrates a behaviour ii) The user compares it w.r.t. to the current best one iii) The agent uses this feedback to update its preference model of the user and uses it to find the next behaviour to demonstrate. To reduce the number of required interactions before finding the optimal behaviour, the second contribution of the thesis was to define a theoretically sound criterion making the trade-off between the sometimes contradicting desires of complying with the user's preferences and demonstrating sufficiently different behaviours. The last contribution was to ensure the robustness of the algorithm w.r.t. the feedback errors that the user might make. Which happens more often than not in practice, especially at the initial phase of the interaction, when all the behaviours are far from the expected solution

Learning optimal policies in the presence of non-stationary policies of other simultaneously learning agents is a major challenge in multiagent reinforcement learning (MARL). The difficulty is further complicated by other challenges, including the multiagent credit assignment, the high dimensionality of the problems, and the lack of convergence guarantees. As a result, many experiences are often required to learn effective multiagent policies. This thesis introduces two frameworks to reduce the sample complexity in MARL. The first framework presented in this thesis provides a method to reduce the sample complexity by exchanging knowledge between agents. In particular, recent work on agents that learn to teach other teammates has demonstrated that action advising accelerates team-wide learning.
However, the prior work simplified the learning of advising policies by using simple function approximations and only considering advising with primitive (low-level) actions, both of which limit the scalability of learning and teaching to more complex domains. This thesis introduces a novel learning-to-teach framework, called hierarchical multiagent teaching (HMAT), that improves scalability to complex environments by using a deep representation for student policies and by advising with more expressive extended-action sequences over multiple levels of temporal abstraction. Our empirical evaluations demonstrate that HMAT improves team-wide learning progress in large, complex domains where previous approaches fail. HMAT also learns teaching policies that can effectively transfer knowledge to different teammates with knowledge of different tasks, even when the teammates have heterogeneous action spaces.
The second framework introduces the first policy gradient theorem based on meta-learning, which enables fast adaptation (i.e., need only a few iterations) with respect to the non-stationary fellow agents in MARL. The policy gradient theorem that we prove inherently includes both a self-shaping term that considers the impact of a meta-agent's initial policy on its adapted policy and an opponent-shaping term that exploits the learning dynamics of the other agents. We demonstrate that our meta-policy gradient provides agents to meta-learn about different sources of non-stationarity in the environment to improve their learning performances.

Testo completoOs modelos de aprendizagem automática dependem dos dados para aprender qualquer tarefa e, dependendo da diversidade de cada um dos elementos da tarefa e dos objetivos do projeto, a quantidade de dados pode ser elevada, o que, por sua vez, pode aumentar exponencialmente o tempo de aprendizagem e o custo computacional. Embora a maioria do treino dos modelos de aprendizagem automática hoje seja feito usando GPUs (unidade de processamento gráfico), ainda é necessária uma quantidade enorme de tempo de treino para obter o desempenho desejado. Este trabalho tem como objetivo analisar os algoritmos de aprendizagem de aprendizagem ou popularmente conhecidos como metalearning, que são métodos que não apenas tentam melhorar a velocidade de aprendizagem, mas também o desempenho do modelo e, além disso, requerem menos dados e envolvem várias tarefas. O conceito envolve o treino de um modelo que aprende constantemente a aprender tarefas novas em ritmo acelerado, a partir de tarefas aprendidas anteriormente. Para a revisão do trabalho relacionado, será dada atenção aos métodos baseados em otimização e, mais precisamente, ao MAML (Model Agnostic MetaLearning), porque em primeiro lugar é um dos métodos de metalearning mais populares e em segundo lugar, esta tese foca a criação de um método baseado em MAML, chamado MAML-DBL, que usa uma técnica de taxa de aprendizagem adaptável com limites dinâmicos que permite obter convergência rápida no início do processo de treino e boa generalização no fim. A proposta variante de MAML tem como objetivo tentar evitar o desaparecimento das taxas de aprendizagem durante o treino e a desaceleração no fim onde entradas densas são predominantes, embora possa ser necessário um ajuste adicional dos hiperparâmetros para alguns modelos ou onde entradas esparsas podem ser predominantes, para melhorar o desempenho. O MAML-DBL e o MAML foram testados nos conjuntos de dados mais comumente usados para modelos de metalearning, e com base nos resultados das experiências, o método proposto mostrou um desempenho bastante competitivo em alguns dos modelos e até superou o baseline em alguns dos testes realizados. Os resultados obtidos com o MAML e MAML-DBL (num dos conjuntos de dados) mostram que os métodos de metalearning são soluções altamente recomendáveis sempre que um bom desempenho, menos dados e um modelo versátil ou com várias tarefas são necessários ou desejados.

Testo completoO sistema de saúde, que é ubiquamente reconhecido como um dos sistemas mais influentes da sociedade, enfrenta novos desafios desde o ínicio da década. A miríade de dados fisiológicos gerados por indíviduos, nomeadamente no sistema de saúde, está a gerar um fardo para os médicos, perdendo a eficiência no conjunto dos dados do paciente. Os sistemas de informação e, mais espcificamente, da inovação de algoritmos de aprendizagem profunda (DL) têm sido usados na procura de uma solução para este problema. Esta tese tem o objetivo de ter um impacto na pesquisa e na indústria de biosinais, apresentando soluções de DL que poderiam melhorar esta área de investigação. Para esse fim, é discutido um extenso estudo de como incorporar e implementar redes neurais convolucionais (CNN), redes neurais recursivas (RNN) e redes totalmente conectadas para o estudo de biosinais. Diferentes arquiteturas foram exploradas para processamento e tomada de decisão de sinais e foram implementadas em três cenários diferentes: (1) Aprendizagem e síntese de biosinais; (2) sistemas biométricos com o uso de eletrocardiograma (ECG), e; (3) Sistema de detecção de anomalias no ECG. Em (1) uma arquitetura baseada na RNN foi capaz de replicar autonomamente três tipos de sinais biológicos com um alto grau de confiança. Quanto a (2) três arquiteturas baseadas em CNN e uma arquitetura baseada em RNN (a mesma usada em (1)) foram usadas para ambas as identificações, atingindo valores acima de 90 % para conjuntos de dados à base de eletrodos (Fantasia, ECG-ID e MIT -BIH) e 75 % para o conjunto de dados fora da pessoa (CYBHi) e autenticação, atingindo taxas de erro iguais (EER) de quase 0 % para Fantasia e MIT-BIH e abaixo de 4 % para CYBHi. Quanto a (3) a abstração de sinais limpos e assimptomáticos de ECG e a detecção do seu desvio foram feitas e testadas em dois cenários diferentes: na presença de ruído usando um autocodificador e uma rede totalmente conectada (atingindo 99 % de precisão na classificação binária e 71 % na multi-classe), e; eventos de arritmia incluindo um RNN na arquitetura anterior (57 % de precisão e 61 % de sensibilidade). Em suma, esses sistemas são mais uma vez demonstrados como capazes de produzir resultados inovadores. A incorporação de vários sistemas de inteligência artificial em um unico sistema pederá desencadear a próxima geração de medicina preventiva. Os algoritmos ao terem acesso a diferentes estados fisiológicos e anatómicos, podem produzir soluções mais informadas para os problemas que se possam enfrentar no futuro, aumentando o desempenho de sistemas autónomos de prevenção que poderiam ser usados na vida quotidiana, nomeadamente em locais remotos onde o acesso à medicinas é limitado. Estes sistemas também ajudarão o estudo do comportamento do sinal e como eles são feitos no contexto da vida real, pois a IA explicável pode desencadear essa percepção e vincular os estados internos de uma rede às características biológicas.

Accompanying with the development of mobile technology, learning activities are no longer limited in classrooms or specific places. They can be performed at outdoor. Such kind of ubiquitous learning becomes more and more important. On the other hand, many researches reveal that inquiry-based learning turns students from passive knowledge receivers into active learning-activity participants, and benefits the students in promoting their critical thinking abilities. Thus Inquiry-based Ubiquitous Learning becomes an emergent research topic. However, further investigation is needed to verify the superiority of the inquiry-based ubiquitous learning over normal ubiquitous learning environment. Moreover, it is interesting to develop an inquiry-based ubiquitous learning approach to further promote students’ critical thinking. In recent years, personalized learning that considers the individual differences of students has gained much more attentions. Nevertheless, little related research is done on inquiry-based ubiquitous learning. To investigate the effects of learning environment, learning approach and learning style on inquiry-based ubiquitous learning, an inquiry-based ubiquitous learning system is proposed and developed. The 5E learning cycle is applied as the inquiry-based ubiquitous learning approach. Moreover, the Kolb’s learning style is considered to allocate suitable types of guidance problems in the inquiry-based ubiquitous learning. A serial of field experiments are conducted and the analysis results show that both learning achievement and critical thinking ability are promoted in the proposed inquiry-based learning environment. The full 5E learning cycle further promotes the critical thinking and the personalized learning strategy further promotes the learning achievement.
