Title: Facial Expressions of Emotions Author: Bc. Markéta Zajícová Department: Department of Psychology, Charles University in Prague, Faculty of Arts Supervisor: doc. PhDr. MUDr. Mgr. Radvan Bahbouh, Ph.D. Abstract: The theses is dedicated to facial expressions of emotions, it begins with a brief introduction to the topic of emotions as one of the cognitive functions, there is a definition of the term, classification of emotions and their psychopathology, it briefly summarizes the various theories of emotions. The greater part of the theoretical section is devoted to basic emotions and their manifestation in the face, as well as the ability to recognize and imitate them. The theoretical part is closed by the topic of emotional intelligence as a unifying element that highlights the importance of this issue. Empirical part is primarily focused on two abilities related to facial expressions of emotions, specifically the recognition and the production of them, then links these capabilities with additional characteristics as the gender, the education and their self-estimation. The main finding of this theses is that there is a statistical significant relationship (ρ=0.35, α=0.05) between the emotion recognition and production. Key words: Basic Emotion, Facial Expressions of Emotions, Emotion Recognition,...

Umělá inteligence v žurnalistice a její využití na příkladech tiskových agentur Reuters a AP / Artificial nintelligence in journalism and its use on examples of press agencies Reuters and AP

Jahn, Oliver January 2019 (has links)
Cílem této diplomové práce je představení zcela nového způsobu vytváření i distribuování zpráv a obsahu, kdy se do tohoto jinak tradičně "lidského odvětví" začínají v poslední době promítat automatizované a chytré počítačové systémy využívající umělou inteligenci. Hodlám vysvětlit, co tento pojem znamená s ohledem na mediální prostor, představit jeho poměrně krátkou historii a popsat, jak dochází k jeho zavádění v žurnalistické praxi. Jelikož se jedná o stále vyvíjející se část možná budoucí novinářské práce, která je zatím v začátcích, nepracují s ní zatím ve větším tuzemská média, i když postupně začínají experimentovat například se strojovou žurnalistikou, tedy předstupněm plně automatizované umělé inteligence. Výzkum je proto zaměřen na vývoj a používání umělé inteligence tiskovými agenturami Reuters a AP, které s těmito nástroji už začaly pracovat a na jejichž případu hodlám ukázat možný budoucí nástup i praxi. V závěru zhodnotím největší výhody i nejdiskutovanější etické problémy fungování umělé inteligence v žurnalistice.

Revisão de crenças em lógicas de descrição e em outras lógicas não clássicas / Belief revision in description logics and other non-classical logics

Ribeiro, Marcio Moretto 20 September 2010 (has links)
A area de revisão de crenças estuda como agentes racionais mudam suas crencas ao receberem novas informações. O marco da area de revisão de crenças foi a publicacão do trabalho de Alchourron, Gardenfors e Makinson. Nesse trabalho conhecido como paradigma AGM foram denidos criterios de racionalidade para tipos de mudanca de crencas. Desde então, a área de revisão de crenças foi influenciada por diversas disciplinas como filosoa, computacão e direito. Paralelamente ao desenvolvimento da area de revisão de crenças, os últimos 20 anos foram marcados por um grande avanço no estudo das logicas de descrição. Tal avanço, impulsionado pelo desenvolvimento da web-semântica, levou a adoção de linguagens inspiradas em logicas de descrição (OWL) como padrão para se representar ontologias na web. Nessa tese tratamos do problema de aplicar a teoria da revisão de crenças a lógicas não clássicas e especialmente a logicas de descric~ao. Trabalhos recentes mostraram que o paradigma AGM e incompatvel com diversas logicas de descricão. Estendemos esses resultados mostrando outras lógicas que não são compatíveis com o paradigma AGM. Propomos formas de aplicar a teoria de revisão tanto em bases quanto em conjuntos de crencas a essas logicas. Alem disso, usamos algoritmos conhecidos da área de depuração de ontologias para implementar operações em bases de crenças. / Belief revision theory studies how rational agents change their beliefs after receiving new information. The most in uential work in this area is the paper of Alchourron, Gardenfors and Makinson. In this work, known as AGM paradigm rationality criteria for belief change were dened. Since then, the eld has been in uenced by many areas like philosophy, computer science and law. Parallel to the development of belief revision eld, in the past 20 years there was a huge grow in the study of description logics. The climax of this development was the adoption of OWL (a language based on description logics) as the standard language to represent ontologies on the web. In this work we deal with the problem of applying belief revision in to non-classical logics, specially description logics. Recent works showed that the AGM paradigm is not compliant with several description logics. We have extended this work by showing that other logics are not compliant with AGM paradigm. Furthermore, we propose alternative ways to apply belief revision techniques to these logics. Finally, we show that well known algorithms from the area of ontology debugging eld can be used to implement the proposed constructions.

Efektivní reprezentace a konverze plánovacích problémů / Efficient Representations and Conversions of Planning Problems

Toropila, Daniel January 2014 (has links)
Title E cient Representations and Conversions of Planning Problems Author Daniel Toropila Department Department of Theoretical Computer Science and Mathematical Logic Supervisor prof. RNDr. Roman Barták, Ph.D. Abstract The e ciency of all types of planning systems is strongly dependent on the in- put formulation, the structure of which must be exploited in order to provide an improved e ciency. Hence, the state-variable representation (SAS+ ) has be- come the input of choice for many modern planners. As majority of planning problems is encoded using a classical representation, several techniques for trans- lation into SAS+ have been developed in the past. These techniques, however, ignore the instance-specific information of planning problems. Therefore, we in- troduce a novel algorithm for constructing SAS+ that fully utilizes the information from the goal and the initial state. By performing an exhaustive experimental evaluation we demonstrate that for many planning problems the novel approach generates a more e cient encoding, providing thus an improved solving time. Finally, we present an overview and performance evaluation of several constraint models based on SAS+ and finite-state automata, showing that they represent a competitive alternative in the category of constraint-based planners.

Infant handling in male Barbary macaques

KUBĚNOVÁ, Barbora January 2017 (has links)
Non-maternal manipulation of infants also called infant handling in male Barbary macaques attracts scientific attention due to its intensity in combination with promiscuity of the species that should select against paternal care. This PhD thesis consists of four studies that investigate male infant handling in wild group of Barbary macaques in Morocco. The studies are based on original data and the results provide new information about the behaviour and thus significantly contribute to its explanation. First, we offer new insights into the relationship between distribution of mating and infant handling, and ask whether it can be better explained by paternal effort or future mating success with infants' mothers. Second, we broaden the range of explanations beyond the original hypothesis of relationship management for male-infant-male interactions. Third, we focus on the question whether males use knowledge of third party relationship when distributing infant handling interactions. Fourth, we demonstrate how care of infants can surprisingly contribute to the reintroduction of an infant who is not native in its group.

Sistema de recomendação hídrido para bibliotecas digitais que suportam o protocolo OAI PMH. / Hibrid recommender system for digital libraries what supporting the protocol OAI PMH.

Nascimento Júnior, Hélio Martins do 22 December 2008 (has links)
The growth of Web technologies has benefited researchers and the academic community by supporting the access of electronic publications as soon as they have been finished and published. In this context, Digital Libraries emerges as complex information systems which are essential for disseminating and preserving data, information and knowledge. However, due to the high amount of content available on the Web, specially in Digital Libraries, users face many correlated options, what result in the phenomenon known as information overload. Aiming to decrease or even eliminate these diffculties, recommender systems for Digital Libraries have been proposed and developed. This work presents a personalized recommender system which presents alternative ways to achieve better query results. For this, the main existing approaches of automatic recommendation have been studied in order to identify extension points and points to be improved. The proposed recommender system follows a hybrid approach which combines filtering techniques, content-based recommendation and collaborative recommendation. A hybrid recommendation engine has been proposed, which uses standard technologies for content description (Dublin Core), for communication with Digital Libraries (OAI-PMH Protocol ), as well as the user profile extracted from the curriculum vitae Lattes. The proposed solution has been evaluated in the context of the CiteSeer database, which contains papers and articles in the Dublin Core format. The preliminary results has showed an improvement in the quality of recommendation, thus presenting a better precision and coverage, when compared with existing approaches based either on content-based recommendation or on collaborative recommendation / O crescimento acelerado das tecnologias Web tem beneficiado pesquisadores e acadêmicos, pois as publicações de pesquisa podem ser acessadas eletronicamente tão logo elas tenham sido finalizadas e publicadas. Nesse contexto, surgem as Bibliotecas Digitais como um sistema de informação complexo que possui uma série de atividades que integram coleções, serviços e pessoas em suporte ao completo ciclo de criação, disseminação, acesso e preservação de dados, informação e conhecimento. No entanto, devido a enorme quantidade de conteúdo presente na Web, em particular nas Bibliotecas Digitais, usuários acabam se deparando com uma diversidade muito grande de opções, o que leva ao fenômeno conhecido como sobrecarga de informação. Com o objetivo de contribuir para amenizar ou até mesmo eliminar essas dificuldades, sistemas de recomendação para Bibliotecas Digitais têm sido propostos e desenvolvidos. Este trabalho segue essa direção, investigando soluções alternativas para alcançar mais qualidade nas indicações geradas por um sistema de recomendação na sua tarefa de ajudar os seus usuários. Para isso estudou-se as abordagens tratadas na literatura especializada sobre tais sistemas, propondo-se em seguida, um sistema de recomendação personalizada de artigos científicos para Bibliotecas Digitais. Tal sistema seguiu uma abordagem híbrida, procurando tirar proveito das características interessantes identificadas nas técnicas de filtragem e recomendação baseadas em conteúdo e colaborativa. Nesse sentido desenvolveu-se um engenho de recomendação híbrido que se utiliza de tecnologias padrão para a descrição de conteúdo (Padrão Dublin Core), comunicação com Bibliotecas Digitais (Protocolo OAI-PMH) e perfil do pesquisador (Currículo Lattes). Finalmente, avaliou-se o sistema proposto sobre uma base de dados do CiteSeer contendo artigos no formato Dublin Core, tendo os resultados preliminares mostrado-se satisfatórios melhorando a precisão na recomendação e a cobertura quando comparado com sistemas que implementam abordagens baseada em conteúdo e colaborativa isoladamente

Development and validation of new methods of distribution of initial population on genetic algorithms for the problem of protein-ligand docking / Desenvolvimento e validação de novos métodos de distribuição da população inicial em algoritmos genéticos para o problema de docking proteína-ligante

Reinaldo Bellini Gonçalves 05 June 2008 (has links)
The methods of protein-ligand docking are computational methods usedto predict the mode of binding of molecules into drug candidates for its receptor. The docking allows tests of hundreds of compounds in ashort space of time, assisting in the discovery of new drug candidates. The great complexity that involves the binding of protein-ligand complex, makes the problem of docking computationally difficult to be solved. In this work, we used the Genetic Algorithms which is a technique of optimization based on the theory of biological evolution of Darwin. The proposed algorithm was implemented and tested initially by Camila S. de Magalhães in her doctoral thesis, with the Group of Molecular Modeling of Biological Systems at LNCC, with a range of 5 ligands of HIV-1 protease. It was built a new set used for test with 49 structures with several physico-chemical properties, distributed in 22 different families of protein, allowing for a broader test of the algorithm It was conducted a detailed study of the dependence of the genetic algorithm in relation to the distribution of its initial population and it was also investigated ways more efficient and robust to generate the same. Among these, the proposal to distribute the initial population based on the coordinates of individuals of lower energy in the population (proposal 5), it is very promising. This distribution has allowed the algorithm to obtain good results, finding solutions of lower energy in the population very close to experimental structure optimized, without having specific information about the experimental structure. This fact is very important, because the algorithm makes it more realistic in view that in the rational design of drugs, it has not the trial structure. / Os métodos de docking proteína-ligante, são métodos computacionais usados para predizer o modo de ligação de moléculas candidatas a fármaco em seu receptor. O docking permite o teste de centenas de compostos em um curto espaço de tempo, auxiliando na descoberta de novos candidatos a fármacos. A grande complexidade que envolve a ligação do complexo ligante-proteína, torna o problema de docking difícil de ser resolvido computacionalmente. Neste trabalho, são usados os Algoritmos Genéticos, que são uma técnica de otimização baseada na teoria da evolução biológica de Darwin. O algoritmo proposto foi implementado e testado inicialmente por Camila S. de Magalhães em sua tese de doutorado, junto ao Grupo de Modelagem Molecular de Sistemas Biológicos do LNCC, com um conjunto de 5 ligantes de HIV-1 protease. Foi construido um novo conjunto utilizado para teste, agora com 49 estruturas com propriedades físico-químicas diversas, distribuidos em 22 famílias distintas de proteínas, permitindo um teste mais amplo do algoritmo. Foi realizado um estudo aprofundado sobre a dependência do Algoritmo Genético em relação à distribuição da sua população inicial e investigou-se formas mais eficientes e robustas de gerar a mesma. Dentre estas, a proposta de distribuir a população inicial baseada nas coordenadas dos indivíduos de menor energia na população (proposta 5), é muito promissora. Esta distribuição permitiu o algoritmo obter bons resultados, encontrando soluções de menor energia na população muito próximas a estrutura experimental otimizada, sem possuir informações específicas sobre a estrutura experimental. Este fato é muito importante, pois torna o algoritmo mais realista, tendo em vista que no desenho racional de fármacos real não se dispoe da estrutura experimental.
