Spatial modeling of brain tissue
John, Pavel ; Neruda, Roman (advisor) ; Brom, Cyril (referee)
Neural connections in the human brain are known to be modified by experiences. Yet, little is known about the mechanism of the modification and its implications on the brain function. The aim of this thesis is to investigate what impact the spatial properties of brain tissue can have on learning and memory. In particular, we focus on the dendritic plasticity. We present a model where the tissue is represented by a two-dimensional grid and its structure is characterized by various connections between the grid cells. We provide a formal definition of the model and we prove it to be computational as strong as the Turing machine. An adaptation algorithm proposed enables the model to reflect the environmental feedback, while evolutionary algorithms are employed to search for a satisfactory architecture of the model. Implementation is provided and several experiments are driven to demonstrate the key properties of the model. Powered by TCPDF (www.tcpdf.org)

Metaphors in Partners' Calling
Štěpánová, Pavla ; Janovec, Ladislav (advisor) ; Chejnová, Pavla (referee)
Diploma thesis Figurativeness of denominations in a partnership based on a questionnare survey deals with a discourse of figurative denominations in partnerhips. Firstly, the position of partnership denominations within the field of onomastics is defined and a general language characteristics of these denomations is presented. Further on, the main ideas from cognitive linguistics are presented, especially the conceptual metaphor theory which has been the basis for an analysis and interpretation of partnership denominations. These have been divided into several semantical groups in the context of which the partnership denominations are being analysed.

Meaning of cognitive processes for creating artificial intelligence
Pangrác, Vojtěch ; Pstružina, Karel (advisor) ; Burian, Jan (referee)
This work is aimed at creating a single view in the field of cognitive processes. Namely it is analysis of providing importance of cognitive processes for the entire field of artificial intelligence. The whole area of cognitive processes is described through the analysis of biological cognitive processes and their subsequent comparison with the processes of artificial intelligence and also the overall analysis of their limitations and their use. The work also contains a brief overview of the architecture of artificial intelligence and philosophical essay focused on the relationship of mind and body. In the end we present a project from IBM workshop, which is very important for their ability to work with natural language and understanding the content of questions asked.

Meaning of cognitive processes for creating artificial intelligence
Smutný, Zdeněk ; Pstružina, Karel (advisor) ; Kelemen, Jozef (referee)
This diploma thesis brings an integral view at cognitive processes connected with artificial intelligence systems, and makes a comparison with the processes observed in nature, including human being. A historical background helps us to look at the whole issue from a certain point of view. The main axis of interest comes after the historical overview and includes the following: environment -- stimulations -- processing -- reflection in the cognitive system -- reaction to stimulation; I balance the approach and the limited potential of the human being against the machine (or artificial intelligence). In the last part, there are introduced two projects that have been already implemented in the inteligent transport systems, and their potential for the further expansion and development is shown here. The main emphasis is placed on the coherence between each part of this thesis and cognitive processes, and on the relation and the mutual dependence of these processes.

Design of an e-learning solution for the course 5FI404 – Cognitive Science
Klička, Lukáš ; Šubrta, Václav (advisor) ; Sigmund, Tomáš (referee)
This paper presents an e-learning solution used as supporting educational material for the subject 5FI404 - "Cognitive Science". In the theoretical part it summarizes the basic knowledge and principles from the field of e-learning and e-learning course design, which it then attempts to practically apply to the author's own e-learning solution. The first half of the paper focuses on theoretical aspects of planning of an e-learning course, its presentation to the user, user interface design and the possibility of using it to review learnt information. Principles used in individual chapters are discussed in detail so that their application in the practical part is understandable. The second half of this paper focuses on the author's own e-learning solution. The author presents an e-learning course meant to serve as support material for the subject "Cognitive science" at the University of Economics in Prague. Finally, the author analyzes the benefits of his solution and the possibilities of its practical application.

Cognitive biases in decision making process
Trejbal, Pavel ; Pstružina, Karel (advisor) ; Jirků, Petr (referee)
The focus of this thesis is mainly on the area of human decision making. During the decision process we are subjected to several influences, which bias our judgement. Therefore, we may be misguided towards wrong decisions. In addition, it is important that the display of distorted influence is regularly repeated with the same persons. Thus, we may assume that we are talking about a universal apparatus of the human mind. The aim of this thesis is also to identify the above-mentioned influences, and mainly to understand the nature of their origin. The knowledge resulting from the research could become important and useful tool for the reader, since the knowledge may be used for the improvement of our own decisions in both private and professional life. The research is based on interdisciplinary approaches to cognitive science. On one hand we use the functional model of mind, on the other hand we utilize a wide range of empirical data from several fields, such as psychology, behavioral economics and the sciences concerned with the brain. Using these tools, we analyze specific influences, which are considered to be important from the point of view of decision making. They are for example feelings, emotions, social influences, language, self, experience, expectations and prior forms of judgement. Based on the analysis of the influences, hypotheses about their interconnectedness are deduced. Finally, we suggest several practical methods, which should help us to improve our own decision making and help us to avoid wrong conclusions.

User interface in view of cognitive science
Šilar, Pavel ; Sigmund, Tomáš (advisor) ; Bruckner, Tomáš (referee)
User interfaces of operating systems were often developed according to technological and marketing restrictions. Recently, more emphasis is aimed on the user who uses the operating system. User interfaces, which correspond to user's behavior and expectations, are designed. Cognitive science commits itself in the research of a human mind phenomenon. Its base was used to settle aspects of a human thinking which are related to a user interface and its functionality. It is mainly area of UI design, text elements and functions. Overall model of the user interface was established following recognized conclusions. This model was used to verify, if existing operating systems correspond to findings about the human mind. Correspondence among operating systems and cognitive science was recognized during the comparison of existing operating systems and the created model. Also some insufficiencies were identified, mainly in the area of stereometric design, using of gestalt principles, support of a user's training and involving learning methods of the artificial intelligence. Design of the user interface can be improved in these four areas to ensure better coherency with the human mind.
