授業の概要 ／Course outline |
Computation is one of the most important concepts in computer science, and indicates the limit of the power of computers, which should be familiar to all people working in computer science or engineering field. By this notion, the problems are classified into two classes, that is, the class consisting computable or solvable problems and one consisting incomputable or unsolvable problems. This course provides the notion of computation and computability through several computation models as the rigorous concepts of computation and their equivalence, and the existence of non-computable problems and some concrete examples of non-computable problems. |
授業の目的と到達目標 ／Objectives and attainment goals |
Students can be familiar to the notion of computability defined by several computation models, such as Turing machines, register machines, recursive functions. Furthermore, they can understand the limit of the computers, that is, that there are problems which are not solved by any computer. |

授業の概要 ／Course outline |
Most (if not all) engineering problems can be formulated as optimization problems. To solve optimization problems, different methods have been studied in mathematical programming, operations research, and so on. Conventional methods, however, are usually not efficient enough when the problem space is large and complex. Many problems faced in artificial intelligence are combinatorial optimization problems. These problems are NP-hard, and we may never find polynomial time solutions. To solve these problems efficiently, different "heuristics" have been used to "search for sub-optimal solutions". Heuristics are search methods produced based on human intuition and creative thinking, and are often useful for finding good local solutions quickly in a restricted area. Meta-heuristics are multi-level heuristics that can control the whole process of search, so that global optimal solutions can be obtained systematically and efficiently. Although meta-heuristics cannot always guarantee to obtain the true global optimal solution, they can provide very good results for many practical problems. Usually, meta-heuristics can enhance the computing power of a computer system greatly without increasing the hardware cost. So far many meta-heuristics have been proposed in the literature. In this course, we classify meta-heuristics into two categories. The first one is "single-point" (SP) search, and the second one is "multi-point" (MP) search. For the former, we study tabu search, simulated annealing, iterated local search, and so on. For the latter, we study evolutionary algorithms, including genetic algorithms, genetic programming, evolutionary strategy, and memetic algorithm; ant colony optimization, and particle swarm optimization. Although the efficiency and efficacy of these methods have been proved through experiments, because they were proposed based on human intuition, the theoretic foundation is still weak. Therefore, in this course, we will mainly introduce the basic idea of each method, and try to explain the physical meaning clearly. Mathematical proofs will be introduced very briefly when necessary. |
授業の目的と到達目標 ／Objectives and attainment goals |
In this course, we will study the following topics: (1) Examples of important optimization problems. (2) Conventional optimization methods. (3) Single-point (SP) search methods: * Tabu search. * Simulated annealing. * Iterated local search. * Guided local search. (4) Multi-point (MP) search methods * Genetic algorithm (GA). * Genetic programming (GP). * Evolutionary programming (EP). * Memetic algorithm (MA). * Differential evolution (DE). * Particle swarm optimization (PSO) and ant colony optimization (ACO). After this course, students should be able to (1) Understand the basic ideas of each meta-heuristics algorithm; (2) know how to use meta-heuristics for solving different problems; and (3) become more interested in developing new algorithms. |

A graph, composed of vertices and edges, is one of the most fundamental objects in mathematics. In spite of its simple definition, tons of notions concerning graphs are introduced, and it is sometimes very laborious to perform complete introduction of graph theory. In this class, we first overview graph theory terminology to moderate extent, then we change the focus to carefully selected important topics, and advance our knowledge in that area. For example, we focus on vertex/edge connectivity, and introduce Menger's theorem and Mader's theorem; also focus on spanning trees and Kirchhoff's theorem, etc. Graph theory, as a branch of mathematics, growing its branches like a tree, and even at present, contains many difficult open problems. As another aspect, it has a lot of applications to several areas. Graphs can be used to model many types of relations and processes in physical, biological, social and information systems. This is a reason why graph theory is important for many people in wide areas. |

授業の概要 ／Course outline |
Signal processing is one of the fundamental theories and techniques for constructing modern information systems. During the last half century, many theories and methods have been proposed and widely studied for signal processing. In this core course, first, we review the fundamentals of discrete-time signals and systems. The related content includes the concept and the classification of discrete-time signal, representations of signals in time, frequency, z- and discrete frequency domains, representations and analyses of systems, and filter designs. Then, we focus more on stochastic signals/systems, besides of deterministic signals/systems, which is the main topic of the undergraduate course, “Digital signal processing”. Topics include estimation theory, random signal modeling, characterization of stochastic signals and systems, nonparametric estimation, adaptive signal processing, and Kalman filtering. |
授業の目的と到達目標 ／Objectives and attainment goals |
This course is designed as a fundamental common core course for graduate school students studying in all the fields of information system. It presents a methodology for fundamental signal processing, and then introduce some advance topics, especially statistical features of the signal, and how to apply them for more sophisticated signal processing. Furthermore, the course presents implementation of each method for signal processing with a computer; usually it is performed by Matlab and Python. Finally, the course provides some applications, such as noise canceling, echo canceling, system identification, Kalman filter etc. |

授業の概要 ／Course outline |
The course starts from an overview of evolutionary computation, and a simple example of evolutionary optimization so that the students could quickly grasp the basic ideas of nature-inspired techniques. In the following lectures, design examples in game, learning systems, and intelligent systems will be given. The aim of this course is to let students learn nature-inspired design by examples. |
授業の目的と到達目標 ／Objectives and attainment goals |
1. To know what nature-inspired design techniques are and how they are applied to solve some real world problems. 2. To understand the advantages and disadvantages of nature-inspired design compared to other traditional design techniques. 3. To investigate potential applications of nature-inspired techniques to some real world problems. |
授業スケジュール ／Class schedule |
1. Introduction Give an overview of evolutionary computation, and describe a number of evolutionary algorithms including genetic algorithms, evolutionary programming, evolution strategies, and genetic programming. 2. Basic Design by Evolutionary Optimization Function optimization appears in many applications. An example of developing a fast evolutionary programming is given to explain how to find a research problem, how to develop a new method, and how to evaluate the new method statistically. 3. Game Design by Evolutionary Learning Evolutionary algorithms can be used to learn game-playing strategies without human intervention. Some fundamental questions are discussed, including how to learn a game without any teachers, how well the player can learn, and how well the evolved strategies can generalize. 4. Evolutionary Learning Systems Neural network design is a typical design problem because there is a learning component to it. Both direct encoding representations and indirect encoding representations are introduced in the lectures. An example of designing neural network ensembles will be discussed. 5. Rorobot Rontrollers by Evolvable Systems for Evolvable systems refer to the intelligent systems that can change their architectures and behaviors dynamically and autonomously by interacting with their environments. An example of evolvable system design for a robot controller is given. In this example, reinforcement learning will also be introduced. |

授業の概要 ／Course outline |
The models of computations will be introduced and the term rewriting systems (TRS), as a universal model of computation, and its major properties such as termination and confluence will be discussed. Term rewriting is a branch of theoretical computer science which combines elements of logic, universal algebra, automated theorem proving and functional programming. Its foundation is equational logic. TRS constitutes a Turing- complete computational model which is very close to functional programming. It has applications in Algebra, recursion theory, software engineering and programming languages. In general TRSs apply in any context where efficient methods for reasoning with equations are required. |
授業の目的と到達目標 ／Objectives and attainment goals |

授業の概要 ／Course outline |
We present a self-contained theoretical framework for scaled genetic algorithms with binary encoding which converge asymptotically to global optima in analogy to the simulated annealing algorithm which is also discussed. The scaled genetic algorithm employs multiple-bit mutation, single-cut-point crossover (or other crossover) and power-law scaled proportional fitness selection based upon an arbitrary fitness function. In order to achieve asymptotic convergence to global optima, the mutation and crossover rates have to be annealed to zero in proper fashion, and power-law scaling is used with logarithmic growth in the exponent. A detailed listing of theoretical aspects is presented including prerequisites on inhomogeneous Markov chains. In particular, we focus on: (i) The drive towards uniform populations in a genetic algorithm including the undesired effect of genetic drift. (ii) Weak and strong ergodicity of the inhomogeneous Markov chain describing the probabilistic model for the scaled genetic algorithm. (iii) Convergence to globally optimal solutions. We discuss generalizations and extensions of the core framework presented in this exposition such as other encodings, or other versions of the mutation-crossover operator, in particular, the Vose-Liepins version of mutation-crossover. This refers to work by L.M. Schmitt in [Theoretical Computer Science 259 (2001), 1--61] where similar types of algorithms are considered over an arbitrary-size alphabet, and convergence for arbitrary fitness function under more general conditions is shown. Finally, we present an outlook on further developments of the theory. |
授業の目的と到達目標 ／Objectives and attainment goals |

Use Banach algebra techniques to obtain usable estimates for the behavior of scaled probabilistic algorithms. Show global convergence of such algorithms under certain conditions for implementation. |

授業の概要 ／Course outline |
In this class, we deal with various topics arising from pure and applied mathematics concerning Algebraic Systems and Combinatorics. This year, we focus mainly on the theory of finite fields in the area of Algebraic Systems. The finite field F_q --- a field with finite (q) elements --- was first found by E. Galois, and so it is often called a Galois field GF(q). The structure of F_q as a field is uniquely determined by the number of elements q, and for the existence of F_q, it is necessary and sufficient for q to be a power of a prime p. Beginning with polynomial rings, we overview the following: prime fields, finite polynomial fields, field extensions, splitting fields, structure of finite fields, primitive elements, Frobenius cycles, cyclotomic polynomials, and functions between finite fields. When we consider numbers, they are often supposed to be real or complex numbers. But here, we shall contact with more abstract numbers, rings, and fields, to develop the ability of mathematical and abstract thinking. Finite fields are purely mathematical objects. For example, mathematicians often try to extend or modify the theory over real/complex numbers to the one over finite fields in their researches. Finite fields, however, have many application such as theory of experimental design, codes, and logical circuits, etc, which is the reason why the finite fields are very important objects for both of Scientists and Engineers. |
授業の目的と到達目標 ／Objectives and attainment goals |

授業の概要 ／Course outline |
The goal of the course is to demonstrate the basic approaches to the analysis of stochastic (random) processes and the numerical methods of their simulation. An essential pedagogical point of the course is that the main theoretical constructions are illustrated by “on-line” computer simulations and visualization with Python. The use of Python opens for the students an efficient way to the available numerical libraries (also C & C++ libraries) for simulation and visualization of scientific data. |
授業の目的と到達目標 ／Objectives and attainment goals |
Stochastic behavior is exhibited by a wide variety of systems different in nature and its understanding as well as a certain skill in computer simulation of various linear and nonlinear stochastic processes is essential in many research activities, engineering applications, and statistic analysis. It is expected that in the final phase of the course the students will acquire knowledge about - the main models of stochastic phenomena observed in systems of various nature, - the basic algorithms used in simulating stochastic processes, and gain some skill in - programming stochastic processes, - using Python for scientific simulation visualization. |
