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.

Combination of face-to-face classes and remote classes


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.

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
Learn the mathematical theory of inhomogeneous Markov chains. Apply this to a detailed analysis of simulated annealing and genetic algorithms. 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.

Course implementation methods: Combination of face-to-face classes and remote classes

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.

/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 “Signal Processing and Linear System”. Topics include estimation theory, random signal modeling, characterization of stochastic signals and systems, nonparametric estimation, adaptive signal processing, and Kalman filtering.

This course will be conducted remote classes.

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:

* Genetic algorithm (GA).
* Genetic programming (GP).
* Evolutionary programming (EP).
* Memetic algorithm (MA).
* Differential evolution (DE).

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.

Course implementation methods: Remote classes

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.
