授業の概要
/Course outline
Artificial intelligence (AI) is a research field that studies how to realize intelligent thinking and behavior using a computing machine. The ultimate goal of AI is to make a machine that can learn, plan, and solve problems autonomously. Although AI has been studied for more than half a century, we still cannot make a machine that is as intelligent as a human in all aspects. However, we do have many successful applications. In some cases, the machine equipped with AI technology can be even more intelligent than us. The Alpha-Go system which defeated the world GO champion is a well-known example. In medical diagnosis and machinery design, different kinds of "expert systems" have been widely used to support the human users. In fact, we human beings are becoming more intelligent (may not be wiser) with the help of these kinds of machines.

The main research topics in AI include: problem solving, reasoning, planning, natural language understanding, computer vision, automatic programming, machine learning, and so on. Of course, these topics are closely related with each other. For example, the knowledge acquired through learning can be used both for problem solving and for reasoning. In fact, the skill for problem solving itself should be acquired through learning. Also, methods for problem solving are useful both for reasoning and planning. Further, both natural language understanding and computer vision can be solved using methods developed in the field of pattern recognition.
授業の目的と到達目標
/Objectives and attainment
goals
In this course, we will study the most fundamental knowledge for understanding AI. Specifically, we will study

(1) Search: Problem formulation and search;
(2) Knowledge representation: Expert system, semantic network, and frame;
(3) Reasoning: Propositional logic, predicate logic, and fuzzy logic;
(4) Learning: Pattern recognition, multilayer neural networks, self-organizing neural networks, and decision tree.

After this course, we should be able to

(1) Know how to use the basic search methods;
(2) Understand the basic methods for problem formulation and knowledge representation;
(3) Understand the basic idea of automatic reasoning;
(4) Know some basic concepts related to pattern recognition and neural networks.


Due to limited time, theoretic proofs and formal notations will be eliminated as far as possible, so that we can get the full picture of AI easily. Students who become interested in AI may study further in the graduate school.

授業の概要
/Course outline
As shown in a proverb "Seeing is believing," images have important roles to communicate each other and to accumulate knowledge for humans. Especially, people can use image processing applications easily because camera device is installed into almost all mobile devices or image processing coprocessor is installed into every computer. Thus, the program of image recognition and understanding is a very important target for business. Image processing is a set of techniques which process or convert image given by cameras and extract novel information such as information recognition and knowledge understanding from these processes.
This class include how to input images to computer, data compression, image process technique such as noise reduction or image condition adjustment, filtering for extracting image feature and recognition and understanding these image features. This class aims to understand image processing by discussing "How to extract novel information from images?" as well as introducing basic image processing techniques.

This course explores the human-computer interface as used in interactive multimedia,
namely the design of realtime computer games.
We feature a project-based, "hands-on" approach, emphasizing creation of self-designed
virtual worlds for CGM: consumer-generated media and UGC: user-generated content.
The main vehicle of expression is "Unity,"
a 3D game engine,
combining segments on CAD (computer-aided design),
game design,
motion graphics,
color, graphical & visual design, texture mapping, sound, music, speech & dialog, as well as software engineering and event handling.
We also use
Photopea, Audacity or WavePad, and GarageBand or Reaper as
support tools for multimedia content creation.
The power of experiential education is leveraged by lessons with an emphasis on practical experimentation,
learning by doing.

Due to the coronavirus situation, some course meetings may be held online, using Zoom to conduct distributed classes, or blended, with both in-person and virtual attendance.
授業の目的と到達目標
/Objectives and attainment
goals
We survey the basics of game design, including human interfaces, including demonstrations and "hands-on" exercises with basics
of multimedia: color models, image capture and compositing, graphic composition and 3D design, texture mapping,
stereography, and audio (including dialog) & musical editing. Students use self-designed
multimodal interfaces authored with object-oriented techniques to tell
stories with virtual characters and cinematography (camera motion and gestures, "camerabatics") for deterministic "machinima" (machine cinema =
computer-generated movies) and to engage users in dynamic environments
such as games and digital interactive story-telling.

成績評価の方法・基準
/Grading method/criteria
Most of the coursework involves lab exercises emphasizing creative applications of digital contents creation tools, highlighting design and invention as much as discovery. Weekly "checkpoint" exercises verify specific skill sets--- including design, drawing and painting, color models and specification, digital compositing (layers, overlays, texture mapping), stereography (anaglyphics, chromastereoscopy), audio editing SFX (sound effects), dialog generated with TTS (text-to-speech) synthesis tools, and DTM for BGM (desk-top music composition for background music)--- progressively accumulating into fully realized virtual worlds, stories, or games. There are also creative studio exercises, occasional quizzes, and exams. The course's annual chromastereoptic art contest is juried, and winning entries are exhibited in a special display in the University library. Student scenarios (plays, movies, & games), highlighting originally created worlds and spaces, composed individually (mid-term) and as teams (end-of-term), are presented to the entire class in special review sessions.

/Course outline
Signals and systems are present in any aspects of our world. The examples of signals are speech, audio, image and video signals in consumer electronics such as TV, PC, and smartphone; vital signs in medical systems; electronic radar waveforms in military equipment. Signal processing is concerned with the representation, transformation and manipulation of signals, and extraction of the significant information contained in signals. For example, we may wish to remove the noise in speech signals to make them clear, or to enhance an image to make it more natural. Signal processing is one of the fundamental theories and techniques to construct modern information systems. During the last century, lots of theories and methods have been proposed and widely studied in signal processing. This course includes the concept of continuous-time and discrete-time signals, representations of signals in time, frequency, and other transform domains, representations and analyses of systems, filter structures and designs.
The course is a prerequisite course for your further studying on other related courses, such as biomedical signal processing, speech processing, image processing, audio and video data compressing, pattern recognition, communication systems and so forth.
授業の目的と到達目標
/Objectives and attainment
goals
This course is to provide students with the foundations and tools of signal processing, particularly the time-invariant system in both continuous and discrete domains. We will mainly study the following topics: signal representation in time domain, Fourier transform, sampling theorem, linear time-invariant system, discrete convolution, z-transform, discrete Fourier transform, and discrete filter design.
After this course, the students should be able to understand how to analyze a given signal or system using various transforms; how to process signals to make them more useful; and how to design a signal processor (digital filter) for a given problem.

The purpose of this course is two-fold: To learn some techniques used for extracting information from acoustic signals and to use acoustic signals to display information. Hearing is arguably the second most important sensory modality and it is sometimes preferable than vision to display and acquire information. For example, a car navigation system delivers guidance using speech, or you verbally ask your mobile phone to dial some number. In this course, we briefly review the main characteristics of sound, audio, and their processing for human-computer interaction.

Note: depending on the COVID-19 pandemic evolution, this course may be offered online.
授業の目的と到達目標
/Objectives and attainment
goals
• Students who approve this course are expected to be able to extract information from acoustic signals that can be used as input for other techniques.
• These students are also expected to be able to use acoustic signals to explore big data.
• Given some application constraints (real-time, computing power, etc.) students at the end of the term should be able to decide which of the presented techniques is best for extracting/displaying data using acoustic signals.

Computational geometry is one of important field of computer science to solve geometric problems. In recent, to solve geometric problem with large data and handle with high-speed processing is required for such as geographic information system (GIS), computational graphics (CG), computer-aided design (CAD), and pattern recognition, robotics, and others.
In the class, students learn about computational geometric concepts in the first half section (Chap.1-6), and learn about information visualization on the premise of various concepts / algorithms in the latter part (Chap.7-13). Finally, in Chap. 14, we discuss examples of the application of these concepts and algorithms.

授業の概要
/Course outline
Understanding natural language by computer is a very important technology for communication between human and machine interaction. Also, our real world has so many documents described by natural language. Therefore, the techniques of natural language processing are bases of the information science for understanding it by computers with extracting meaning and reconstruction sentences.
In this lecture, we learn about the techniques of natural language processing using Python and Natural Language Toolkit (NLTK) to understand and extract the meanings of sentences and reconstruction or search it.
Additionally, we learn the basic techniques of process sentences to apply the other country languages.
授業の目的と到達目標
/Objectives and attainment
goals
In this lesson, exercises are performed using the Natural Language Toolkit available in Python. Explanation of Python grammar, etc. will be done within the lecture.
In the lecture, we explain the basic idea and algorithm of natural language processing. In the exercise, we use actual data to perform parsing of natural language, document clustering, semantic analysis, etc.
Also, we try to construct an easy document search engine with the help of NLTK.
