Title: Strategy Learning and Analysis in RoboCup Soccer Simulation

RoboCup soccer is an international project of robotics and artificial intelligence, which has an ultimate aim of beating a human world champion team by the year 2050. RoboCup soccer simulation is one of the categories in RoboCup soccer where the aspect of artificial intelligence is the main focus. This talk presents some winning approaches to the RoboCup soccer simulation competition using artificial intelligence technique. First, individual strategies are explained. The concept of chain-action is introduced in order to model the decision making process of an agent. Second, team-level strategy analysis is shown where a team strategy is represented using kick trajectories.

Title: Multiclass Support Vector Machine Classifying the Degree of Reinforcement in Construction of a Large-scale Structure

Recently, the declining labor force due to the low birthrate and longevity have been concerns. Since the shortage of labor is also a critical issue in infrastructure development and maintenance, the artificial intelligence (AI) techniques have been introduced to solve the issue. In this paper, we focus on the inspection and checking in constructing structures which have been requiring experiences and skills of experts. First, we formulate the tasks as a recognition problem in which the degree of reinforcement of the structure is classified by exploiting the potential relationships in the data observed in construction sites. In addition, we show a way to resolve inconsistencies in the data. Next, we propose two kinds of multi-class support vector machines (SVMs) which can exploit the relationships in the data. Finally, we evaluate the validity of the formulation and the classification results obtained by applying the proposed SVMs to some real datasets for one kind of large-scale structure.

Title: Uncertainty in Electrical Unit Commitment with Renewable Energy and EV Charging

In this talk, we will show the decision modeling we have been working on national level planning with the Electricity Generating Authority of Thailand (EGAT). Unit Commitment (UC) is the planning process for an electricity power system to provide the supply of electricity from the power generator to meet the forecasted demand. The decisions of the Unit commitment include which units to turn on/off, the energy generated from operating units, and the selection of the fuels. The uncertainty facing in the decision-making process is majorly from the errors of the forecasted demand. There is a fast introduction of renewable energy, especially from the Solar energy. This could bring down the demand and suddenly increase the demand if there is some cloud or rain. Moreover, the Electricity Vehicle (EV) will become major electricity consumption soon. The uncertainty of the charging time and energy could make the electricity system unstable. In addition, the error from forecasted fuel price could affect the decision of the fuel selection or generator unit selection. The integration of these uncertainties into the unit commitment becomes very important. We will discuss the modeling techniques that are suitable for solving the unit commitment with the uncertainty.
