4.About awarded research
Discovering the roles of nodes in a network is important for solving various social issues.
Role discovery aims to infer nodes’ roles from a network structure, and it has received considerable attention recently.
The conventional methods of role discovery mainly use unsupervised learning, but due to the lack of information, it is difficult to discover the roles we want or to ascertain the results.
In this paper, we attempt to improve accuracy through using supervised information.
Specifically, we adopt transfer learning using adversarial learning.
As a result of computational experiments, we show that the proposed model discovers a node’s role more effectively than do the conventional methods.
Furthermore, we found that domain-invariant features lead to higher accuracy, the proposed method discovers roles better even with different network sizes, and the proposed method works well even if the networks have nodes of various structures.
5.Your impression & future plan
I am honored to win such a wonderful award.
I will make an effort to improve this research to apply the proposed method to real-world datasets.

Title: Simulation of Strategic Evolution in 5-player Werewolf
Outline of research: This is a study of a simulation of strategy evolution for a 5-player werewolf, one of the regulations of the communication game “WereWolf”.
We proposed a method for finding superior strategies using Bayesian inference, and clarified the non-convergence of strategy evolution.

Title:
Stock Price Analysis Using Combination of Analyst Reports and Several
Documents
Introduction:
Applying natural language processing and neural networks in the context
of analyst reports, we predict stock price movements about excess return
and volatility.
