Machine-translated · View original
The lab conducts research on computer vision, machine learning, and deep learning.

AboutAbout the lab
Research on AI that understands images and video.
The Kawamoto-Kera Lab studies computer vision, machine learning, and deep learning.
The lab works on techniques that show in a human-understandable form what an AI based its decision on, and on methods for efficiently reusing trained models.
It also studies the robustness of reinforcement learning used for robot control, and the understanding of human actions from video.
The lab belongs to the Information Engineering Course in the Faculty of Engineering, the Graduate School of Science and Engineering, and the Faculty and Graduate School of Information and Data Science, established in fiscal 2024.
Key terms

ResearchResearch themes
The lab studies computer vision, machine learning, and deep learning. It works on explaining AI decisions, reusing trained models, reinforcement learning for control, and recognition of human actions.
*Illustrative imageExplainable AI
The grounds for a deep learning model's decisions tend to remain a black box. The lab aims to develop explanation methods that are theoretically well defined and reproducible, and that show the model's decision process in a form people can understand.
*Illustrative imageTransferring knowledge by adding and subtracting models
The lab studies a framework that extracts the knowledge in a trained model as a difference in parameters and manipulates it by addition and subtraction. This makes it possible to adapt to new tasks and integrate knowledge without large-scale additional training.
*Illustrative imageRobust reinforcement learning for control
In reinforcement learning used to control systems such as legged robots, the lab deliberately adds perturbations to action signals, body shape, and joint characteristics to probe the weaknesses of the learned controller. This serves as a diagnostic tool for building safe and reliable control systems.
*Illustrative imageAction recognition
This research aims to understand human actions from video and skeleton data. By integrating multiple types of data, such as skeleton data and first-person video, and by incorporating language information, the lab aims to make it possible to recognize actions the model has not been trained on.
