Reliable Adaptive Vision Research

I work on reliable, adaptive, and deployment-aware computer vision systems for real-world autonomy.

I am an AI researcher at Honda R&D Japan and a PhD student at The University of Tokyo. My research focuses on adaptive and reliable vision systems, including test-time adaptation, continual and long-tailed learning, CLIP/VLM adaptation, and robust perception for AD/ADAS. I am especially interested in methods that remain reliable under distribution shift, class imbalance, and real-world deployment constraints.

Research Interests

Adaptive Vision under Distribution Shift

Test-time adaptation, domain shift, calibration, robustness, and reliable model behavior at deployment.

Continual and Long-Tailed Learning

Class-incremental learning, long-tailed continual learning, adaptive priors, and imbalance-aware recognition.

CLIP / VLM Adaptation

Training-free and lightweight adaptation of vision-language models, label propagation, graph-based adaptation, and robust open-vocabulary recognition.

Robust AD/ADAS Perception

Multi-camera perception, free-space and road segmentation, temporal consistency, long-tail driving conditions, lightweight deployment, and edge-aware perception systems.
