Hiroshi Nonaka

Aspiring PhD Student in Machine Learning

Hi! 👋 I'm Hiroshi (博志), an aspiring PhD student in machine learning, particularly in representation learning, interpretability of LLMs, VLMs, and model-based RL, and the science of deep learning.

This fall, I am researching the mechanistic interpretability and moral reasoning of LLMs at Relational Cognition Lab at University of California, Irvine. Previously, I researched model-free RL at the University of Maryland, College Park (NeurIPS 2025 ARLET Workshop), narrative representations of LLMs at Soka University of America (NeurIPS 2025 LLM-Evaluation Workshop), VLMs for emotion recognition at Texas State University (IEEE UEMCON 2024), and spatiotemporal understanding in model-based RL under the University of Tokyo.
