NTT Research has launched the Physics of Artificial Intelligence Group to address the 'black box' challenge of AI.Led by Dr. Hidenori Tanaka, the group aims to understand the internal mechanisms of AI and bridge the trust gap between AI systems and human users.The group's mission includes creating experimentally controllable learning environments for AI inspired by physics methodologies.NTT Research's previous work includes neural network pruning, bias-removal techniques, and studies into AI's conceptual understanding.
