Yusuke Hayashi
Independent researcher — computational cognitive science & collective intelligence
I study how symbols, meaning, and agreement emerge in populations of learning agents — and how the same mathematics can help humans and machines deliberate together.
Research
Collective Predictive Coding (CPC)
Free-energy accounts of symbol emergence in multi-agent systems; phase transitions in shared representations.
Symbol emergence & emergent communication
Lewis games, VQ world models, and the information-theoretic limits of shared codes.
AI alignment
Alignment as collective inference: what agreement between humans and models must preserve, and what it may compress away.
Digital democracy
Deliberation platforms (Polis-style) as collective world models; mapping high-dimensional opinion spaces.
