## Summary

Rohan Paul shares a post introducing RL with Neural Feedback (RLNF), which trains AI models to respond to human preferences using brain signals. The post says an image model adjusts a face toward what the viewer finds more attractive, without ratings, clicks or prompts. An attached chart, citing Arshamian et al. 2022, shows how personal preferences are across landscape scenes, faces, odours, voices and abstract art.

RL with Neural Feedback (RLNF)

An AI image model learns what you personally find attractive by reading your brain’s reaction as you look, then changes the picture to score higher, with no ratings, clicks or prompts from you.
