Value generalisation: value correction

Short summary

This post argues that value generalisation is key to AI alignment and demonstrates value correction in a simple RL setting. It introduces a game called 'Humans' where an agent must save humans by drilling through obstacles, with an exploitable 'explode' action that kills humans. The author outlines four stages: in-distribution learning, out-of-distribution reward hacking, value error detection, and value correction back to the true reward.

• •Value generalisation is proposed as necessary and nearly sufficient for AI alignment
• •A simple 'Humans' game illustrates an RL agent detecting and correcting a flawed reward function
• •Methods are purely syntactic — no semantic understanding of situations is assumed
