Monte Carlo AIXI
While I was visiting Marcus Hutter at ANU a month or so ago, I got talking to one of his students, Joel Veness, who’s working on making computable approximations to AIXI. Joel has a background in writing Go algorithms so … Continue reading
Reinforcement learning in the brain
Model-free reinforcement learning (RL) algorithms are computationally cheap as each state-action pair keeps a cached estimate of its value that can easily be looked up in order to make a decision. Their weakness is that they are not easy to … Continue reading
The unreasonable effectiveness of data
We recently had a visitor to the Gatsby Unit talk about his work in reinforcement learning, in particular the use of planning and forward models to speed up the learning of difficult tasks. The substance of his talk was good, … Continue reading
