Parallelized Evolutionary Strategies
When the parallel ES class is declared, I start a pool of workers that then gets sent with a loss function and its inputs to compute whenever calculating gradients.
Started Exploring Count-Based Exploration
I started looking through papers on Exploration and am interested in using the theoretical niceness of Count-based exploration in tabular settings and being able to see their affects in the non-tabular case.
""Unifying Count-Based Exploration and Intrinsic Motivation" creates a model of a arbitrary density model that follows a couple nice properties we would expect of probabilities. Namely, P(S) = N(S) / n
and P'(S) = (N(S) + 1) / (n + 1)
. Where N(S)
represents the number of times you've seen that state, n
represents the total number of states you've seen, and P'(S)
represents the P(S)
after you have seen S
another time. With this model, we are able to solve for N(S)
and derive what the authors call a Psuedo-Count.
