Genetic Drift Regularization: on preventing Actor Injection from breaking Evolution Strategies
Here, we highlight the phenomenon of genetic drift where the actor genome and the ES population distribution progressively drift apart, leading to injection having a negative impact on the ES.
Quality with Just Enough Diversity in Evolutionary Policy Search
Evolution Strategies (ES) are effective gradient-free optimization methods that can be competitive with gradient-based approaches for policy search.
Searching Search Spaces: Meta-evolving a Geometric Encoding for Neural Networks
Indirect encoding methods, where each gene can encode for multiple weights, shorten the genome to reduce the dimensions of the search space and better exploit permutations and symmetries.
