In this case, enforcing diversity could be counterproductive. While mode collapse is rare, as discussed above, its possibility decreases the robustness of a direct CL integration. Leveraging the insights from this section, a lenient Selective Memory Purge (allowing a larger number of identical scaffolds to be sampled before penalization) can be applied on top of CL to retain Augmented Memory's sample efficiency while also capitalizing on benefits of CL.
