Researchers have developed EGGROLL, a method to make evolution strategies more practical for large language models by using low-rank Gaussian products instead of dense weight perturbations. This approach, while computationally efficient, has geometric implications that can affect stability. The study introduces LOO-ROLL, a leave-one-out estimator that maintains the finite-rank population field and reduces mean squared error in transformer blocks. When tested on the GSM8K benchmark, LOO-ROLL significantly improved accuracy for models up to 8 billion parameters. AI
