A new research paper explores the necessity of learning recurrent networks in reinforcement learning (RL) for partially observable environments. The study proposes using a fixed, non-trainable recurrent network combined with a trainable output module, drawing inspiration from reservoir computing principles. Surprisingly, this approach demonstrated competitive performance across various POMDPs, requiring fewer trainable parameters than fully trainable recurrent networks, suggesting that learning the memory module is not always essential for solving such problems.
