The authors call this family "generalized state space models" (GSSMs). It includes S4, Mamba, LSTMs and linear-attention variants. The authors find that the main loss is the ability to reproduce or retrieve arbitrary parts… 2. **[Echo Chamber: RL Post-training Amplifies Behaviors Learned in Pretraining](https://md.research.elamur.ai/free/en/papers/zhao-2025-echo-chamber-rl-post-training/)** *(2025 · 34 citations)* The paper asks why reinforcement-learning fine-tuning improves mathematical reasoning in language models. Pretraining data for popular base models such as Qwen is usually undisclosed, which makes it hard to separate the effect of RL from the effect of pretraining. To get around this, the authors train decoder-only… 3. **[Transcendence: Generative Models Can Outperform The Experts That Train Them](https://md.research.elamur.ai/free/en/papers/zhang-2024-transcendence-generative-models-outperform-experts/)** *(2024 · 12 citations)* Models trained with cross-entropy learn to mimic the distribution of their training data. This suggests they cannot outperform the humans who produced that data. The authors examine this assumption and define "transcendence" as a generative model earning higher reward than every expert behind its training set. ## All works 5 works of theirs in our library, the most cited first; 3 with a page here, the others link their original until we summarise them. 1.
