Researchers have developed a new training method called ReFINE (Reinforced Fast weIghts via Next sEquence prediction) to improve long-context modeling in fast weight architectures. This method addresses a mismatch between how these models are typically trained using next-token prediction and their reliance on evolving memory states. ReFINE employs next-sequence prediction, a sequence-level objective that trains models to generate coherent multi-token continuations. Experiments on LaCT-760M and DeltaNet-1.3B models demonstrated that ReFINE outperforms standard supervised fine-tuning on tasks like needle-in-a-haystack retrieval and long-context question answering, as well as on the LongBench benchmark.
