Seeking collaborators for scaling and independent evaluation of a new recurrent language model architecture (preprint + code) [R]
Summary
A new recurrent language model architecture, DABSN (Dynamic Adaptive Bias State Network), has been introduced via a preprint and public code (PyTorch, C++, Triton). The initial paper details DABSN's behavior on reasoning, memory, and long-sequence benchmarks like MQAR, Copy, Key-Value retrieval, and A5/60. The developer also trained a 24M parameter language model using 1B pretraining tokens and a GPT-2 tokenizer, yielding promising results. A second paper is planned to focus on language modeling, long-context capabilities, and scaling. The project is open and reproducible, and the developer is actively seeking collaborators for independent reproduction, baseline design, and access to larger GPU clusters to scale the architecture further. DABSN addresses traditional RNN parallelism issues through a diagonal scan, akin to modern state space models.
Key takeaway
For AI researchers or machine learning engineers exploring novel language model architectures, consider evaluating DABSN. Its diagonal scan approach addresses RNN parallelism challenges, potentially offering an alternative to transformer or state space models for long-context tasks. You should investigate its open-source code and contribute to its independent evaluation and scaling efforts, particularly by designing robust benchmarks that test generalization beyond training data and "reach tests" with confounding information.
Key insights
A new recurrent neural network architecture, DABSN, offers parallel processing capabilities similar to state space models, addressing traditional RNN limitations.
