New LLM Pretraining Method Boosts Performance on Knowledge and Math Tasks

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called LARE (Loss-Adaptive Reweighting under fixed Exposure) to improve the pretraining of large language models. This technique adjusts the influence of different data domains on learning by reweighting their contribution based on running loss statistics, rather than altering the amount of data exposed. Experiments with a 1.5B parameter model trained on 240B tokens showed significant gains across knowledge, mathematics, and code benchmarks, including a notable improvement of +17.06 pp on GSM8K. LARE demonstrates that optimizing domain loss scales can enhance joint capabilities without requiring additional data exposure. AI

IMPACT This method could lead to more efficient and effective LLM training, improving performance on specialized tasks without increasing data exposure.

    Beyond Data Schedule: Fast LLM Pretraining on Data Mixtures by Loss-Reweighting

    arXiv:2610.32141v1 Announce Type: cross Abstract: Large language models often acquire specialized capabilities through successive pretraining stages, but these gains can come at the cost of forgetting earlier knowledge. In this work, we investigate whether such trade-offs can be …
