Learn Your Own Thoughts: Abstract Token Curriculum

Khashayar Gatmiry, Avrajit Ghosh, Parsa Mirtaheri +4

Large Language Models (LLMs) have achieved remarkable reasoning capabilities by utilizing chain-of-thought (CoT) as a scratchpad for intermediate stages of thinking. However, CoT t…

Hard labels sampled from sparse targets mislead rotation invariant algorithms

Avrajit Ghosh, Bin Yu, Manfred Warmuth +1

One of the most common machine learning setups is logistic regression. In many classification models, including neural networks, the final prediction is obtained by applying a logi…
