Matryoshka Language Model Suites

Nathan Godey, Yoav Artzi

Training a language model suite classically requires training each model separately and serving them independently. We improve both training and inference efficiency by stacking su…

Lost in Backpropagation: The LM Head is a Gradient Bottleneck

Nathan Godey, Yoav Artzi

The last layer of neural language models (LMs) projects output features of dimension to logits in dimension , the size of the vocabulary, where usually . This misma…

Co-LMLM: Continuous-Query Limited Memory Language Models

Yair Feldman, Linxi Zhao, Nathan Godey +5

Limited memory language models (LMLMs) externalize factual knowledge during pretraining to a knowledge base (KB), rather than memorizing it in their weights. During generation, the…

The State-Prediction Separation Hypothesis

Giovanni Monea, Nathan Godey, Kianté Brantley +1

Transformers use the same forward computation stream to both predict the next token and store useful state for future token predictions. We formulate the \emph{state-prediction sep…

Biomed-Enriched: A Biomedical Dataset Enriched with LLMs for Pretraining and Extracting Rare and Hidden Content

Rian Touchent, Nathan Godey, Eric de la Clergerie

We introduce Biomed-Enriched, a biomedical text dataset constructed from PubMed via a two-stage annotation process. In the first stage, a large language model annotates 400K paragr…
