Exploring Quantization for Efficient Pre-Training of Transformer Language Models

EMNLP 2024finding

The increasing scale of Transformer models has led to an increase in their pre-training computational requirements. While quantization has proven to be effective after pre-training and during fine-tuning, applying quantization in Transformers during pre-training has remained largely unexplored at sc…

Lookbehind-SAM: k steps back, 1 step forward

ICML 2024poster

Sharpness-aware minimization (SAM) methods have gained increasing popularity by formulating the problem of minimizing both loss value and loss sharpness as a minimax objective. In this work, we increase the efficiency of the maximization and minimization parts of SAM's objective to achieve a better…

Why Don’t Prompt-Based Fairness Metrics Correlate?

ACL 2024long

The widespread use of large language models has brought up essential questions about the potential biases these models might learn. This led to the development of several metrics aimed at evaluating and mitigating these biases. In this paper, we first demonstrate that prompt-based fairness metrics e…
