How to Train Data-Efficient LLMs

Noveen Sachdeva, Benjamin Coleman, Wang-Cheng Kang +6

The training of large language models (LLMs) is expensive. In this paper, we study data-efficient approaches for pre-training LLMs, i.e., techniques that aim to optimize the Pareto…

Farzi Data: Autoregressive Data Distillation

Noveen Sachdeva, Zexue He, Wang-Cheng Kang +3

We study data distillation for auto-regressive machine learning tasks, where the input and output have a strict left-to-right causal structure. More specifically, we propose Farzi,…

Exploring Dual Encoder Architectures for Question Answering

Zhe Dong, Jianmo Ni, Daniel M. Bikel +4

Dual encoders have been used for question-answering (QA) and information retrieval (IR) tasks with good results. Previous research focuses on two major types of dual encoders, Siam…

Scaling Up Models and Data with and

Adam Roberts, Hyung Won Chung, Anselm Levskaya +40

Recent neural network-based language models have benefited greatly from scaling up the size of training datasets and the number of parameters in the models themselves. Scaling can…

Transformer Memory as a Differentiable Search Index

Yi Tay, Vinh Q. Tran, Mostafa Dehghani +10

In this paper, we demonstrate that information retrieval can be accomplished with a single Transformer, in which all information about the corpus is encoded in the parameters of th…

Large Dual Encoders Are Generalizable Retrievers

Jianmo Ni, Chen Qu, Jing Lu +8

It has been shown that dual encoders trained on one domain often fail to generalize to other domains for retrieval tasks. One widespread belief is that the bottleneck layer of a du…

LongT5: Efficient Text-To-Text Transformer for Long Sequences

Mandy Guo, Joshua Ainslie, David Uthus +4

Recent work has shown that either (1) increasing the input length or (2) increasing model size can improve the performance of Transformer-based neural models. In this paper, we pre…
