Out-of-distribution generalization via composition: a lens through induction heads in Transformers

1 code implementation18 Aug 2024 Jiajun Song, Zhuoyan Xu, Yiqiao Zhong

We empirically examined the training dynamics of Transformers on a synthetic example and conducted extensive experiments on a variety of pretrained LLMs, focusing on a type of components known as induction heads.

Conv-Basis: A New Paradigm for Efficient Attention Inference and Gradient Computation in Transformers

no code implementations8 May 2024 YIngyu Liang, Heshan Liu, Zhenmei Shi, Zhao Song, Zhuoyan Xu, Junze Yin

We then design a fast algorithm to approximate the attention matrix via a sum of such $k$ convolution matrices.

Towards Few-Shot Adaptation of Foundation Models via Multitask Finetuning

1 code implementation22 Feb 2024 Zhuoyan Xu, Zhenmei Shi, Junyi Wei, Fangzhou Mu, Yin Li, YIngyu Liang

An emerging solution with recent success in vision and NLP involves finetuning a foundation model on a selection of relevant tasks, before its adaptation to a target task with limited labeled samples.
