SteerLM: Attribute Conditioned SFT as an (User-Steerable) Alternative to RLHF

no code implementations9 Oct 2023 Yi Dong, Zhilin Wang, Makesh Narsimhan Sreedhar, Xianchao Wu, Oleksii Kuchaiev

Model alignment with human preferences is an essential step in making Large Language Models (LLMs) helpful and consistent with human values.


Retrieval meets Long Context Large Language Models

no code implementations4 Oct 2023 Peng Xu, Wei Ping, Xianchao Wu, Lawrence McAfee, Chen Zhu, Zihan Liu, Sandeep Subramanian, Evelina Bakhturina, Mohammad Shoeybi, Bryan Catanzaro

Perhaps surprisingly, we find that LLM with 4K context window using simple retrieval-augmentation at generation can achieve comparable performance to finetuned LLM with 16K context window via positional interpolation on long context tasks, while taking much less computation.

Machine Reading Comprehension with Enhanced Linguistic Verifiers

no code implementations1 Jan 2021 Xianchao Wu

We propose two linguistic verifiers for span-extraction style machine reading comprehension to respectively tackle two challenges: how to evaluate the syntactic completeness of predicted answers and how to utilize the rich context of long documents.

Dialog Generation Using Multi-Turn Reasoning Neural Networks

no code implementations NAACL 2018 Xianchao Wu, Ander Mart{\'\i}nez, Momo Klyen

In this paper, we propose a generalizable dialog generation approach that adapts multi-turn reasoning, one recent advancement in the field of document comprehension, to generate responses ({``}answers{''}) by taking current conversation session context as a {``}document{''} and current query as a {``}question{''}.
