ORPO: Monolithic Preference Optimization without Reference Model

2 code implementations12 Mar 2024 Jiwoo Hong, Noah Lee, James Thorne

While recent preference alignment algorithms for language models have demonstrated promising results, supervised fine-tuning (SFT) remains imperative for achieving successful convergence.

Disentangling Structure and Style: Political Bias Detection in News by Inducing Document Hierarchy

no code implementations5 Apr 2023 Jiwoo Hong, Yejin Cho, Jaemin Jung, Jiyoung Han, James Thorne

Our approach overcomes this limitation by considering both the sentence-level semantics and the document-level rhetorical structure, resulting in a more robust and style-agnostic approach to detecting political bias in news articles.

Activation Sharing with Asymmetric Paths Solves Weight Transport Problem without Bidirectional Connection

no code implementations NeurIPS 2021 Sunghyeon Woo, Jeongwoo Park, Jiwoo Hong, Dongsuk Jeon

One of the reasons why it is difficult for the brain to perform backpropagation (BP) is the weight transport problem, which argues forward and feedback neurons cannot share the same synaptic weights during learning in biological neural networks.
