A Logical Pattern Memory Pre-trained Model for Entailment Tree Generation

1 code implementation11 Mar 2024 Li Yuan, Yi Cai, Haopeng Ren, Jiexin Wang

LMPM incorporates an external memory structure to learn and store the latent representations of logical patterns, which aids in generating logically consistent conclusions.

Controllable Preference Optimization: Toward Controllable Multi-Objective Alignment

no code implementations29 Feb 2024 Yiju Guo, Ganqu Cui, Lifan Yuan, Ning Ding, Jiexin Wang, Huimin Chen, Bowen Sun, Ruobing Xie, Jie zhou, Yankai Lin, Zhiyuan Liu, Maosong Sun

In practice, the multifaceted nature of human preferences inadvertently introduces what is known as the "alignment tax" -a compromise where enhancements in alignment within one objective (e. g., harmlessness) can diminish performance in others (e. g., helpfulness).

Domain-adaptive and Subgroup-specific Cascaded Temperature Regression for Out-of-distribution Calibration

no code implementations14 Feb 2024 Jiexin Wang, Jiahao Chen, Bing Su

Although deep neural networks yield high classification accuracy given sufficient training data, their predictions are typically overconfident or under-confident, i. e., the prediction confidences cannot truly reflect the accuracy.
