Measuring and Mitigating Post-hoc Rationalization in Reverse Chain-of-Thought Generation

ICML 2026poster

Reverse Chain-of-Thought Generation (RCG) synthesizes reasoning traces from query-answer pairs, but runs the risk of producing post-hoc rationalizations: when models can see the answer during generation, the answer serves as a cognitive anchor that shapes the entire explanation. We formalize this ph…

Lock on Target! Precision Unlearning via Directional Control

EMNLP 2025

The unlearning method aims at effectively removing harmful, sensitive, or outdated knowledge without costly retraining the model. However, existing methods suffer from two critical limitations: (1) collateral forgetting, where erasing target data inadvertently removes related but desirable knowledge

Predictive Adversarial Learning from Positive and Unlabeled Data

AAAI 2021technical

This paper studies learning from positive and unlabeled examples, known as PU learning. It proposes a novel PU learning method called Predictive Adversarial Networks (PAN) based on GAN (Generative Adversarial Networks). GAN learns a generator to generate data (e.g., images) to fool a discriminator w…

Translation vs. Dialogue: A Comparative Analysis of Sequence-to-Sequence Modeling

COLING 2020main

Understanding neural models is a major topic of interest in the deep learning community. In this paper, we propose to interpret a general neural model comparatively. Specifically, we study the sequence-to-sequence (Seq2Seq) model in the contexts of two mainstream NLP tasks–machine translation and di…
