Entropy-Adaptive Fine-Tuning: Resolving Confident Conflicts to Mitigate Forgetting

Muxi Diao, Lele Yang, Wuxuan Gong +6

Supervised Fine-Tuning (SFT) is the standard paradigm for domain adaptation, yet it frequently incurs the cost of catastrophic forgetting. In sharp contrast, on-policy Reinforcemen…

Self-Supervised Learning for Neural Topic Models with Variance-Invariance-Covariance Regularization

Weiran Xu, Kengo Hirami, Koji Eguchi

In our study, we propose a self-supervised neural topic model (NTM) that combines the power of NTMs and regularized self-supervised learning methods to improve performance. NTMs us…
