On the Position Bias of On-Policy Distillation

Yan Xie, Sijie Zhu, Tiansheng Wen +2

On-Policy Distillation (OPD) improves the learning efficiency of standard reinforcement learning through dense, token-level supervision from teachers. In the standard KL objective…

Scaling Attention via Feature Sparsity

Yan Xie, Tiansheng Wen, Tangda Huang +4

Scaling Transformers to ultra-long contexts is bottlenecked by the cost of self-attention. Existing methods reduce this cost along the sequence axis through local window…

Neural collapse in the orthoplex regime

James Alcala, Rayna Andreeva, Vladimir A. Kobzar +4

When training a neural network for classification, the feature vectors of the training set are known to collapse to the vertices of a regular simplex, provided the dimension of…

Discovering Fine-Grained Visual-Concept Relations by Disentangled Optimal Transport Concept Bottleneck Models

Yan Xie, Zequn Zeng, Hao Zhang +5

Concept Bottleneck Models (CBMs) try to make the decision-making process transparent by exploring an intermediate concept space between the input image and the output prediction. E…

HICEScore: A Hierarchical Metric for Image Captioning Evaluation

Zequn Zeng, Jianqiao Sun, Hao Zhang +5

Image captioning evaluation metrics can be divided into two categories, reference-based metrics and reference-free metrics. However, reference-based approaches may struggle to eval…

MeaCap: Memory-Augmented Zero-shot Image Captioning

Zequn Zeng, Yan Xie, Hao Zhang +3

Zero-shot image captioning (IC) without well-paired image-text data can be divided into two categories, training-free and text-only-training. Generally, these two types of methods…
