ECCV 2022poster

"While the Vision Transformer (VT) architecture is becoming trendy in computer vision, pure VT models perform poorly on tiny datasets. To address this issue, this paper proposes the locality guidance for improving the performance of VTs on tiny datasets. We first analyze that the local information,…

All Tokens Matter: Token Labeling for Training Better Vision Transformers

NeurIPS 2021poster

In this paper, we present token labeling---a new training objective for training high-performance vision transformers (ViTs). Different from the standard training objective of ViTs that computes the classification loss on an additional trainable class token, our proposed one takes advantage of all t…

PnP-DETR: Towards Efficient Visual Analysis With Transformers

ICCV 2021poster

Recently, DETR pioneered the solution of vision tasks with transformers, it directly translates the image feature map into the object detection result. Though effective, translating the full feature map can be costly due to redundant computation on some area like the background. In this work, we enc…

Positive-Negative Momentum: Manipulating Stochastic Gradient Noise to Improve Generalization

ICML 2021spotlight

It is well-known that stochastic gradient noise (SGN) acts as implicit regularization for deep learning and is essentially important for both optimization and generalization of deep networks. Some works attempted to artificially simulate SGN by injecting random noise to improve deep learning. Howeve…

Tokens-to-Token ViT: Training Vision Transformers From Scratch on ImageNet

ICCV 2021poster

Transformers, which are popular for language modeling, have been explored for solving vision tasks recently, e.g., the Vision Transformer (ViT) for image classification. The ViT model splits each image into a sequence of tokens with fixed length and then applies multiple Transformer layers to model…

Central Similarity Quantization for Efficient Image and Video Retrieval

CVPR 2020poster

Existing data-dependent hashing methods usually learn hash functions from pairwise or triplet data relationships, which only capture the data similarity locally, and often suffer from low learning efficiency and low collision rate. In this work, we propose a new global similarity metric, termed as c…

Revisiting Knowledge Distillation via Label Smoothing Regularization

CVPR 2020oral

Knowledge Distillation (KD) aims to distill the knowledge of a cumbersome teacher model into a lightweight student model. Its success is generally attributed to the privileged information on similarities among categories provided by the teacher model, and in this sense, only strong teacher models ar…
