MicroNet: Improving Image Recognition With Extremely Low FLOPs

ICCV 2021poster

This paper aims at addressing the problem of substantial performance degradation at extremely low computational cost (e.g. 5M FLOPs on ImageNet classification). We found that two factors, sparse connectivity and dynamic activation function, are effective to improve the accuracy. The former avoids th…

Probabilistic Model Distillation for Semantic Correspondence

CVPR 2021poster

Semantic correspondence is a fundamental problem in computer vision, which aims at establishing dense correspondences across images depicting different instances under the same category. This task is challenging due to large intra-class variations and a severe lack of ground truth. A popular solutio…

Revisiting Dynamic Convolution via Matrix Decomposition

ICLR 2021poster

Recent research in dynamic convolution shows substantial performance boost for efficient CNNs, due to the adaptive aggregation of K static convolution kernels. It has two limitations: (a) it increases the number of convolutional weights by K-times, and (b) the joint optimization of dynamic attention…

SEED: Self-supervised Distillation For Visual Representation

ICLR 2021poster

This paper is concerned with self-supervised learning for small models. The problem is motivated by our empirical studies that while the widely used contrastive self-supervised learning method has shown great progress on large model training, it does not work well for small models. To address this p…

Stronger NAS with Weaker Predictors

NeurIPS 2021poster

Neural Architecture Search (NAS) often trains and evaluates a large number of architectures. Recent predictor-based NAS approaches attempt to alleviate such heavy computation costs with two key steps: sampling some architecture-performance pairs and fitting a proxy accuracy predictor. Given limited…

VALUE: A Multi-Task Benchmark for Video-and-Language Understanding Evaluation

NeurIPS 2021poster

Most existing video-and-language (VidL) research focuses on a single dataset, or multiple datasets of a single task. In reality, a truly useful VidL system is expected to be easily generalizable to diverse tasks, domains, and datasets. To facilitate the evaluation of such systems, we introduce Video…

VIVO: Visual Vocabulary Pre-Training for Novel Object Captioning

AAAI 2021technical

It is highly desirable yet challenging to generate image captions that can describe novel objects which are unseen in caption-labeled training data, a capability that is evaluated in the novel object captioning challenge (nocaps). In this challenge, no additional image-caption training data, other t…

Dynamic Convolution: Attention Over Convolution Kernels

CVPR 2020oral

Light-weight convolutional neural networks (CNNs) suffer performance degradation as their low computational budgets constrain both the depth (number of convolution layers) and the width (number of channels) of CNNs, resulting in limited representation capability. To address this issue, we present Dy…

Rethinking Classification and Localization for Object Detection

CVPR 2020poster

Two head structures (i.e. fully connected head and convolution head) have been widely used in R-CNN based detectors for classification and localization tasks. However, there is a lack of understanding of how does these two head structures work for these two tasks. To address this issue, we perform a…

Reinforced Temporal Attention and Split-Rate Transfer for Depth-Based Person Re-Identification

ECCV 2018poster

We address the problem of person re-identification from commodity depth sensors. One challenge for depth-based recognition is data scarcity. Our first contribution addresses this problem by introducing split-rate RGB-to-Depth transfer, which leverages large RGB datasets more effectively than popular…
