EgoViT: Pyramid Video Transformer for Egocentric Action Recognition

no code implementations15 Mar 2023 Chenbin Pan, Zhiqi Zhang, Senem Velipasalar, Yi Xu

Different from previous video transformers, which use the same static embedding as the class token for diverse inputs, we propose a dynamic class token generator that produces a class token for each input video by analyzing the hand-object interaction and the related motion information.

CLIP-FLow: Contrastive Learning by semi-supervised Iterative Pseudo labeling for Optical Flow Estimation

no code implementations25 Oct 2022 Zhiqi Zhang, Nitin Bansal, Changjiang Cai, Pan Ji, Qingan Yan, Xiangyu Xu, Yi Xu

To this end, we propose CLIP-FLow, a semi-supervised iterative pseudo-labeling framework to transfer the pretraining knowledge to the target real domain.

MKANet: A Lightweight Network with Sobel Boundary Loss for Efficient Land-cover Classification of Satellite Remote Sensing Imagery

no code implementations28 Jul 2022 Zhiqi Zhang, Wen Lu, Jinshan Cao, Guangqi Xie

Limited by hardware computational resources and memory capacity, most existing studies preprocessed original remote sensing images by down sampling or cropping them into small patches less than 512*512 pixels before sending them to a deep neural network.

Label prompt for multi-label text classification

no code implementations18 Jun 2021 Rui Song, Xingbing Chen, Zelong Liu, Haining An, Zhiqi Zhang, Xiaoguang Wang, Hao Xu

In this paper, we propose a Label Mask multi-label text classification model (LM-MTC), which is inspired by the idea of cloze questions of language model.

FiBiNET: Combining Feature Importance and Bilinear feature Interaction for Click-Through Rate Prediction

31 code implementations23 May 2019 Tongwen Huang, Zhiqi Zhang, Junlin Zhang

In this paper, a new model named FiBiNET as an abbreviation for Feature Importance and Bilinear feature Interaction NETwork is proposed to dynamically learn the feature importance and fine-grained feature interactions.

FAT-DeepFFM: Field Attentive Deep Field-aware Factorization Machine

12 code implementations15 May 2019 Junlin Zhang, Tongwen Huang, Zhiqi Zhang

Although some CTR model such as Attentional Factorization Machine (AFM) has been proposed to model the weight of second order interaction features, we posit the evaluation of feature importance before explicit feature interaction procedure is also important for CTR prediction tasks because the model can learn to selectively highlight the informative features and suppress less useful ones if the task has many input features.
