Mining Interest Trends and Adaptively Assigning SampleWeight for Session-based Recommendation

no code implementations20 Jun 2023 Kai Ouyang, Xianghong Xu, Miaoxin Chen, Zuotong Xie, Hai-Tao Zheng, Shuangyong Song, Yu Zhao

Session-based Recommendation (SR) aims to predict users' next click based on their behavior within a short period, which is crucial for online platforms.

Knowledge Soft Integration for Multimodal Recommendation

no code implementations12 May 2023 Kai Ouyang, Chen Tang, Wenhao Zheng, Xiangjin Xie, Xuanji Xiao, Jian Dong, Hai-Tao Zheng, Zhi Wang

To address this issue, we propose using knowledge soft integration to balance the utilization of multimodal features and the curse of knowledge problem it brings about.

Click-aware Structure Transfer with Sample Weight Assignment for Post-Click Conversion Rate Estimation

no code implementations3 Apr 2023 Kai Ouyang, Wenhao Zheng, Chen Tang, Xuanji Xiao, Hai-Tao Zheng

To tackle this issue, we argue that a trade-off should be achieved between the introduction of large amounts of auxiliary information and the protection of valuable information related to CVR.

SEAM: Searching Transferable Mixed-Precision Quantization Policy through Large Margin Regularization

no code implementations14 Feb 2023 Chen Tang, Kai Ouyang, Zenghao Chai, Yunpeng Bai, Yuan Meng, Zhi Wang, Wenwu Zhu

This general and dataset-independent property makes us search for the MPQ policy over a rather small-scale proxy dataset and then the policy can be directly used to quantize the model trained on a large-scale dataset.

Arbitrary Bit-width Network: A Joint Layer-Wise Quantization and Adaptive Inference Approach

no code implementations21 Apr 2022 Chen Tang, Haoyu Zhai, Kai Ouyang, Zhi Wang, Yifei Zhu, Wenwu Zhu

We propose to feed different data samples with varying quantization schemes to achieve a data-dependent dynamic inference, at a fine-grained layer level.

Mixed-Precision Neural Network Quantization via Learned Layer-wise Importance

1 code implementation16 Mar 2022 Chen Tang, Kai Ouyang, Zhi Wang, Yifei Zhu, YaoWei Wang, Wen Ji, Wenwu Zhu

For example, MPQ search on ResNet18 with our indicators takes only 0. 06 s, which improves time efficiency exponentially compared to iterative search methods.
