Towards Heterogeneous Clients with Elastic Federated Learning

no code implementations17 Jun 2021 Zichen Ma, Yu Lu, Zihan Lu, Wenye Li, JinFeng Yi, Shuguang Cui

Training in heterogeneous and potentially massive networks introduces bias into the system, which is originated from the non-IID data and the low participation rate in reality.

RevCore: Review-augmented Conversational Recommendation

no code implementations2 Jun 2021 Yu Lu, Junwei Bao, Yan Song, Zichen Ma, Shuguang Cui, Youzheng Wu, Xiaodong He

Existing conversational recommendation (CR) systems usually suffer from insufficient item information when conducted on short dialogue history and unfamiliar items.

RoFormer: Enhanced Transformer with Rotary Position Embedding

9 code implementations20 Apr 2021 Jianlin Su, Yu Lu, Shengfeng Pan, Bo Wen, Yunfeng Liu

We investigate various methods to encode positional information in transformer-based language models and propose a novel implementation named Rotary Position Embedding(RoPE).

Learning Efficient Video Representation with Video Shuffle Networks

no code implementations26 Nov 2019 Pingchuan Ma, Yao Zhou, Yu Lu, Wei zhang

To this end, we propose the video shuffle, a parameter-free plug-in component that efficiently reallocates the inputs of 2D convolution so that its receptive field can be extended to the temporal dimension.

Exact Exponent in Optimal Rates for Crowdsourcing

no code implementations25 May 2016 Chao Gao, Yu Lu, Dengyong Zhou

In many machine learning applications, crowdsourcing has become the primary means for label collection.

Optimal Estimation and Completion of Matrices with Biclustering Structures

no code implementations1 Dec 2015 Chao Gao, Yu Lu, Zongming Ma, Harrison H. Zhou

Biclustering structures in data matrices were first formalized in a seminal paper by John Hartigan (1972) where one seeks to cluster cases and variables simultaneously.
