UFNRec: Utilizing False Negative Samples for Sequential Recommendation
Xiaoyang Liu, Chong Liu, Pinzheng Wang +5
Sequential recommendation models are primarily optimized to distinguish positive samples from negative ones during training in which negative sampling serves as an essential compon…
Concentration of Random Feature Matrices in High-Dimensions
Zhijun Chen, Hayden Schaeffer, Rachel Ward
The spectra of random feature matrices provide essential information on the conditioning of the linear system used in random feature regression problems and are thus connected to t…
Conditioning of Random Feature Matrices: Double Descent and Generalization Error
Zhijun Chen, Hayden Schaeffer
We provide (high probability) bounds on the condition number of random feature matrices. In particular, we show that if the complexity ratio where is the number o…
CelebA-Spoof Challenge 2020 on Face Anti-Spoofing: Methods and Results
Yuanhan Zhang, Zhenfei Yin, Jing Shao +22
As facial interaction systems are prevalently deployed, security and reliability of these systems become a critical issue, with substantial research efforts devoted. Among them, fa…
Feature Selection with Redundancy-complementariness Dispersion
Zhijun Chen, Chaozhong Wu, Yishi Zhang +4
Feature selection has attracted significant attention in data mining and machine learning in the past decades. Many existing feature selection methods eliminate redundancy by measu…
