Bidirectional Generative Modeling Using Adversarial Gradient Estimation
Xinwei Shen, Tong Zhang, Kani Chen
This paper considers the general -divergence formulation of bidirectional generative modeling, which includes VAE and BiGAN as special cases. We present a new optimization metho…
Curiosity-Driven Recommendation Strategy for Adaptive Learning via Deep Reinforcement Learning
Ruijian Han, Kani Chen, Chunxi Tan
The design of recommendations strategies in the adaptive learning system focuses on utilizing currently available information to provide individual-specific learning instructions f…
Nearly Semiparametric Efficient Estimation of Quantile Regression
Kani Chen, Yuanyuan Lin, Zhanfeng Wang +1
As a competitive alternative to least squares regression, quantile regression is popular in analyzing heterogenous data. For quantile regression model specified for one single quan…
Statistical estimation in the proportional hazards model with risk set sampling
Kani Chen
Thomas' partial likelihood estimator of regression parameters is widely used in the analysis of nested case-control data with Cox's model. This paper proposes a new estimator of th…
