DENOISER: Rethinking the Robustness for Open-Vocabulary Action Recognition

no code implementations23 Apr 2024 Haozhe Cheng, Cheng Ju, Haicheng Wang, Jinxiang Liu, Mengting Chen, Qiang Hu, Xiaoyun Zhang, Yanfeng Wang

The denoised text classes help OVAR models classify visual samples more accurately; in return, classified visual samples help better denoising.

Extending iLQR method with control delay

no code implementations16 Feb 2020 Cheng Ju, Yan Qin, Chunjiang Fu

Iterative linear quadradic regulator(iLQR) has become a benchmark method to deal with nonlinear stochastic optimal control problem.

Robust inference on the average treatment effect using the outcome highly adaptive lasso

no code implementations18 Jun 2018 Cheng Ju, David Benkeser, Mark J. Van Der Laan

Many estimators of the average effect of a treatment on an outcome require estimation of the propensity score, the outcome regression, or both.

Semisupervised Learning on Heterogeneous Graphs and its Applications to Facebook News Feed

no code implementations18 May 2018 Cheng Ju, James Li, Bram Wasti, Shengbo Guo

We show that the HELP algorithm improves the predictive performance across multiple tasks, together with semantically meaningful embedding that are discriminative for downstream classification or regression tasks.

Collaborative targeted inference from continuously indexed nuisance parameter estimators

no code implementations31 Mar 2018 Cheng Ju, Antoine Chambaz, Mark J. Van Der Laan

Say that the above product is not fast enough and the algorithm for the $G$-component is fine-tuned by a real-valued $h$.

On Adaptive Propensity Score Truncation in Causal Inference

1 code implementation18 Jul 2017 Cheng Ju, Joshua Schwab, Mark J. Van Der Laan

Even if the positivity assumption holds, practical violations of this assumption may jeopardize the finite sample performance of the causal estimator.

Collaborative-controlled LASSO for Constructing Propensity Score-based Estimators in High-Dimensional Data

no code implementations30 Jun 2017 Cheng Ju, Richard Wyss, Jessica M. Franklin, Sebastian Schneeweiss, Jenny Häggström, Mark J. Van Der Laan

Collaborative minimum loss-based estimation (C-TMLE) is a novel methodology for causal inference that takes into account information on the causal parameter of interest when selecting a PS model.

The Relative Performance of Ensemble Methods with Deep Convolutional Neural Networks for Image Classification

1 code implementation5 Apr 2017 Cheng Ju, Aurélien Bibaut, Mark J. Van Der Laan

In this work, we investigated multiple widely used ensemble methods, including unweighted averaging, majority voting, the Bayes Optimal Classifier, and the (discrete) Super Learner, for image recognition tasks, with deep neural networks as candidate algorithms.
