Mutual Transfer Learning for Massive Data

no code implementations ICML 2020 Ching-Wei Cheng, Xingye Qiao, Guang Cheng

In this article, we study a new paradigm called mutual transfer learning where among many heterogeneous data domains, every data domain could potentially be the target of interest, and it could also be a useful source to help the learning in other data domains.

Learning Acceptance Regions for Many Classes with Anomaly Detection

no code implementations20 Sep 2022 Zhou Wang, Xingye Qiao

Set-valued classification, a new classification paradigm that aims to identify all the plausible classes that an observation belongs to, can be obtained by learning the acceptance regions for all classes.

Enhanced Nearest Neighbor Classification for Crowdsourcing

no code implementations26 Feb 2022 Jiexin Duan, Xingye Qiao, Guang Cheng

In machine learning, crowdsourcing is an economical way to label a large amount of data.

Statistical Guarantees of Distributed Nearest Neighbor Classification

no code implementations NeurIPS 2020 Jiexin Duan, Xingye Qiao, Guang Cheng

It is interesting to note that the weighted voting scheme allows a larger number of subsamples than the majority voting one.

Covariance-engaged Classification of Sets via Linear Programming

no code implementations26 Jun 2020 Zhao Ren, Sungkyu Jung, Xingye Qiao

The convergence rates of estimation errors and risk of the CLIPS classifier are established to show that having multiple observations in a set leads to faster convergence rates, compared to the standard classification situation in which there is only one observation in the set.

1 code implementation6 Apr 2020 Haomiao Meng, Ying-Qi Zhao, Haoda Fu, Xingye Qiao

These numerical studies have shown the usefulness of the proposed A-ITR framework.

Maximum Entropy Diverse Exploration: Disentangling Maximum Entropy Reinforcement Learning

no code implementations3 Nov 2019 Andrew Cohen, Lei Yu, Xingye Qiao, Xiangrong Tong

A theoretical investigation shows that the set of policies learned by MEDE capture the same modalities as the optimal maximum entropy policy.

Towards Run Time Estimation of the Gaussian Chemistry Code for SEAGrid Science Gateway

no code implementations7 Jun 2019 Angel Beltre, Shehtab Zaman, Kenneth Chiu, Sudhakar Pamidighantam, Xingye Qiao, Madhusudhan Govindaraju

Most codes are not so arbitrary, however, and there has been significant prior research on predicting the run time of applications and workloads.

Diverse Exploration via Conjugate Policies for Policy Gradient Methods

no code implementations10 Feb 2019 Andrew Cohen, Xingye Qiao, Lei Yu, Elliot Way, Xiangrong Tong

We address the challenge of effective exploration while maintaining good performance in policy gradient methods.

Learning Confidence Sets using Support Vector Machines

no code implementations NeurIPS 2018 Wenbo Wang, Xingye Qiao

The goal of confidence-set learning in the binary classification setting is to construct two sets, each with a specific probability guarantee to cover a class.

On Reject and Refine Options in Multicategory Classification

no code implementations9 Jan 2017 Chong Zhang, Wenbo Wang, Xingye Qiao

In many real applications of statistical learning, a decision made from misclassification can be too costly to afford; in this case, a reject option, which defers the decision until further investigation is conducted, is often preferred.

Significance Analysis of High-Dimensional, Low-Sample Size Partially Labeled Data

no code implementations21 Sep 2015 Qiyi Lu, Xingye Qiao

Although both are challenging questions for the high-dimensional, low-sample size data, there has been some recent development for both.

Sparse Fisher's Linear Discriminant Analysis for Partially Labeled Data

no code implementations17 Sep 2015 Qiyi Lu, Xingye Qiao

In many real applications, it is costly to manually place labels on observations; hence it is often that only a small portion of labeled data is available while a large number of observations are left without a label.

Noncrossing Ordinal Classification

no code implementations13 May 2015 Xingye Qiao

We show by simulated and data examples that the proposed method can improve the classification performance for ordinal data without the ambiguity caused by boundary crossings.

Stabilized Nearest Neighbor Classifier and Its Statistical Properties

no code implementations26 May 2014 Wei Sun, Xingye Qiao, Guang Cheng

In this paper, we introduce a general measure of classification instability (CIS) to quantify the sampling variability of the prediction made by a classification method.

Distance-weighted Support Vector Machine

no code implementations11 Oct 2013 Xingye Qiao, Lingsong Zhang

The proposed Distance-weighted Support Vector Machine method can be viewed as a hybrid of SVM and DWD that finds the classification direction by minimizing mainly the DWD loss, and determines the intercept term in the SVM manner.
