Phase Diagram for Two-layer ReLU Neural Networks at Infinite-width Limit

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

How neural network behaves during the training over different choices of hyperparameters is an important question in the study of neural networks. In ......

Optimal Minimax Variable Selection for Large-Scale Matrix Linear Regression Model

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

Large-scale matrix linear regression models with high-dimensional responses and high dimensional variables have been widely employed in various large-......

Strong Consistency, Graph Laplacians, and the Stochastic Block Model

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

Spectral clustering has become one of the most popular algorithms in data clustering and community detection. We study the performance of classical tw......

Dynamic Tensor Recommender Systems

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

Recommender systems have been extensively used by the entertainment industry, business marketing and the biomedical industry. In addition to its capac......

Integrative High Dimensional Multiple Testing with Heterogeneity under Data Sharing Constraints

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

Identifying informative predictors in a high dimensional regression model is a critical step for association analysis and predictive modeling. Signal ......

Sparse Tensor Additive Regression

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

Tensors are becoming prevalent in modern applications such as medical imaging and digital marketing. In this paper, we propose a sparse tensor additiv......

LocalGAN: Modeling Local Distributions for Adversarial Response Generation

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

This paper presents a new methodology for modeling the local semantic distribution of responses to a given query in the human-conversation corpus, and......

Communication-Efficient Distributed Covariance Sketch, with Application to Distributed PCA

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

A sketch of a large data set captures vital properties of the original data while typically occupying much less space. In this paper, we consider the ......

Bayesian Text Classification and Summarization via A Class-Specified Topic Model

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

We propose the class-specified topic model (CSTM) to deal with the tasks of text classification and class-specific text summarization. The model assum......

Adaptive Estimation of Nonparametric Functionals

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

We provide general adaptive upper bounds for estimating nonparametric functionals based on second-order U-statistics arising from finite-dimensional a......

What Causes the Test Error? Going Beyond Bias-Variance via ANOVA

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

Modern machine learning methods are often overparametrized, allowing adaptation to the data at a fine level. This can seem puzzling; in the worst case......

Projection-free Decentralized Online Learning for Submodular Maximization over Time-Varying Networks

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

This paper considers a decentralized online submodular maximization problem over time-varying networks, where each agent only utilizes its own informa......

Bandit Convex Optimization in Non-stationary Environments

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

Bandit Convex Optimization (BCO) is a fundamental framework for modeling sequential decision-making with partial information, where the only feedback ......

Approximate Newton Methods

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()

Many machine learning models involve solving optimization problems. Thus, it is important to address a large-scale optimization problem in big data ap......

Histogram Transform Ensembles for Large-scale Regression

期刊: JOURNAL OF MACHINE LEARNING RESEARCH, 2021; 22 ()
