Provable Guarantees for Sparsity Recovery with Deterministic Missing Data Patterns

no code implementations10 Jun 2022 Chuyang Ke, Jean Honorio

We study the problem of consistently recovering the sparsity pattern of a regression parameter vector from correlated observations governed by deterministic missing data patterns using Lasso.

Dual Convexified Convolutional Neural Networks

no code implementations27 May 2022 Site Bai, Chuyang Ke, Jean Honorio

To overcome this, we propose a highly novel weight recovery algorithm, which takes the dual solution and the kernel information as the input, and recovers the linear weight and the output of convolutional layer, instead of weight parameter.

Federated Myopic Community Detection with One-shot Communication

no code implementations14 Jun 2021 Chuyang Ke, Jean Honorio

We provide an efficient algorithm, which computes a consensus signed weighted graph from clients evidence, and recovers the underlying network structure in the central server.

A Thorough View of Exact Inference in Graphs from the Degree-4 Sum-of-Squares Hierarchy

no code implementations16 Feb 2021 Kevin Bello, Chuyang Ke, Jean Honorio

Performing inference in graphs is a common task within several machine learning problems, e. g., image segmentation, community detection, among others.

Information Theoretic Limits of Exact Recovery in Sub-hypergraph Models for Community Detection

no code implementations29 Jan 2021 Jiajun Liang, Chuyang Ke, Jean Honorio

Our bounds are tight and pertain to the community detection problems in various models such as the planted hypergraph stochastic block model, the planted densest sub-hypergraph model, and the planted multipartite hypergraph model.

Exact Inference with Latent Variables in an Arbitrary Domain

no code implementations28 Jan 2019 Chuyang Ke, Jean Honorio

We analyze the necessary and sufficient conditions for exact inference of a latent model.

Information-theoretic Limits for Community Detection in Network Models

no code implementations NeurIPS 2018 Chuyang Ke, Jean Honorio

For the Latent Space Model, the non-recoverability condition depends on the dimension of the latent space, and how far and spread are the communities in the latent space.

On The Projection Operator to A Three-view Cardinality Constrained Set

no code implementations ICML 2017 Haichuan Yang, Shupeng Gui, Chuyang Ke, Daniel Stefankovic, Ryohei Fujimaki, Ji Liu

The cardinality constraint is an intrinsic way to restrict the solution structure in many domains, for example, sparse learning, feature selection, and compressed sensing.

Prognostics of Surgical Site Infections using Dynamic Health Data

no code implementations12 Nov 2016 Chuyang Ke, Yan Jin, Heather Evans, Bill Lober, Xiaoning Qian, Ji Liu, Shuai Huang

Since existing prediction models of SSI have quite limited capacity to utilize the evolving clinical data, we develop the corresponding solution to equip these mHealth tools with decision-making capabilities for SSI prediction with a seamless assembly of several machine learning models to tackle the analytic challenges arising from the spatial-temporal data.
