The Why and How of Convex Clustering
Eric C. Chi, Aaron J. Molstad, Zheming Gao +1
This survey reviews a clustering method based on solving a convex optimization problem. Despite the plethora of existing clustering methods, convex clustering has several uncommon…
A Novel Markov Model for Near-Term Railway Delay Prediction
Jin Xu, Weiqi Wang, Zheming Gao +2
Predicting the near-future delay with accuracy for trains is momentous for railway operations and passengers' traveling experience. This work aims to design prediction models for t…
Sparse Universum Quadratic Surface Support Vector Machine Models for Binary Classification
Hossein Moosaei, Ahmad Mousavi, Milan Hladík +1
In binary classification, kernel-free linear or quadratic support vector machines are proposed to avoid dealing with difficulties such as finding appropriate kernel functions or tu…
Quadratic Surface Support Vector Machine with L1 Norm Regularization
Ahmad Mousavi, Zheming Gao, Lanshan Han +1
We propose norm regularized quadratic surface support vector machine models for binary classification in supervised learning. We establish their desired theoretical proper…
Rescaled Pure Greedy Algorithm for Convex Optimization
Zheming Gao, Guergana Petrova
We suggest a new greedy strategy for convex optimization in Banach spaces and prove its convergent rates under a suitable behavior of the modulus of uniform smoothness of the objec…
