Journal ArticleDOI
A data cube model for prediction-based web prefetching
TL;DR: This paper proposes an integrated web-caching and web-prefetching model, where the issues of prefetching aggressiveness, replacement policy and increased network traffic are addressed together in an integrated framework.
Journal ArticleDOI
Robust and Non-Negative Collective Matrix Factorization for Text-to-Image Transfer Learning
TL;DR: This paper proposes a robust and non-negative collective matrix factorization model to handle noise in text-to-image transfer learning, and makes a reliable bridge to transfer accurate and useful knowledge from the text domain to the image domain.
Journal ArticleDOI
Color image restoration by saturation-value total variation
TL;DR: Total variation regularizaton was proposed and employed for the recovery of edges in a grayscale image and its application in color image restoration was approved.
Journal ArticleDOI
Preconditioners for nonsymmetric block toeplitz-like-plus-diagonal linear systems
Zhong-Zhi Bai,Michael K. Ng +1 more
TL;DR: The main contribution is to construct effective preconditioners for this structured coefficient matrix and to derive tight bounds for eigenvalues of the preconditionsed matrices.
Journal ArticleDOI
Customer lifetime value: Stochastic optimization approach
TL;DR: A stochastic dynamic programming model with a Markov chain for the optimization of CLV is proposed and then applied to practical data of a computer service company.
