FreeStyle: Free Lunch for Text-guided Style Transfer using Diffusion Models

no code implementations28 Jan 2024 Feihong He, Gang Li, Mengyuan Zhang, Leilei Yan, Lingyu Si, Fanzhang Li

In the decoder, we further modulate features from the dual streams based on a given content image and the corresponding style text prompt for precise style transfer.

On Regularized Sparse Logistic Regression

no code implementations12 Sep 2023 Mengyuan Zhang, Kai Liu

Sparse logistic regression is for classification and feature selection simultaneously.

Strictly Low Rank Constraint Optimization -- An Asymptotically $\mathcal{O}(\frac{1}{t^2})$ Method

no code implementations4 Jul 2023 Mengyuan Zhang, Kai Liu

We study a class of non-convex and non-smooth problems with \textit{rank} regularization to promote sparsity in optimal solution.

Multi-Task Learning with Prior Information

no code implementations4 Jan 2023 Mengyuan Zhang, Kai Liu

Multi-task learning aims to boost the generalization performance of multiple related tasks simultaneously by leveraging information contained in those tasks.

DPOAD: Differentially Private Outsourcing of Anomaly Detection through Iterative Sensitivity Learning

no code implementations27 Jun 2022 Meisam Mohammady, Han Wang, Lingyu Wang, Mengyuan Zhang, Yosr Jarraya, Suryadipta Majumdar, Makan Pourzandi, Mourad Debbabi, Yuan Hong

Outsourcing anomaly detection to third-parties can allow data owners to overcome resource constraints (e. g., in lightweight IoT devices), facilitate collaborative analysis (e. g., under distributed or multi-party scenarios), and benefit from lower costs and specialized expertise (e. g., of Managed Security Service Providers).

Enriched Robust Multi-View Kernel Subspace Clustering

no code implementations21 May 2022 Mengyuan Zhang, Kai Liu

To address the above issues, in this paper we propose a novel Enriched Robust Multi-View Kernel Subspace Clustering framework where the consensus affinity matrix is learned from both multi-view data and spectral clustering.
