Semi-supervised segmentation of land cover images using nonlinear canonical correlation analysis with multiple features and t-SNE

no code implementations22 Jan 2024 Hong Wei, James Xiao, Yichao Zhang, Xia Hong

This suggests that, in order to account for spatial correlation between pixels, a feature vector associated with each pixel may be a vectorized tensor representing the multiple bands and a local patch as appropriate.

Continual learning-based probabilistic slow feature analysis for multimode dynamic process monitoring

no code implementations23 Feb 2022 Jingxin Zhang, Donghua Zhou, Maoyin Chen, Xia Hong

In this paper, a novel multimode dynamic process monitoring approach is proposed by extending elastic weight consolidation (EWC) to probabilistic slow feature analysis (PSFA) in order to extract multimode slow features for online monitoring.

Process monitoring based on orthogonal locality preserving projection with maximum likelihood estimation

no code implementations13 Dec 2020 Jingxin Zhang, Maoyin Chen, Hao Chen, Xia Hong, Donghua Zhou

By integrating two powerful methods of density reduction and intrinsic dimensionality estimation, a new data-driven method, referred to as OLPP-MLE (orthogonal locality preserving projection-maximum likelihood estimation), is introduced for process monitoring.

An improved mixture of probabilistic PCA for nonlinear data-driven process monitoring

no code implementations12 Dec 2020 Jingxin Zhang, Hao Chen, Songhang Chen, Xia Hong

To realize this purpose, the technique of a mixture of probabilistic principal component analysers is utilized to establish the model of the underlying nonlinear process with local PPCA models, where a novel composite monitoring statistic is proposed based on the integration of two monitoring statistics in modified PPCA-based fault detection approach.
