Joint dictionary learning
NettetJointly Learning Structured Analysis Discriminative Dictionary and Analysis Multiclass Classifier Zhao Zhang, Member, IEEE, Weiming Jiang , Jie Qin, Li Zhang, Member, IEEE, Fanzhang Li , Min Zhang, and Shuicheng Yan, Fellow, IEEE Abstract— In this paper, we propose an analysis mechanism based structured Analysis Discriminative Dictionary … NettetIn this paper, we propose a weakly coupled and geometry co-regularized joint dictionary learning method to address the problem of cross-modality synthesis while considering the fact that collecting the large amounts of training data is often impractical. Our learning stage requires only a few registered multi-modality image pairs as training …

When signals are not sparse themselves, but can be jointly sparsely represented in some basis, we propose a joint dictionary learning algorithm that learns dictionaries in which the joint sparsity is … Nettet1. des. 2024 · M is restrained to distribute closely to identity matrix in the positive semi-definite cone. After each iteration, we need to project M onto the positive semi-definite …

The key idea is to learn dictionary patterns of short evolution instances of the new daily cases in multiple countries at the same time, so that their latent … Nettet7. jan. 2024 · Building on the K-SVD technique, our proposed joint dictionary learning frameworks aim to maximize the expressive power by optimizing simultaneously a pair …
Nettetto learn two dictionaries at the same time, previous algo-rithms [24, 26] use the same coefficients for both dictio-naries, i.e., α(x) i = α (y) i. In this way, one might concate-nate two feature spaces and convert the dictionary learning problem of coupled feature spaces to the dictionary learn-ing problem of single feature space. However ...
