WebNov 30, 2024 · To address this problem, we propose an unsupervised domain adaptive dictionary learning (UDADL) model to bridge source domain and target domain by learning a shared dictionary. The encoding of the two domains on this dictionary are constrained to be mutually embedded on each other. WebWith the deep application of artificial intelligence and big data in education, adaptive learning has become a new research hotspot in online education. Based on the systematic review of the connotation and research progress of adaptive learning, a new definition of adaptive learning is given.

WebApr 12, 2024 · In this work, we propose a novel domain-adaptive dictionary learning framework for cross-domain visual recognition. Our method generates a set of intermediate domains. These intermediate domains form a smooth path and bridge the gap between the source and target domains. Web2.2 Unsupervised Domain Adaptive Dictionary Learning (UDADL) Similar with conventional dictionary learning, the UDADL model aims to learn a dictionary D based on the source and target samples X and the optimal D can be obtained by solving the following optimization problem: {D∗,A∗} = argmin D,A X−DA 2 F = arg min D,As,At [X s,X t]−D[A,A ...
WebFeb 17, 2024 · Multi-Kernel Coupled Projections for Domain Adaptive Dictionary Learning Abstract: Dictionary learning has produced state-of-the-art results in various classification tasks. However, if the training data have a different distribution than the testing data, the learned sparse representation might not be optimal.
