WebIn semi-supervised label propagation (LP), the data manifold is approximated by a graph, which is considered as a similarity metric. Graph estimation is a crucial task, as it affects the further processes applied on the graph (e.g., LP, classification). As our knowledge of data is limited, a single approximation cannot easily find the appropriate graph, so in line …

WebIn addition, the traditional method of constructing similarity graphs is based on the pairwise distance, so it is extremely sensitive to the original data, and also lacks specific physical meaning from the perspective of probabilistic prediction. Final, the traditional metrics based on Euclidean distance is difficult to tackle non-Gaussian noise.
