Title: $L^{\gamma}$ Semi-Supervised Learning for Classification

Abstract: Graph-based semi-supervised learning are methods for classification that combine expert knowledge from (generally few) labelled samples with the structural organization (natural or inferred) of large datasets. PageRank is one famous algorithm that undergoes a standard random walk interpretation to explain how the a priori information diffuses over the entire graph. After extending PageRank to long-range diffusion processes, such as Levy flights, we will show how powers of the combinatorial Laplacian can improve classification performances in critical situations where standard SSL methods are known to behave poorly. Then, we will show that $L^{\gamma}$-SSL yields a pertinent proxy for the NP-hard problem of unsupervised normalized cut.
