TRPL+K: Thick-Restart Preconditioned Lanczos+K Method for Large Symmetric Eigenvalue Problems
Lingfei Wu, Fei Xue, Andreas Stathopoulos
The Lanczos method is one of the standard approaches for computing a few eigenpairs of a large, sparse, symmetric matrix. It is typically used with restarting to avoid unbounded gr…
Revisiting Spectral Graph Clustering with Generative Community Models
Pin-Yu Chen, Lingfei Wu
The methodology of community detection can be divided into two principles: imposing a network model on a given graph, or optimizing a designed objective function. The former provid…
Large Teams Have Developed Science and Technology; Small Teams Have Disrupted It
Lingfei Wu, Dashun Wang, James A. Evans
Teams dominate the production of high-impact science and technology. Analyzing teamwork from more than 50 million papers, patents, and software products, 1954-2014, we demonstrate…
Similarity Preserving Representation Learning for Time Series Clustering
Qi Lei, Jinfeng Yi, Roman Vaculin +2
A considerable amount of clustering algorithms take instance-feature matrices as their inputs. As such, they cannot directly analyze time series data due to its temporal nature, us…
