We present algorithms for constructing nearly-optimal hierarchical clustering trees with respect to Dasgupta`s cost function on well-clustered graphs.

We introduce a neural network pruning algorithm using spectral graph sparsification, empirically demonstrating its effectiveness in preserving performance at higher sparsity levels and providing theoretical analyses of local and global network connectivity.

We develop simple theory and use experiments to show that the episodic training setup for Matching Networks and Prototypical Networks is inefficient.

We show that a path-like cluster structure can be found in directed graphs, by performing spectral clustering on the first eigenvector of a newly defined Hermitian adjacency matrix.

As one of the first to do this in the world, we use drones equipped with infrared and RGB cameras to map geothermal surface manifestations

Using theory from sociology, we develop bodily cues in virtual agents which effectively communicate social engagement.
