A new nature inspired modularity function adapted for unsupervised learning involving spatially embedded networks: A comparative analysis

no code implementations18 Jul 2020 Raj Kishore, Zohar Nussinov, Kisor Kumar Sahu

Unsupervised machine learning methods can be of great help in many traditional engineering disciplines, where huge amount of labeled data is not readily available or is extremely difficult or costly to generate.

Unsupervised Community Detection with a Potts Model Hamiltonian, an Efficient Algorithmic Solution, and Applications in Digital Pathology

no code implementations5 Feb 2020 Brendon Lutnick, Wen Dong, Zohar Nussinov, Pinaki Sarder

We propose a fast statistical down-sampling of input image pixels based on the respective color features, and a new iterative method to minimize the Potts model energy considering pixel to segment relationship.

Clustering Community Detection +3

An interacting replica approach applied to the traveling salesman problem

no code implementations27 Jun 2014 Bo Sun, Blake Leonard, Peter Ronhovde, Zohar Nussinov

The {\it ensemble} of replicas evolves as to maximize the inter-replica correlation while simultaneously minimize the local intra-replica cost function (e. g., the total path length in the Traveling Salesman Problem within each replica).
