category_encoders
A library of sklearn compatible categorical variable encoders
clustering-ensemble
Removal of information from co-association matrix for clustering ensemble
ClusteringDirectionCentrality
A novel Clustering algorithm by measuring Direction Centrality (CDC) locally. It adopts a density-independent metric based on the distribution of K-nearest neighbors (KNNs) to distinguish between internal and boundary points. The boundary points generate enclosed cages to bind the connections of internal points.
Deep-Semi-NMF
Theano-based implementation of Deep Semi-NMF.
EBDM
Implemented the research paper ‘A Unified Entropy-Based Distance Metric for Ordinal-and-Nominal-Attribute Data Clustering’ by Zhang et al. and built a python package for finding a common distance matrix for the ordinal and nominal data from any kind of questionnaire data, based on entropy measures. Tested the package on multiple datasets for robustness.
gramm
Gramm is a complete data visualization toolbox for Matlab. It provides an easy to use and high-level interface to produce publication-quality plots of complex data with varied statistical visualizations. Gramm is inspired by R's ggplot2 library.
higher-order-organization-matlab
Experimental Matlab code for methods and some examples in "Higher-order organization of complex networks"
TestCat
Clusterability test for categorical data: A testing-based approach to assess the clusterability of categorical data (2023)
