• Fast EM Clustering
  Rapid Learning of Gaussian Mixture Models from large datasets.
• Simple kd-Trees
  This program constructs a kd-tree from the contents of an input dataset of k-dimensional vectors, and then performs nearest neighbor searches within the kd-tree using query points from a query dataset.
• Dense K Nearest Neighbor
  This program performs fast dense K Nearest Neighbor classification.
• XGDA Learn
  The XGDA Learn software takes link information as input, and learns groups, subgroups and friends (i.e., most likely collaborators) from that link information.
• Fast Classifiers
  A collection of fast classifiers including knn, aknn, naive bayes, decision tree, and logistic regression.
• TCWI (T-Cube Web Interface)
  Front end for interactive visualization, navigation, and analysis of multidimensional time series data
