In this work, we present a dimensionality reduction algorithm, aka. sketching, for categorical datasets. Our proposed sketching algorithm Cabin constructs low-dimensional binary sketches from high-dimensional vectors, and our distance estimation Cham computes close approximation of the Hamming between any two original vectors only their sketches. The minimum dimension required by to ensure good...
The graphical displays shown here are implemented in SAS/IML software whose combination of matrix operations, built-in Statistical methods for categorical data, such as loglinear models functions for contingency table analysis, and graphics provide a and logistic regression, represent discrete analogs of the analysis of convenient environment for graphical display for multiway variance and regr...
data aims at considering numeric data, categorical data or a mixture of both. For such data, the concentration was finding a relationship between the data points to be clustered. The relationships were limited to being either binary or fuzzy. Both involved a numeric value called distance or any other similarity measure between two data points and cluster them together if found similar. With tim...
The three-parameter cluster model is a combinatorial stochastic process that generates categorical response sequences by randomly perturbing a fixed clustering parameter. This clear relationship between the observed data and the underlying clustering is particularly attractive in cluster analysis, in which supervised learning is a common goal and missing data is a familiar issue. The model is w...
