mlpack_det — density estimation with density estimation trees

Synopsis

mlpack_det [-h] [-v] [-f int] [-m string] [-L int] [-l int] [-M string] [-T string] [-E string] [-t string] [-e string] [-V] [-i string]

Description

This program performs a number of functions related to Density Estimation Trees. The optimal Density Estimation Tree (DET) can be trained on a set of data (specified by --training_file or -t) using cross-validation (with number of folds specified by --folds). This trained density estimation tree may then be saved to a model file with the --output_model_file (-M) option.

The variable importances of each dimension may be saved with the --vi_file (-i) option, and the density estimates on each training point may be saved to the file specified with the --training_set_estimates_file (-e) option.

This program also can provide density estimates for a set of test points, specified in the --test_file (-T) file. The density estimation tree used for this task will be the tree that was trained on the given training points, or a tree stored in the file given with the --input_model_file (-m) parameter. The density estimates for the test points may be saved into the file specified with the --test_set_estimates_file (-E) option.

Options

--folds (-f) [int]
The number of folds of cross-validation to perform for the estimation (0 is LOOCV) Default value 10.

--test_file (-T) [string]
A set of test points to estimate the density of. Default value ''. --test_set_estimates_file (-E) [string] The file in which to output the estimates on the test set from the final optimally pruned tree. Default value ''. --training_file (-t) [string] The data set on which to build a density estimation tree. Default value ''. --training_set_estimates_file (-e) [string] The file in which to output the density estimates on the training set from the final optimally pruned tree. Default value ''.
