- Parallel Distributed Processing of Weka Algorithms in Matlab
- License: Shareware
- Price:


The code given shows how Weka algorithms can be run in parallel across distributed computers using Matlab to take advantage of available hardware and quicken algorithm completion time on multiple data sets or parameter sets. Parallel processing of Weka algorithms is handled here in Matlab as support for parallel processing in Weka does not seem to be fully fledged as yet. A timeout can be specified on algorithm/job processing time. This is useful if algorithms can be potentially long-running or non-terminating, or when there are a large number of experiments to ensure they finish within a reasonable amount of time. Before the provided code can be executed: * Define a parallel configuration in Matlab. See "Configuring Parallel Processing.txt". * Assign the configuration name to variable "config" in runParallelWeka.m. * Copy the Weka...

- Shaded Correlation Table
- License: Shareware
- Price:


ShadedCorrelationTable produces a correlation table for a set of variables, enhanced graphically with shading according to correlation values. Upper or lower ranges of correlation values may be highlighted through the interface controls. Two methods are provided to do this: a decay function that softens shading of values of less interest, or, shading according to a discrete threshold. Pearson's linear correlation coefficient is used. Usage: ShadedCorrelationTable(x, xLabels); Example: load('demo data.mat'); ShadedCorrelationTable(data.x,data.labels);

- XY 3D Density Plot (for two-class data)
- License: Shareware
- Price:


XY3DDensityPlotView is used to visualize the density of points described by two variables X and Y, as a surface plot. This may be useful when points are densely packed and overlapping, as in this case a scatterplot may be limited in revealing their actual distribution. The XY data must be labelled, each data point belonging to one of two classes (e.g. positive and negative). A surface is produced on the density of points in each class, and the two surfaces are shown together on the same axes. Interface controls are provided to interactively refine smoothing parameters. Two smoothing methods are provided, Eiler and Filter, which give a slightly different effect in terms of the surface produced. Usage: XY3DDensityPlotView(x, y, removeOutliers, xLabels) Example: This example uses the demo data provided in the source files....
