Extreme Learning Machine Toolbox

This is a toolbox to enable the creation of extreme learning machines in MATLAB. It is possible to create a desired model using just a few lines of code. This version also includes the possibility to add functional link between the inputs and output.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

You just need MATLAB. This toolbox has been developed on MATLAB R2019a, but should also be compatible with earlier versions.

Installing

Toolbox installation in MATLAB is rather simple. You just need to add a copy of the source codes (src directory) in the MATLAB paths.

This can be made programatically with the following code:

addpath('<directory>/ELM')

Two simple demos can be found in the examples directory. To run them, you just need to execute the scripts Demo_classification.m and Demo_regression.m.

Versioning

We use a three-codes versioning system: vA.B.C.

• A stands for the major revision, and will be used when a major new feature is added or compatibility to previous major revision is lost.
• B stands for minor revision, where new features will be added.
• C is used for minor adjustments and bug fixing.
