User-friendly software has been created to allow users to apply several Artificial Neural Network (ANN) model development techniques. The software is an add-in for Microsoft Excel® that implements the main steps in ANN model development, from data pre-processing, through to ANN training and validation; all within the Excel application environment. The software has been developed in C++, so that it combines fast computation with the ease and convenience of pre- and post- analysis of data within an Excel workbook.
