There are NEW livestream videos about RapidMiner! Visit my Channel here
In this Rapidminer Video Tutorial I show the user how to use the Parameter Optimization operator to optimize your trained data. The example shows how Rapidminer iterates the learning rate and momentum for a Neural Net Operator to increase the performance of the trained data set.
Video #14 will be about web mining financial text data.
Updated: this tutorial is still valid for RapidMiner versions 5+, 6+, and 7+
