This is using GA to find the optimal set of inputs to utilize.<br /><br />In the context of my commentary, however, a true GA allows you to optimize to almost any goal (called fitness function) that you want. Whereas the tree based classifier only optimizes at finding the best set of rules to separate classes (typically based on probabilities or information theory measures).<br /><br />I plan on putting a tutorial up on this in the future.Intelligent Tradinghttps://www.blogger.com/profile/17765336450326139518noreply@blogger.comtag:blogger.com,1999:blog-107568321062020427.post-41489001388150101662010-02-13T13:41:56.441-08:002010-02-13T13:41:56.441-08:00When you say optimize with Genetic Algorithms are ...When you say optimize with Genetic Algorithms are you referring to allowing the GA to weed out certain inputs before using the chosen algorithm to build a model?<br /><br />Thanksbozwoodnoreply@blogger.com
