An embodiment of the present invention is directed to a feedback-based system and methodology for dynamic lightweight personalized analytics (DLPA). Disclosed embodiments include a process for dynamically leveraging various inputs such as behavioral and other analytics types, and using a small number of dynamically adjusted parameters, a small memory footprint and optimal computation, to deliver behavioral and other suggestions for customer behavior. In addition, certain actions are cancelled, prior to their completion, based on new, dynamically discovered customer behaviors.
