The idea starts with implementing capturing of user interactions with the system, thereby recording all their interactions such as entering data into a web form. Further, this data can be pivoted to build views and subsequently other tables that aid in building predictions for any form element considering all past inputs in that session. Predictions are built using a machine learning method Naive Bayesian Inference. This talk discusses challenges and issues and favorable outcomes in implementing a succesful predictions building system, while the user is still interacting with the system.

P(H|E) – probability of hypothesis given the evidence is computed on the fly where P(E|H) – probability of evidence given the hypothesis (possible values of the output variable) is first computed. The analysis is dynamic and additive in a way that if more fields are entered by the user on the web form, all of them are considered as evidence to determine the probability of a value in the next (unaltered) field.
