1. A computer-implemented system that facilitates model enhancement, comprising: at least one processor configured to provide a modeling component that builds and runs a model based on data associated with a user, the model indicating interruptability of the user; and a sampling component that determines a time at which to obtain additional data associated with the user for building the model, the data being obtained by probing the user, and the time being determined based on: failure analysis of the model; and a state of the user.

The system of claim 1 , wherein the sampling component initiates sampling of a new set of data when the model performs below a predetermined criterion.
