DR 3.3: Second set of prototypes of user model and action selection algorithms; first evaluation.

This document describes the second set of prototypes of the PAL user modeling algorithms and action selection that have been developed during the third year of the project in PAL's work package 3 (WP3). The overall objective of WP3 is to adapt the behavior of the PAL system to each of its users. This  adaptation is necessary to ensure 1) engagement of the user and 2) increased effectiveness in personal goal achievement. To reach these objectives, the PAL system leverages user models and action selection architectures. The users models are built from the data and the interactions of the users, which provide useful information on their preferences or specicities.
