Multi-Task Preference Learning with Gaussian Processes
Speaker
Abstract
| Preference learning is concerned with the acquisition of preference models from data – it involves learning from observations that reveal information about the preferences of an individual or a class of individuals, and building models that generalize beyond such training data. In many cases, data for a single individual is scarce, and it pays to build a hierarchical model of preferences, where models for individuals share a common prior. This setting is referred to as multi-task learning. In particular, we here consider the application of multi-task Gaussian processes to the learning of preferences, where each of the models for individual subjects is a nonparametric Gaussian process. We demonstrate the usefulness of our approach on an audiological data set. |
