A key objective of SWITCH is to support Learning Alliances (LAs) in the development of integrated urban water management strategies. Theme 2 of the SWITCH project is focused around sustainable stormwater management and its interactions with other sectors of the urban water cycle (e.g. water supply, eco-sanitation and urban agriculture) with a particular emphasis on achieving a paradigm shift wh...

In this paper we present a generative latent variable model for rating-based collaborative filtering called the User Rating Profile model (URP). The generative process which underlies URP is designed to produce complete user rating profiles, an assignment of one rating to each item for each user. Our model represents each user as a mixture of user attitudes, and the mixing proportions are distr...

Unsupervised dependency parsing aims to learn a dependency parser from unannotated sentences. Existing work focuses on either learning generative models using the expectation-maximization algorithm and its variants, or learning discriminative models using the discriminative clustering algorithm. In this paper, we propose a new learning strategy that learns a generative model and a discriminativ...
