Phoenix Tool: A Support to Semantic Learning Model
Share and reuse of learning objects are an important issue, that are not solved by simply adding a metadata description. Their contextualisation as well as their level of granular...

Weakly Supervised Learning of Foreground-Background Segmentation using Masked RBMs
Abstract. We propose an extension of the Restricted Boltzmann Machine (RBM) that allows the joint shape and appearance of foreground objects in cluttered images to be modeled indep...

Restricted Boltzmann machines for collaborative filtering
Most of the existing approaches to collaborative filtering cannot handle very large data sets. In this paper we show how a class of two-layer undirected graphical models, called R...

Modeling of Process-Oriented Learning Designs
Process-oriented learning designs (POLD) are used to describe innovative teaching activities (processes) that can be generalised and used across different disciplines. This paper ...
