Restricted Boltzmann Machine (RBM) is a two layer undirected graph model that capable to represent complex distributions. Recent research has shown RBM-based approach has comparable performance with, even performs better than previous models on many collaborative filtering (CF) tasks. However, the intractable inference makes the training of RBM sophisticated, which prevents it from practical ap...

This paper describes a series of experiments conducted within the context of a course on organisational theory which is taught at the Department of Management Sciences at the University of Twente. In 1997 a group-based learning approach was adopted but after the first year it was apparent that acquisition and application of theory by student groups was inadequate. In an attempt to remedy this p...

In this article, we are interested in the tasks collaborative resolution in elearning context, and in the use of information technology to support this activity. A part of this article is devoted to the modeling of the activity of tasks collaborative resolution. Then, we suggest an approach for the automatic perception of the good quality of the users’ contribution. This approach is mainly base...

Online collaborative learning environments are becoming increasingly popular in higher education. E-tutors need to supervise, guide students and look out for conflicts within the online environment ensure a successful experience. Web-based platforms allow interactive elements such as conversational agents disencumber e-tutor. Repeatable tasks, which do not require human response, can be automat...

Collaborative skills have been perceived as the most important by learners, instructors, and employers alike in comparison to communication entrepreneurial skills. Despite its significant role workplace, many find that working together with others may complicate tasks due limited background knowledge problems social dynamics. There has not a single assessment created assess online collaboration...

The increasing involvement of industry in academic research raised concerns whether university-industry projects actually meet the same academic standards as university projects in-house. Looking at the academic output and impact of collaborative versus non-collaborative Ph.D. projects at Eindhoven University of Technology, we observe – unexpectedly – that doctoral candidates who conducted a co...
