We introduce the collaborative multi-output Gaussian process (GP) model for learning dependent tasks with very large datasets. The model fosters task correlations by mixing sparse processes and sharing multiple sets of inducing points. This facilitates the application of variational inference and the derivation of an evidence lower bound that decomposes across inputs and outputs. We learn all t...

computer-supported collaborative learning (cscl) is a new trend in educational sciences. this study investigates how knowledge sharing and transferring can be facilitated by using cscl in a problem-solving setting. intervention of research is education regarding sustainable water resources management (swrm) by computer-supported collaborative learning (cscl). the purpose of this research was to...

A sizeable body of research into instructed pragmatics roots from the noticing hypothesis: comparing im- plicit and explicit instruction. It is only recently that other theories, including the output hypothesis, have been researched as possible explanations of interlanguage pragmatic development. Pursuing the same line of research, the present study addressed the impact of collaborative o...

We study university projects and research collaboration projects with industry that are supported by government grants. First, we propose a theoretical model to analyze optimal decisions in these ventures. Second, we test our theoretical results with a unique dataset containing academic publications and collaborative research funds for all the academics at the major engineering departments in t...

Two experiments examined collaborative memory for information that was studied by all group members (shared items) and information that was studied by only a subset of group members (unshared items). In both experiments significant collaborative inhibition (reduced output of the collaborative groups relative to the pooled output of individuals) was obtained for both shared and unshared informat...

One of the distinguishing features of implementation research is the importance given to involve implementers in all aspects of research, and as users of research. We report on a recent implementation research effort in India, in which researchers worked together with program implementers from one of the longest serving government funded insurance schemes in India, the Rajiv Aarogyasri Scheme (...
