abstract background and purpose: aging is associated with brain changes and reduction in motor skill acquisi­tion that can limit its functional capacity. one of the effective interventions is using transcranial direct current stimulation (tdcs). the aim of this systematic review was to assess the effect of tdcs on learning and motor skill in healthy older adults. materials and methods: a litera...

Ensemble methods such as boosting combine multiple learners to obtain better prediction than could be obtained from any individual learner. Here we propose a principled framework for directly constructing ensemble learning methods from kernel methods. Unlike previous studies showing the equivalence between boosting and support vector machines (SVMs), which needs a translation procedure, we show...

Local minima represent a major problem for neural network learning procedures. In this article we present a new procedure, collective learning, that leads to improved global convergence. We have tested our procedure on several neural networks and on the multimodal functions proposed by De Jong and Rastrigin. In our tests we have reached a success ratio of 100 %. In addition we give a few remark...

We present Z-DOC, a (prototype) serious game for training plastic surgery residents the steps comprising the Z-plasty surgical procedure. Z-DOC employs touch-based interactions and promotes competition amongst multiple players/users thus promote engagement and motivation. It is hypothesized that by learning the Z-plasty procedure in an interactive, engaging, and fun gaming environment, trainees...
