Title: Combining tree-based and dynamical systems for the inference of gene regulatory networks
We propose a new hybrid approach for reconstructing the topology of gene regulatory networks (GRNs), called Jump3, exploiting time series of expression data. Jump3 is based on a formal on/off model of gene expression, and uses a non-parametric procedure based on decision trees (called “jump trees”) to reconstruct the GRN topology, allowing the inference of networks of hundreds of genes. We evaluated the performance of Jump3 on in silico and synthetic networks, and applied the approach to identify regulatory interactions activated in the presence of interferon gamma.

Title:  Visual attention of an audience during a lecture
I will report a novel application of a fixation-tracking procedure to the whole of an audience, in this case the @250 students
in a Psychology 1 lecture. Where do students look during a lecture? Where do they sit, for that matter? Do students with different personalities watch and attend differently? These data are from a dissertation project in Psychology, carried out by Cara Wase.
This is an experiment using “mass eye-tracking”  of a kind. I will introduce some of the basic concepts of eye-movements and visual attention, show some heat-maps, and ask do we take anything from this kind of research to improve our presentations?
