Keep ‘Em Flying Laser Peening Keeps Aircraft Turbine Blades in Action

How many times in the past year have I heard the word " syn-ergy " ? And of those times, how many were at home with my wife or out at a restaurant? I would guess that the ratio is something like 10:0, because like so many other management clichés or buzzwords, " synergy " lives only at the office. Things like " cooperation, " " give-and-take, " and " understanding " live at home. Why does this ...

"Keep Your Eyes on 'em all!": A Mobile Eye-Tracking Analysis of Teachers' Sensitivity to Students

This study aims at investigating which cues teachers detect and process from their students during instruction. This information capturing process depends on teachers’ sensitivity, or awareness, to students’ needs, which has been recognized as crucial for classroom management. We recorded the gaze behaviors of two pre-service teachers and two experienced teachers during a whole math lesson in p...

A Probabilistic Analysis of EM for Mixtures of Separated, Spherical Gaussians

We show that, given data from a mixture of k well-separated spherical Gaussians in Rd , a simple two-round variant of EM will, with high probability, learn the parameters of the Gaussians to nearoptimal precision, if the dimension is high (d lnk). We relate this to previous theoretical and empirical work on the EM algorithm.
