On the Borders of Statistics and Computer Science

Machine learning in computer science and prediction and classification in statistics are essentially equivalent fields. I will try to illustrate the relation between theory and practice in this huge area by a few examples and results. In particular I will try to address an apparent puzzle: Worst case analyses, using empirical process theory, seem to suggest that even for moderate data dimension and reasonable sample sizes good prediction (supervised learning) should be very difficult.

Thermodynamic Equilibrium

This applet is designed to simulate the diffusion process which occurs when gases of different temperatures are mixed. To activate the mixing, click one time on the red vertical bar that separates the two chambers. After a few moments, the bar will turn green and the gases will start to mix and share their energy. The counters in the respective chambers indicate the number of particles in that chamber. The thermometers will start to change temperature as the mixing process is occurring. Eventually both chambers will reach the same temperature.
