The Electrical Engineering department at Caltech has a faculty opening, and is targeting machine learning as a key area of interest. Reviewing of applications has just begun (started December 15), but all applications received by January 15th will be reviewed.
Caltech is an extremely small school (~300 faculty total), and departmental boundaries are almost meaningless. I anticipate having many connections to the Electrical Engineering department, so any machine learning person who joins will definitely not feel alone. So please apply if you're interested!
