Neuroscience achieving insight from code-breaking

The Enigma machine and de Bruijn sequences inform neuroscience analyses, including quotes from Josh Gold and Geoff Aguirre.

The Penn scientists have taken their cues from a 73-year-old algorithm that British code-breaker Alan Turing used to read secret German messages during World War II, and a mathematical sequence more famously used to break into digital keypad locks on cars.

Machine Learning: Exceeding Chance Level By Chance

Possible warnings for machine learning studies? "Chance" classification depends on the number of samples - if samples are not infinite, it may be higher than expected.

UPDATE: The general consensus seems to be that permutation testing, as commonly done, is valid and avoids the potential problems laid out by the authors.
