Ask an MLer: Classification and Hypothesis Testing Often scientists want to use machine learning as an analytical tool to answer a question about a data set. However, transitioning from classification accuracy to a hypothesis test can be tricky. Today we answer a question from a neuroscientist on the subject. How can I tell if my...

Organizing Research Papers with Mendeley and Dropbox

As academics we spend a lot of time reading, and a lot of time procrastinating.  At one point, my favorite procrastination activity was obsessively researching the “best” way to organize research papers for reading (instead of, you know, reading them).  I’ve had many systems; some paper based, and now mostly electronic.  I’ve finally settled on...

How a Machine Learner Should Approach a Neuroscientist

Image from Mitchell, Tom M., et al. “Predicting human brain activity associated with the meanings of nouns.” science 320.5880 (2008): 1191-1195. Machine learners are always on the prowl for new datasets to analyze. Neuroscientists are forever searching for new techniques to help make the most of their data. Naturally, there’s been an explosion of collaborations between...
