GANs Are Hot- So What Is A GAN?

By Dr. Tim Oates, Chief Data Scientist Generative Adversarial Networks, or GANs, are one of the most exciting ideas in machine learning right now.  Yann LeCunn, perhaps best known for inventing Convolutional Neural Networks, said in a 2016 interview: The most important [new idea in machine learning], in my opinion, is adversarial training (also called…

How is Learning Even Possible?

By Jitendra Subramanyam We’re surrounded by the successes of machine learning. Self driving cars, sophisticated translation, being able to tell Alexa what music we want…. These sucessses are real, yet for most of us (myself included), they seem magical. As the science fiction writer Arthur Clarke wrote in 1973, “Any sufficiently advanced technology is indistinguishable…

Exploration vs. Exploitation

By Dr. Tim Oates, Chief Data Scientist There’s a branch of machine learning called reinforcement learning (RL) that deals with making decisions under uncertainty.  It works a little like people do when learning to play a new video game.  You look at the screen, assess the situation, try a few things, see what works and…

The Value of Going “Old School” in Data Science

By Dr. Tim Oates, Chief Data Scientist When I entered graduate school to work on a Ph.D. in Artificial Intelligence, the outlook for the field was uncertain, with dwindling attendance at the main national conferences and at best a lukewarm job market.  Things could not be more different today!  There’s genuine excitement in academia and…
