This weekend, Facebook is opening its Menlo Park campus to teams Coding for Cuba.

The challenge: “Build hardware or software tools that can be used by people in Cuba for connectivity and access to information, entrepreneurial support, or journalism and digital advocacy.”

The two-day hackathon, to be held April 25 and 26th, will end in a competition for $7000 in prizes, judged by a panel that includes folks from Facebook, Yahoo, Salesforce, and Stanford. It’s not too late to sign up here. You can also follow the ideas that develop here.

And I’ll fill you in on the winning projects when they are announced.

Think of the many tasks to which computers are being applied that in the not-so-distant past required human intuition. Computers routinely identify objects in images, transcribe speech, translate between languages, diagnose medical conditions, play complex games, and drive cars.

The technique that has empowered these stunning developments is called deep learning, a term that refers to mathematical models known as artificial neural networks. Deep learning is a subfield of machine learning, a branch of computer science based on fitting complex models to data.
