Introductory Master's Course to Artificial Intelligence (AI), taught by award-winning experts of the Swiss AI Lab IDSIA, and USI. The focus is on Machine Learning (ML). According to Computer World (2009), expertise in ML is the top skill sought by IT employers. Today ML is everywhere: search engines use it to improve answers to queries, email programs use it to filter spam, banks use it to predict exchange rates and stock markets, doctors use it to recognize tumors, robots use it to localize themselves and obstacles, video games use it to enhance the player's experience, smartphones use it to recognize objects / faces / gestures / voices / music, etc. After the first few lectures of the basic AI course on ML, AI master students will already know how to train self-learning artificial neural networks to recognize images and handwriting better than any other known method. They will rapidly gain familiarity with state-of-the-art algorithms developed at IDSIA and other AI labs.
