13th October 1972: A Uruguayan Air Force plane, commissioned for a civilian flight, crashes in the Andes. Among the forty passengers are a first-division rugby team, accompanied by family and friends. Hindered by treacherous conditions, the search and rescue efforts cannot locate the wreckage, and are abandoned after eight days. Ten weeks later, two unkempt boys are spotted by a muleteer high in the Chilean foothills. One throws a note to him, across a mountain torrent: I come from a plane that fell in the mountains... In the plane there are still fourteen injured people... Drawing on extensive original research, the author sheds new light on this extraordinary story from a perspective of fi...

Learning to rank refers to machine learning techniques for training a model in a ranking task. Learning to rank is useful for many applications in information retrieval, natural language processing, and data mining. Intensive studies have been conducted on its problems recently, and significant progress has been made. This lecture gives an introduction to the area including the fundamental problems, major approaches, theories, applications, and future work. The author begins by showing that various ranking problems in information retrieval and natural language processing can be formalized as two basic ranking tasks, namely ranking creation (or simply ranking) and ranking aggregation. In rank...
In machine learning applications, practitioners must take into account the cost associated with the algorithm. These costs include: Cost of acquiring training dataCost of data annotation/labeling and cleaningComputational cost for model fitting, validation, and testingCost of collecting features/attributes for test dataCost of user feedback collect
