Together Duke is pleased to announce the Natural Language Processing Winter School (NLP-WS), being offered in January 2020, as a three-day class that provides lectures on the fundamentals of machine learning, and natural language processing. Machine learning is a field characterized by development of algorithms that are implemented in software and run on a machine (e.g., computer, mobile device, etc.). Each such algorithm is characterized by a set of parameters, and particular parameter settings yield associated algorithm characteristics. The algorithms have the capacity to learn, based on observed data. By "learn" it is meant that the algorithm can rigorously quantify which parameter settings are best matched to the data of interest.
