This course introduces students to the concept of a knowledge based cognitive computing system, as made possible by recent advances in artificial intelligence. Students will work with IBM Watson, a cognitive A.I. with the capability of machine learning and sensory processing. Cognitive A.I. expert and associate director of UX at IBM, Han-Shen Chen will be leading out the experiment and the implementation of Watson for this course. Over the semester, students will explore live cognitive data, experiment with applications of deep learning, deconstruct natural language processing in the context of art and design, learn to articulate their concept into a data analytic mechanism within the cognitive framework, and eventually emerge them into cognitive UX/UI - a dynamic, live, interconnected, and interactive UX/UI design approach to future computing systems. Finally, students will be expected to develop radical and cognitive UX/UI projects with existing Watson services. This course welcome students who have basic knowledge in code, interaction design, and are interested in exploring the topics involved.
