Goal of the course | Data science deals with the huge flow of data generated in variety of disciplines and ranging from the internet, to biology to physics and astronomy. For instance, high energy physics experiments as well as astronomical observations can generate multiple terabytes of data per day and the analysis of these “big data” sets requires novel, efficient methods. Data science is an interdisciplinary field that unifies statistics, data analysis, machine learning and other related methods, in process of analyzing and understanding actual phenomena from data. Machine learning (ML) methods have recently played a very important role in making advances in data science. Deep Learning (DL), which is a sub-field of ML, has played a phenomenal role in making advances in many fields such as computer vision, speech recognition, machine translation, and robotics amongst other fields. In physics, ML and DL can detect and classify astronomical objects, track particles in detector arrays, and predict the state of complex, nonlinear dynamical systems. |
