Overall this is a very practical course. One complain is that for the programming assignment, the python version in the Jupyter notebook is not the latest one. That would cause a waste of time in debugging since it does not support some codes and you could not figure out the cause of the failure from the auto grading.
This course covers the core techniques used in data mining, including frequent pattern analysis, classification, clustering, outlier analysis, as well as mining complex data and research frontiers in the data mining field.
