About the Course

In this 2 hour guided project you will learn how to deal with imbalance classification problems in a profound manner, applying several resampling strategies and visualizing the effects of resampling on imbalance classification dataset. Note: This project works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions....

Learnt lot of new technique for handling imbalanced dataset. Good project. However, I strongly recommend downloading the dataset from internet and run locally. Coursera's platform for running the project is confusing.....Overall good project.

Pro: Covers various techniques for handling imbalanced data sets. With metrics and visualizations

Con:

- Audio is sometimes hard to hear. However the closed captions help. - The Rhyme platform is problematic. Eventually I downloaded the dataset and ran the notebook locally. - The complete notebook isn't available. I think it is better when you have a complete notebook and can concentrate on listening to the lecturer and annotating the notebook.

Other: - There is no theory, just a demonstration of various techniques for under and over sampling. On the whole I think this is positive. There are a lot of techniques. So first find the one that is relevant to your data-set - and then study it further on the Internet. - It seems that there have been changes in the imblearn library so sm = SMOTE(), x_sm, y_sm = sm.fit_sample(X,Y) doesn't work. You need to change it to fit_resample().

Conclusion: Would definitely take another project given by the lecturer. Mainly because of the emphasis on visualizations and metrics. With so many examples on the internet - you'll always eventually have an ML that runs. The real challenge is ensuring the results are fit for use.
