Structuring Machine Learning Projects

Andrew Ng did a pretty good talk on machine learning project management based on his experience as a director:

If you've never had a course I suggest you try some that focus on concepts like overfitting /underfitting and their relationship with the data you feed your model and the hyperparams you choose.

As a reference, take a look at this book:
