Douglas can help you figure out what you need to know specifically for machine learning in regards to your mathematics background. He will be key to my next 7 months of training in a machine learning course, by providing tutoring when needed and making sure my efforts are focused in the math subjects that are most relevant to machine learning.
I could tell how much he cares about a students learning experience, and creating a comfortable environment that makes it valuable for the learner - I never felt talked down to during our lesson nor did he ever have an impatient tone... All in all, I walked away from our lesson with more understanding of the R programming language, how to work in the R Studio IDE, and more knowledgeable about some of the key points in Machine Learning with R. I would highly recommend a lesson with Brad.
Peter taught me machine learning. Peter explains things very well. He simplifies things by breaking problems into sub problems and patiently going over each of them. This was the first session in machine learning and it was a great intro to machine learning.
