Hi friends
Just published the last part of a 3 part article about predicting malignancy in tumors combining a 2 layer neural network built from scratch in Python and the Wisconsin dataset. Although this is all written in standard Python, I was inspired to begin writing articles because of fast.ai and I mention fast.ai related stuff at different points in the articles. I recently finished watching the first pass of the new 7 lessons of V3 and I look forward to continue enjoying fast.ai 
The articles include 3D animations of loss landscapes that I created specifically for them
