we’ll be looking at different ways to do similar things • Feel free to raise questions, make comments, criticize, etc. as we go along! 14What this is about? • Important note: throughout this talk we’ll be looking at different ways to do similar things • Feel free to raise questions, make comments, criticize, etc. as we go along! 15 There will be lots of code in these slides, so pay attention

this library was to make it simple and short. When clobbered into a single file by removing all the comments, micrograd++ comes out to be < 500 lines. When compiled with the highest optimization -O3, the static
