One day, while I was walking around Cambridge, I had a random thought – how do the characters on the Simpsons feel about each other? It doesn’t take long to figure out how Homer feels about Flanders (hint: he doesn’t always like him), or how Burns feels about everyone, but how does Marge feel about Bart? How does Flanders feel about Homer? I then realized that I work with algorithms – maybe I would be able to devise one to answer this question. After all, I did something similar with the Wikileaks cables.

Linear regression is a very basic technique that we use a lot in machine learning. In a lot of cases (and I have been guilty of this), we just use it without much thought as to how the internals actually work.

I had my natural predilection towards math crushed out of me at some point in school, and after that point, Math (yes, we are referring to the higher power of math) and I had a wary understanding. I dabbled quietly, and Math turned a blind eye to me ignoring some of its deeper theory. When I stuggled loudly, Math did its best to hide its smirks. I generally refrained from throwing textbooks.
