Predicting Which Hiragana Character You’re Drawing
I tried to take a shot @ the problem shown above. Turns out just high-school level math is sufficient to make a decent classifier for this. In the Japanese alphabet(s), a character is composed of strokes. These strokes have a fixed order. This restriction is pretty much all you need. I grab the stroke’s end [...]

Awesome Problem
I had the opportunity to work on an interesting problem: Find a decent approximation for the Zeta function (large values), given by: So, to make any sort of headway, I decided that I would have to look at the graph. Hence, I whipped up a script in Python: #!/usr/bin/env python #Author: Shriphani Palakodety [...]
