R&D Backlog

December 30, 2019

The purpose of my blog is to post unpolished, throwaway, R&D type stuff. The more in-depth discussions will generally be posted on Medium.com and the posts here will contain more interactive demos. Below is a growing list of things I’m curious to try out and research more, as well as new ideas I come across.

To do

  • Arxiv.org scraper
    • Following Jeff Dean’s advice to read lots of paper abstract, I wrote a trivial API that queries arxiv.org and returns a list of abstracts for quick scanning. Now I need to post that code.
  • Genetic algorithms (done)
    • I’m currently mostly curious about neuroevolution in general.

Genetic Algorithm Example

In this toy demonstration of genetic algorithms, the algorithm learns some arbitrary 2D function. The “chromosome” is represented by a sequence of <distance, angle> pairs. By rendering the first point at some location, we can render the next point in the sequence by computing the <x, y> coordinates relative to that first point by using the distance and angle for the current gene.
