Reconstructing phase space and estimating maximal Lyapunov exponent from experimental time series
Written by Ian Kilgore in math on Sun 26 July 2015. Tags: chaos, geometry, research, experimental data,
In the course of my research I needed to demonstrate that some experimental data is chaotic. This post is an example of how I reconstruct phase space from 1-D experimental data by the method of delays, plot the underlying attractor, and estimate the maximal Lyapunov exponent (characterizing the divergence of the system).
Feature Generation and Selection for Single Character Recognition
Written by Ian Kilgore in machine learning on Sat 11 July 2015. Tags: python, MATLAB, computer math, OCR, feature selection,
I design features for single-character image recognition and implement a variety of feature selection techniques in order to generate a parsimonious model.
Playing Capitals with OpenCV and Python

On Monday evening I had dinner with a friend who showed me the game Capitals and suggested it might be interesting to play it programmatically. tl;dr: I spent the last 18-20 working hours doing that (Github link)

Programmatically-Generated LaTeX Sieve of Eratosthenes
Written by Ian Kilgore in misc on Thu 11 September 2014. Tags: LaTeX, jokes, math,
(tl;dr: see PDF here). For a top-secret joke project I am learning to program in LaTeX as if it were a general-purpose language. LaTeX is my favourite way to write scientific papers, but no one should use it for programmatic logic. Along the way I have implemented a Sieve ...
Inverse-Square Laws: A Physical Consequence of the Geometry of Space
Written by Ian Kilgore in math on Wed 10 September 2014. Tags: physics, geometry, kant, math,
The ubiquitous inverse-square laws in physics are a necessary consequence of the three-dimensional nature of space. Barrow shows that Kant was the first to recognize the geometrical connection, although he got it backwards. I explain the geometrical reason for inverse-square laws and follow Kant's argument. Thanks, Kant. Thant.
