Compressed Sensing in Python
In this post I’ll be investigating compressed sensing (also known as compressive sensing, compressive sampling, and sparse sampling) in Python. Since the idea of compressed sensing can be applied in wide array of subjects, I’ll be focusing mainly on how to apply it in one and two dimensions to things like sounds and images. Specifically, I will show how to take a highly incomplete data set of sign
Fast Lomb-Scargle Periodograms in Python | Pythonic Perambulations
Edit, Spring 2017: For an in-depth guide to the practical use of Lomb-Scargle periodograms, see the paper discussed in A Practical Guide to the Lomb-Scargle Periodogram. Edit, Summer 2016: All of the implementations discussed below have been added to AstroPy as of Version 1.2, along with logic to choose the optimal implementation automatically. Read more here: astropy.stats.LombScargle. The Lomb-S
Hacking an epic NHL goal celebration with a hue light show and real-time machine learning - François Maillet - Blog
Hacking an epic NHL goal celebration with a hue light show and real-time machine learning See media coverage of this blog post. In Montréal this time of year, the city literally stops and everyone starts talking, thinking and dreaming about a single thing: the Stanley Cup Playoffs. Even most of those who don’t normally care the least bit about hockey transform into die hard fans of the Montréal Ca

Python for Signal Processing
Random walks are a gold mine for a wide variety of stochastic theory and practice. They are easy to explain, easy to code, and easy to misunderstand. In this section, we start out with the simplest imaginable random walk and then show how things can go wrong. Note that this post is also available in nbviewer where the math below may render better than here in blogger. Let's examine the problem of
Adventures in Signal Processing with Python - Jason Sachs
Author’s note: This article was originally called Adventures in Signal Processing with Python (MATLAB? We don’t need no stinkin' MATLAB!) — the allusion to The Treasure of the Sierra Madre has been removed, in deference to being a good neighbor to The MathWorks. While I don’t make it a secret of my dislike of many aspects of MATLAB — which I mention later in this article — I do hope they can impro
