EuroSciPy 2013 write-up

The conference is over, tomorrow I’m sticking around to Sprint on scikit-learn. As last year it has been a lot of fun to catch up with colleagues out here in Brussels. Here’s Logilab’s write-up. Yesterday I spoke on Building an Open Source Data Science company. Topics included how companies benefit from open sourcing their tools, […]

June project: Disambiguating “brands” in Social Media

Having returned from Chile last year, settled in to consulting in London, got married and now on honeymoon I’m planning on a change for June. I’m taking the month off from clients to work on my own project, an open sourced brand disambiguator for social media. As an example this will detect that the following […]

More Python 3.3 downloads than Python 2.7 for past 3 months

Since PyCon 2013 I’ve been in a set of conversations that start with “should I be using Python 3.3 for science work?”. Here’s a recent reddit thread on the subject. Last year I solidly recommended using Python 2.7 for scientific work (as many key libraries weren’t yet supported). I’m on the cusp of changing my […]

Semantic map of PyCon2013 Twitter Topics

Maksim taught a lovely Social Graph Analytics course at PyCon the day before I taught Applied Parallel Computing. I took his demo for a “poor mans LDA/LSI analysis” of a Twitter topic (rather than using full LDA it just uses co-incident hashtags) and added usernames to produce the plot below. Update – Analysing #pydata conference […]

PowerPoint: Brief Introduction to NLProc. for Social Media

For my client (AdaptiveLab) I recently gave an internal talk on the state of the art of Natural Language Processing around Social Media (specifically Twitter and Facebook), having spent a few days digesting recent research papers. The area is fascinating (I want to do some work here via my Annotate.io) as the text is so […]

Office social graph connectivity using NetworkX

I wanted an excuse to play with the Python NetworkX graph visualisation library and recently I joined AdaptiveLab to consult on some data science & visualisation problems. Thus formed the question – how were we all connected together? I figured that looking at who follows us all will yield a little insight into the people […]

Testing 3 modern face detection libraries (face.com, openCV, libccv)

As a research project months back Balthazar and I tested 3 modern face detection libraries (definitely see Balthazar’s write-up). Face.com had just been acquired by facebook, they had a great and free service which annotated not just face locations but also sex, age and emotion. We also tested OpenCV (popular and free) and the lesser […]

aMaking “from lxml import etree” work with virtualenv (Python)

Update – these steps are overly complicated and *unnecessary*! See fizyk and Marius’ comments below. I’ll leave this post just in case it helps anyone – hopefully anyone coming here will realise it isn’t hard (now) to install lxml, as long as the OS dependencies are installed I use virtualenv for all development. Recently I […]

Kinect depth maps and Python

I had the opportunity to play with a Kinect over the weekend, I wanted to test out depth mapping using the built in infra red cameras. Using a structured light approach is different to the stereopsis approach I was looking at with Kyran recently. Using the open source drivers for Ubuntu I quickly got the […]

Lean Processes in StartupChile (short talk this morning)

I gave a short talk this morning with Ryan Lou on the Lean Processes that a startup can use. For me I looked back on the start of ShowMeDo in 2005 (and now) and how we iterated using email, google groups, surveys and lots of discovery by talking to users. I then looked at how […]
