PyConUK 2013

I’m just finishing with PyConUK, it has been a fun 3 days (and the sprints carry on tomorrow). Yesterday I presented a lightly tweaked version of my Brand Disambiguation with scikit-learn talk on natural language processing for social media processing. I had 65 people in the room (cripes!), 2/3 had used ML or NLP for […]

Some Natural Language Processing and ML Papers

After I spoke at DataScienceLondon in June I was given a set of paper references by a couple of people (the bulk were by Levente Török) – thanks to all. They’re listed below. Along the same lines I have one machine learning paper aimed at beginners to recommend (“A Few Useful Things to Know about […]

Visualising London, Brighton and the UK using Geo-Tweets

Recently I’ve been grabbing Tweets some some natural language processing analysis (in Python using NetworkX and NLTK) – see this PyCon and PyData conversation analysis. Using the London dataset (visualised in the PyData post) I wondered if the geo-tagged tweets would give a good-looking map of London. It turns out that it does: You can […]

Analysing #pydata, London and Brighton tweets for concept mapping

Props to Maksim for his Social Media Analysis tutorial for inspiration. Update – Maksim’s Analying Social Networks tutorial video is online. For the earlier #PyCon […]

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

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 […]

If you’re not sure what I’m talking about then these 30 second demo […]
