Musical retribution

10 June 2010 @ réclame

Lately, some friends of mine enlightened quite a few of my evenings at Paris, by playing music and — I should say — stubbornly making use of a fair amount of talent in doing so :).

Now, I guess the least I can do is to thank them by pointing at them from here:

Last but not least…

7 March 2010 @ réclame

… though probably not so far from least !

I’ve decided to give flickr a go. So, I’ve uploaded a few pictures over there, and took the occasion to do things a bit differently: less photos displayed and no album but genuine titles and tags.

Here is the link: http://www.flickr.com/photos/27247511@N04/

Hopefully this will give a bit more visibility to some of those pictures. We shall see…

Correlation does not imply causation

28 February 2010 @ sciences

I’m trying something new today: a small experiment falling in between programming and scientific litterature.

I’ve been interested in “literate programming” for quite some time now, without going any further though. But I recently found the tools that would make it actually practicable and decided to dive in.

So, I’ve implemented a very small Python module that illustrates the notion of autocovariance and autocorrelation and the way to compute them via Fourier transforms:

Literate MusingAutocorrelations

The subject is not new at all, but such measures are something that I had to re-implement (for image processing puproses) more than I’d like to in past years, and each possible implementation having its own statistical biases, it always takes time to remember all the tricky details. So, this new document should at least help (me) quickly find all the relevant info.

This was also a subject underpinning a big part of my PhD work… a PhD that I defended 2 years ago, is there some “causation” here ?

:)

For the technical side of things, the “tools” that helped me setup this “experiment” are essentially:

Some new photos

25 January 2010 @ créations

I’ve proceeded to a few changes on my photo gallery, and most notably added a few photos over there, including:

and water.
