http://matt.eifelle.com Tue, 22 Jul 2008 18:56:36 +0000 http://backend.userland.com/rss092 en Once the data set is reduced (see my first posts if you're jumping on the bandwagon), there are several ways of mapping this reduced space to the original space: you can interpolate the data in the original space based on an interpolation in the reduced space, or you create an approximation of ... http://matt.eifelle.com/2008/07/14/dimensionality-reduction-mapping-the-reduced-space-into-the-original-space/ After some general books on grid computation, I needed to change the subject of my readings a little bit. As Intel Threading Building Blocks always intrigued me, I chose the associated book. Content and opinions After a small introduction chapter (installation, the TBB philosophy of tasks instead of threads), the second chapter ... http://matt.eifelle.com/2008/07/09/book-review-intel-threading-building-blocks-outfitting-c-for-multi-core-processor-parallelism/ My manifold learning code was for some time a Technology Preview in the scikit learn. Now I can say that it is available (BSD license) and there should not be any obvious bug left.. I've written a small tutorial. It is not an usual tutorial (there is a user tutorial and ... http://matt.eifelle.com/2008/06/27/dimensionality-reduction-the-scikit-is-available/ Peer-to-peer. These words are unleashing in France a fight between the legislators and the developers. And this old - I say old because it was written in 2001, and 7 years is old for a book on this topic - book presented me the issues debated in journals, blogs, ... ... http://matt.eifelle.com/2008/06/17/book-review-peer-to-peer-harnessing-the-power-of-disruptive-technologies/ At last, my article on manifold learning has been published and is accessible with doi.org (it was not the case last week, that's why I waited before publishing this post). The journal is free, so you won't have to pay to read it : Access to the EURASIP JASP article I will ... http://matt.eifelle.com/2008/06/11/a-metric-multidimensional-scaling-based-nonlinear-manifold-learning-approach-for-unsupervised-data-reduction/ Today, I'm publishing a tutorial on two C++ profilers on my French website. The question I'm asking myself and you is: should I translate it ? If some of you are interested in my French tutorials, I may translate them from time to time, depending on their content (I don't want ... http://matt.eifelle.com/2008/06/03/to-translate-or-not-to-translate/ Since the beginning of this year, I was trying to figure out what to do in my future. I'm still doing my PhD, but what could I do after that ? Before My current job is to find a model for datasets. A lot of datasets can be explained by a small number ... http://matt.eifelle.com/2008/05/27/a-new-future/ I was looking for an introductory book on peer-to-peer (P2P) application and their application to grid computation. Web services was a bonus, as it is something I don't usually play with. Content and opinions The book is split in four parts. The first chapter is an introduction to distributed systems, with the ... http://matt.eifelle.com/2008/05/06/book-review-from-p2p-to-web-services-and-grids-peers-in-a-clientserver-world/ I've noticed some days ago that I mainly used one design pattern in my scientific (but not only) code, the registry. How does it work? A registry is a list/dictionary/... of objects, applications add a new entry if it is needed, and then a user can tap into the registry ... http://matt.eifelle.com/2008/04/30/my-favorite-design-pattern-in-python/ This book is different from the two last books I read. Indeed, it tackles a specific Python library, Twisted, and how to use it. Content and opinions Twisted is a network library aiming at simplifying the developement of network applications. It is based on an event loop for all processing (unfortunately, no ... http://matt.eifelle.com/2008/04/28/book-review-twisted-networking-programming-essentials/
