Radial Basis Function (RBF) Network for Python

Python implementation of a radial basis function network. The basis functions are (unnormalized) gaussians, the output layer is linear and the weights are learned by a simple pseudo-inverse.

Making a video with mencoder from .png still images

Run this script in the folder where the .png images are stored. mencoder will create a avi video with the given framerate (fps).

Feed Forward Neural Networks for Python

This implementation of a standard feed forward network (FNN) is short and efficient, using numpy's array multiplications for fast forward and backward passes. The source code comes with a little example, where the network learns the XOR problem.

Proseminar Game Theory in SS 2010

Next semster, I offer a proseminar about Game Theory. We will cover both the classical game theory topics (zero-sum / non-zero sum games, nash equilibrium, minimax algorithm, ...) and some other, game-related topics (altruism, chess computers, back-gammon playing, reinforcement learning, ...). If you are a student at TUM and interested, here is the website.

PyBrain journal article accepted

Last week, our journal article promoting PyBrain has been accepted at the Journal of Machine Learning research. The pdf can be found on the publications page.

PyBrain 0.3 released

Today we announced the release of the latest version of our machine learning library in Python. PyBrain 0.3 is available for download on the website www.pybrain.org or directly on GitHub, where we host the project.

unsolicited email protection

Similar to the ingenius idea of spamgourmet, I programmed my own UCE (unsolicited commercial email) protection feature. Email addresses can be created on the fly (without setup), using a different keyword in front of the @ for a particular site, followed by a dot and the limit, like facebook.5@... Emails arriving at this address are collected by a catchall mailbox and then forwarded to my real email address, or not, if a certain limit (5 in this example) has been reached for this keyword.

ExperimentSuite on GitHub

My Python script to run experiments and collect data is now available in my github account. It is very generic and works with configuration files. You can run your experiments, kill them in between and continue where you left off. It is multi-core aware (you need python2.6 for this) and can run combinations of parameter ranges for you. All the results are logged in files and folders, and there is a little API that lets you quickly collect and analyse the data. If you want to check it out, just clone it and play around with it. Here's the link: http://github.com/rueckstiess/expsuite/

Snippets

I finished my snippets section, a collection of syntax-highlighted code fragments and tutorials. It contains both permanent ones (that others might be interested in as well) and temporary snippets, which are a good way of quickly exchanging clipboard contents over the web.

Publications on ICANN and ECML

Two publications from ICANN '08 and ECML '08 are now available as pdf. Check out the publications section. For the ECML publication, some demo videos are available on the projects page where a simulated robot arm catches a ball.

Student Projects

We are constantly looking for good students who want to work with us. There are lots opportunities: Bachelor and Master/Diploma Theses, SEPs, Research Assistant Positions (HiWi) and student projects ("Join-In"). If you could see yourself getting involved in our research group, contact me.
