NIPS Workshop on Machine Learning Open Source Software 2006

Workshop on Machine Learning Open Source Software 2006

The NIPS workshop on Workshop on Machine Learning Open Source Software (MLOSS) will held in Whistler (B.C.) on the 8th or 9th of December, 2006.

Important Dates

  • Submission Date: October 28th, 2006
  • Notification of Acceptance: November 8th, 2006 - passed
  • Workshop date: December 9th, 2006



Open source tools have recently reached a level of maturity which makes them suitable for building large-scale real-world systems. At the same time, the field of machine learning has developed a large body of powerful learning algorithms for a wide range of applications. Inspired by similar conferences in bioinformatics (BOSC) or statistics (useR), our aim is to build a forum for open source software in machine learning.

The workshop's goal is to foster a vibrant community that provides a viable open source machine learning environment. Ultimately, open source machine learning software should be able to compete with existing commercial closed source solutions. Towards this end, it is not enough for us to just bring existing and freshly developed toolboxes and algorithmic implementations to people's attention, but to initiate further collaboration towards moving from isolated solutions to a collection of tools which are designed to work with one another. Far from requiring integration into a single package, we believe that this kind of interoperability can also be achieved in a collaborative manner, which is especially suited to open source software development practices.

The contributed talks are accompanied by a mandatory demonstration of the software, which in turn must adhere to an approved Open Source License.


The workshop will be a mixture of talks (including a mandatory demo of the software) and panel/open/hands-on discussions.

Program Commitee

Call for Contributions (closed)

The organizing committee is currently seeking abstracts for talks at MLOSS 2006. MLOSS is a great opportunity for you to tell the community about your use, development, or philosophy of open source software in machine learning. This includes (but is not limited to) numeric packages (as e.g. R,octave,numpy), machine learning toolboxes and implementations of ML-algorithms. The committee will select several submitted abstracts for 20-minute talks. Accepted abstracts will be published on this web site.

If you are interested in speaking at MLOSS, please send us an email at before October 28th, 2006:

  • an abstract (1 page A4)
  • a URL for the project page, if applicable
  • information about the open source license used for your software or your release plans.

Note: Submissions must adhere to a recognized Open Source License (cf. ) and the source code must be available at the time of presentation.



The workshop is supported by PASCAL (Pattern Analysis, Statistical Modelling and Computational Learning)
