Welcome to the Collective Computational Unit (CCU)

The CCU handles computer science and infrastructure aspects for the Centre of the Advanced Study of Collective Behaviour. It constitutes a core facility that is responsible for providing technical platforms and support, algorithmic solutions, and software frameworks, and will be home to technicians and a number of funded student assistants as well as computer science students at all levels. As a collaborative research enterprise, we provide and develop algorithms for the analysis and visualisation of highly complex scientific data repositories. In particular, the focus is on efficient methods for tracking and measuring collectives, (semi) automated data analysis, data mining, numerical simulation and parameter estimation, and visual and interactive data exploration.

The CCU offers three types of project support:

Standard Problems can be approached using well-established software tools (such as Amira, MatLab, KNIME). The centre will provide help with using software packages to solve problems and offer additional expertise, if required. This help will be provided primarily by student research assistants.
Elaborate Problems require modifications to or plugins for software packages involving known algorithms. These problems will be handled by master’s students specialising in computer science, who will either be paid for the support they provide, or, if the problem is more scientific rather than just technical in nature, will be given the opportunity to work on it as part of their master’s thesis.
Special Problems cannot be solved using standard approaches or software. To address these kinds of problems, the centre will provide help with finding the right experts in computer science or mathematics and also offer collaboration in our own fields of expertise. Projects in need of more comprehensive and complex algorithmic solutions that exceed initial estimates will have to apply for doctoral or post-doctoral researchers via the centre’s open calls for projects. These researchers will receive support from the computational centre in the form of regular meetings in which algorithmic techniques will be discussed.

About this Wiki

This Mediawiki is intended to link the many challenging problems arising in data analysis for collectives to experts from computer science, and provide a global platform for discussion to which everyone can contribute. Over time, it will also become a knowledge base and reference for methods and expertise available in the CCU. In particular, it introduces and gives tutorials for using computational resources, code repositories and data storage for all members.

Remember a Wiki lives from the contributions of all members. In particular, please make ample use of the discussion page which is available for every individual page (see "Discussion" link on top for an example), and leave comments whenever you think you have something useful to add.

Important notice

The previous temporary domain name is deprecated and will lead to an insecure connection and some browser warnings, as the domain certificates to not match. The website has moved to

ccu.uni-konstanz.de

Note that it's still not the new server, but once it arrives, we can now just copy everything over without any issues.

We also have the final authentication systems in place now, which will give a single central account for this Wiki as well as for all other services of the CCU. If you already had an account on this Wiki, it has been switched to the new system, and you need to reactivate it:

please go to the account management page.
click "e-Mail" on top to request a password reset e-mail.
your user name was changed to the standard form <firstname.lastname>.
your e-Mail address is the same you used for initial registration.
after you get the mail, click the link to get back to account management, which prompts you to set a new password.
after changing the password, you should be able to access the Wiki under the new account. All previous edits have been merged under your new account name.

Note that new users have to go through a different signup process, see below. User account creation on this Wiki is now disabled.
