The seventh COSEAL Workshop is a forum for discussing the most recent advances in the automated configuration and selection of algorithms. It will take place on August 26 and 27, 2019 in Potsdam, Germany and is organized by Holger Hoos and Marius Lindauer as co-chairs and Tobias Friedrich and Torsten Schaub as local chairs.
The workshop will consist of posters and talks about late-breaking research and useful tools, discussions regarding intra- and international cooperation, and many opportunities to interact with other attendees. Note also that this COSEAL workshop will be co-located with the FOGA conference, which runs from 27-29th of August.
All inquiries should be done by email to email@example.com
Scope of the Workshop
The scope of the workshop includes, but is not limited to:
- Algorithm selection
- Algorithm configuration
- Algorithm portfolios
- Performance predictions and empirical performance models
- Bayesian optimization
- Hyperparameter optimization
- Automated machine learning (AutoML)
- Neural architecture search
- Algorithm and parameter control
- Explorative landscape analysis
- Programming by optimization
- Registration opens: April 4th
- Registration deadline: July 31st
- Talk/Poster abstract deadline: July 31st
- Workshop: August 26th and 27th
Registration for presenting your work and attending all talks is free. Registration for the joint FOGA/COSEAL social dinner on Tuesday evening is optional and costs 100€. We hope to cover the 100€ from external funding (see below “Individual COST support”).
If you would like to present some work at the conference, either as a talk or as a poster (format A1), we would appreciate it if you submit a proposal for your presentation as soon as possible but not later than by July 31st. If you only want to attend and participate in discussions, please also register early, as the number of seats is limited.
To register we have a 3 step process:
Registration for the workshop ( mandatory ) Registration for the social dinner on Tuesday evening (optional) Registration to present a poster or to give a talk (optional)
Please note that the deadline for all three registrations is July 31st 2019.
For the first and third registration, there is no immediate confirmation email.
Deadline extension for social dinner: 27th September
Catering Cost Support
Every event gets better with more coffee and cookies. For exactly this, we get so-called ‘local organizer support’ from COST, depending on the number of COST-registered participants. Unfortunately, COST only counts participants who (a) have created a COST profile, (b) have told us until August 20 which email address they used at e-COST, and (c) will sign the list of participants with a blue pen at the event. This is not required, but highly appreciated as it helps the event. Remember: this improves your own coffee!
Individual COST support
If you have difficulties to get your trip reimbursed from your home institution, you can get a flat rate fee of 100€ (for one hotel night) from COST after the event. This is completely optional and independent of the aforementioned local organizer support. If this is relevant for you, tick the appropriate box here.
