Information for speakers

Speakers will find below some information concerning their presentation at the ESANN conference.

[Oral presentations - poster presentations]

Oral presentations

  • A PC will be available in the room, installed witt Adobe Acrobat reader (version XI). If you need other viewers or software, we encourage you to bring your own laptop installed with the required software and files.
  • In any case (use of the room PC or your own laptop), please be in the conference room at least 20 minutes before the end of the last break before your session, in order to upload the files on the computer or to test the connection with your own laptop. Testing even more in advance is encouraged.
  • A beamer (data projector) connected to the PC is installed.
  • As in many conference rooms, the bottom of the screen is less visible for participants sitting in the back of the room; please design your slides accordingly.
  • An overhead (transparencies) projector is available too (on request). Transparencies should be used in lanscape orientation.
  • Authors have 20 minutes to present their contribution, including 5 minutes for questions.
  • Do not use too small fonts ; do not forget that you will show your presentation in a room sized for about 120 people!
  • Problems with computers, with the projector itself, or with the connection between them, may still happen. Even if it is "old-fashioned", t is always a good idea to bring a copy of your presentation on transparencies, as backup solution.


Please do not forget that the ESANN conference gathers researchers from various disciplines (neural networks, statistics, data analysis, machine learning, computational intelligence, biology, etc.).  Everyone cannot know everything; so probably many of the attendees do not know your research field.  

During your presentation, if you go straight to your specific development without taking time to explain the background, there is a risk that many attendees will not understand your point.  We thus strongly suggest you to take time during your presentation to explain what you did and why you did it (background, reasons to study this specific point, where your development could be used, etc.). 

The details on how you did your work are probably too much detailed to be presented orally in 15 minutes.  Please restrict yourself to the points that are necessary to understand what you did, but avoid too much details that will make your presentation too complicated. These details are contained in the proceedings, and anyone interested in your talk has the possibility to read them after the conference.

To make it more explicit: There is no hope that participants to a conference (ESANN or another one...) will understand and memorize the details of about 20 presentations/day during three days.  The purpose of oral presentations is then to arouse the interest of the participants to your work.  If you succeeded in convincing them that your work is interesting, they have the possibility too read more details in the proceedings and even to contact you personally for a deeper discussion. Oral presentations are thus complementary to the paper in the proceedings, and not a simple summary of it.

Specific suggestions
Unfortunately, too much presentations at conferences are of bad quality because of the slides. It is impossible to give here detailed rules on how to create good slides, because generic rules simply do not exist. But it is easy to give some "do" and "don't" tips...
  • choose an adequate number of slides; for a 15 minutes presentation, around 10 slides (including titles) is OK.
  • do not take several slides (and therefore several minutes...) to present concepts that everybody knows in the room (for example, do not remind the back-propagation algorithm in a conference about neural networks...).
  • on the contrary, do not include too much details in your presentation; never forget that your talk will be appreciated only if the participants understand it (at least at 90%)! Among all details that are contained in your paper, make a choice for your presentation and refer the participants to the proceedings for more details!
  • do not follow the logical order of your paper for the oral presentation. A typical example is when the paper ends with convincing applications of your new theory; in your presentation, begin with the examples: people will be much more interested in listening to the end of your talk!
  • even if your topic is a mathematical development, limit the number of equations in your slides to a minimum. Do not prove a theorem in your slides, but refer to the proceedings for a proof!
  • whenever it is possible, replace text and equations by illustrations. Yes, it takes much more time to prepare slides with illustrations, but often it is the only way to make your point understood in 15 minutes!
  • repeat your talk in front of several people having the same background as the participants to the conference. Try to find a few people having some knowledge in neural networks, but not in the topic of your paper (do not choose your co-authors...). And follow their advice!
  • In summary: use your commonsense to evaluate how your talk could be understood by the average participant to the conference (not by the specialist of your topic nor by the chief cook of the convention center...), and choose the content of your slides for this evarage participant!

Poster presentations

Size and layout of posters
  • Posters can occupy a maximum surface of 117 cm (height) x 87 cm (width). It is recommended to use large fonts and drawings to make the poster readable at a distance of about 80 cm. Do not use a photocopy of your paper...
  • Posters will be fixed on the panels with pins (pins will be provided). Please avoid the use of one heavy poster of the full size of the board, which may be difficult to fix with pins; posters on paper are easier to carry to the conference, and easier to fix to the boards, than plastic coated ones! Posters printed on a set of (preferably A3) sheets may be used too.

Hanging posters

Please read the ESANN programme to know if your poster will be presented on Wednesday, Thursday or Friday. Posters should be hanged before lunch time and removed at the end of the day, after the poster session.


Each poster will be introducedduring a plenary session by a one minute talk by its authors, in the form of a "spotlight". This means that you should use one slide only, showing what is your work, but not how it was done. The goal of the spotlight is to raise interest and attract participants to your poster, not to subsititue it.

The one-minute limit must be strictly followed. Therefore you should use one content slide only. Spotlights have to be sent in advance to the conference organization, in order to avoid switching computers or uploading files before or during the session. Plese respect the following guidelines:

  • send your spotlight by e-mail to as soon as possible, but in any case befoore Friday April 19, 2019;
  • the "subject" field of your e-mail should be "poster spotlight Wednesday 10h50 your_name", where of course you replace Wednesday by Thursday or Friday depending on the day of presentation of your poster, 10h50 by the time of presentation of your poster (see the program for information about date and time), and your_name by the name of the person who will present the spotlight;
  • the file must be a one-slide PDF file joined as attachement to your e-mail;
  • the name of the file itself should be "Wednesday_10h50_your_name.pdf" where you replace as above.
