First European Summer School on Artificial Intelligence (ESSAI) and Twentieth Advanced Course on Artificial Intelligence (ACAI)

Organized jointly as Third TAILOR Summer School on Artificial Intelligence

24–28 July, 2023, Ljubljana, Slovenia

Under the auspices of:


Financially supported by:


Organized by:

University of Ljubljana     University of Primorska     Jozef Stefan Institute


ESSAI & ACAI-2023 follow on the footsteps of ACAI (Advanced Course on AI) and the TAILOR Summer School on AI. ACAI is organized since 1985 under the auspices of EurAI, The European Association for Artificial Intelligence, and ACAI-2023 will be its 20th edition. The TAILOR Summer School on AI is associated with the EU Project TAILOR (Foundations of Trustworthy AI – Integrating Reasoning, Learning and Optimization). Its first edition in 2021 was standalone and virtual and in 2022 it was organized in Barcelona together with ACAI. This third edition is special as it grows into ESSAI-2023, The First European Summer School on AI.

ESSAI & ACAI-2023 will take place at the Faculty of Computer and Information Science, University of Ljubljana. They will comprise 30 courses/ tutorials, presented in six parallel tracks. ACAI-2023 will offer 10 invited tutorials (of 2x90min each) on the topic of AI & Science, while ESSAI-2023 will offer 20 courses (of 5x90min each) on all topics of AI, solicited through an open call for course proposals and selected by an international program committee.


ESSAI-2023 will take place at the Faculty of Computer and Information Science, University of Ljubljana. It will have five parallel tracks, each comprising four courses. Each course will consist of five 90 min sessions (one on each day during the week). A total of 20 courses will be included in ESSAI, to be selected among the proposals solicited by this call.

The European Summer School in Artificial Intelligence (ESSAI) is a new annual summer school held under the auspices of the European Association for Artificial Intelligence (EurAI). ESSAI builds on initiatives of the EU project TAILOR, and the 1st edition of ESSAI is simultaneously the 3rd edition of the TAILOR Summer School. The ambition of ESSAI is to become the central meeting place for students and young researchers in Artificial Intelligence to discuss current research and share knowledge.

ESSAI will provide an interdisciplinary setting in which courses are offered in all areas of Artificial Intelligence and also from wider scientific, historical, and philosophical perspectives. The format of ESSAI is analogous to the European Summer School in Logic, Language and Information (ESSLLI), which has been running since 1989. Courses will consist of five 90-minute sessions, offered daily (Monday-Friday) in a single week, to allow students to develop in-depth knowledge of a topic.

Important dates

  • 24 Jan 2023: Course title submission (mandatory) deadline
  • 31 Jan 2023: Final submission
  • 28 Feb 2023: Notification

Topics and format

ESSAI aims to cover all sub-disciplines of AI and the interactions between them.

Proposals for courses at ESSAI 2023 are invited in all areas of Artificial Intelligence, including but not limited to the following:

  • Agent-based and Multi-agent Systems (MAS)
  • Ethics, Legal Issues, Explainable and Trustworthy AI (XAI)
  • Knowledge Representation and Reasoning (KR)
  • Natural Language Processing (NLP)
  • Neuro-Symbolic Learning and Reasoning (NeSy)
  • Planning & Strategic Reasoning (PLAN)
  • Reinforcement Learning (RL)
  • Robotics (ROB)
  • Search & Optimization (SO)
  • Supervised and Unsupervised Learning (ML)
  • Vision (VIS)
Each course will consist of five 90 minute lectures, offered daily (Monday-Friday) in a single week.


Each proposal should fall under one of the following categories: foundational, introductory or advanced course.

* Foundational courses *

Foundational courses present the basics of a research area to the students with no prior knowledge in that area. They should be at an elementary level, without prerequisites in the course’s topic, though possibly assuming a level of general scientific maturity in the relevant discipline. They should enable researchers from related disciplines to become comfortable with the fundamental concepts and techniques of the course topic, thereby contributing to the interdisciplinary nature of our research community.

* Introductory courses *

Introductory courses are central to ESSAI’s mission. They are intended to introduce a research field to students, young researchers, and other non-specialists, and to foster a sound understanding of its basic methods and techniques. Introductory courses should enable researchers from related disciplines to become competent in the course topic. Introductory courses that are cross-disciplinary may presuppose general knowledge of the relevant disciplines.

* Advanced courses *

Advanced courses are targeted primarily at graduate students who wish to acquire an understanding of current research in a field of Artificial Intelligence.

Proposal guidelines

To be considered, course proposals should closely adhere to the following guidelines:

  • Course proposals must be submitted by the lecturers who will present the course. Normally, a course should have no more than two or three lecturers, and each lecturer should hold a PhD or equivalent degree.
  • Course proposals should explicitly state the intended course category. Proposals for introductory courses should indicate the intended level, for example, as it relates to standard textbooks and monographs in the area. Proposals for advanced courses should specify the prerequisites in detail.

Proposals must be submitted in PDF format via: https://easychair.org/conferences/?conf=essai2023 and include all of the following:

  1. Personal information for each proposer: Name, affiliation, contact address, email, homepage (optional)
  2. General proposal information: Title, category
  3. Information about the course content:
    • Abstract of up to 150 words
    • Motivation and description (up to two pages)
    • Tentative outline
    • Expected level and prerequisites
    • Appropriate references (e.g. textbooks, monographs, proceedings, surveys)
  4. Information about the proposer(s) and course:
    • Proposers’ experience of delivering courses in an intensive interdisciplinary setting
    • Evidence that the proposers are excellent lecturers
    • Where there is more than one lecturer, the role of each lecturer and their teaching commitment to the course should be specified
  5. To keep participation fees to a minimum, all the instructional and organizational work of ESSAI is performed on a completely voluntary basis. However, the registration fees of organizers and instructors will be waived, and travel and accommodation expenses will be reimbursed up to a level which will be communicated along with the proposal notification. ESSAI can only guarantee reimbursement for at most one course lecturer, and can not guarantee full reimbursement of travel costs for lecturers from outside of Europe. The organizers of ESSAI would appreciate any help in reducing the School’s expenses by seeking partial or complete coverage of travel and accommodation expenses from other sources.

    Submission information

    By Jan 24, 2023:
    Proposers must submit on EasyChair at least the name(s) of the lecturers(s), the ESSAI area+course level and a short abstract.
    By Jan 31, 2023:
    Submission must be completed by uploading a PDF with the actual proposal as detailed above.
