ELLIS-DDMLab Workshop 2023

ELLIS Alicante in Spain and the Dynamic Decision Making Laboratory (DDMLab) in the USA, have joined forces to create research collaborations on Human-Centered Artificial Intelligence (AI).

In the 2023 ELLIS-DDMLab 3-day workshop, researchers from both laboratories will come together to encourage and develop novel collaborations in the study of human-AI complementarity and the role of AI in human societies. This workshop will be held March 7-9, 2023 in Alicante, Spain.

The goal of this workshop is to generate new research ideas that will advance the foundational research of human-AI collaborations and interdependencies. At the end of this workshop, researchers from ELLIS and DDMLab would have determined concrete themes of collaboration between the two laboratories, which will be pursued in future search.

Dynamic Decision Making Laboratory

A private, global research university, Carnegie Mellon University stands among the world’s most renowned educational institutions, and sets its own course. Start the journey here. Over the past 10 years, more than 400 startups linked to CMU have raised more than $7 billion in follow-on funding. Those investment numbers are especially high because of the sheer size of Pittsburgh’s growing autonomous vehicles cluster – including Uber, Aurora, Waymo and Motional – all of which are here because of their strong ties to CMU. With cutting-edge brain science, path-breaking performances, innovative startups, driverless cars, big data, big ambitions, Nobel and Turing prizes, hands-on learning, and a whole lot of robots, CMU doesn’t imagine the future, they create it.

The Dynamic Decision Making Laboratory was founded in 2002 by Prof. Cleotilde Gonzalez. Initially supported by a grant from the Army Research Laboratories, the DDMLab is now a group fully funded by grants from research institutions. The focus of the DDMLab research is to develop theoretical understanding of the process by which humans make decisions in dynamic environments and to provide practical demonstrations of how this theoretical knowledge can be used to improve human dynamic decision making and general performance in a number of practical domains. At the DDMLab, they use cognitive computational models and laboratory experiments to help explain and predict how people make such decisions. They also develop recommendations for how people can make such decisions better. Their driving theory is the Instance-Based Learning Theory (IBLT), which in essence proposes that people make choices by retrieving the best outcomes from their past experience. The process involves:

  • Retrieve memories (instances) that resemble the current situation (instances are triplets: situation-decision-utility)
  • Filter memories according to their maximum experienced expected value (utility or blended value)
  • Evaluate and store new instances reflecting each possible option in the decision situation
  • Select the option with the maximum blended value


The event will take place March 7-9, 2023 in Alicante, Spain. Activities will take place from 9:30 to 17:00, Tuesday through Thursday.
