The ISTC-CNR scenarios (some examples from D2.1)
• Guards and Thieves Scenario Task 1: Conflict in accessing the valuables (individual)
Model the shift between deliberative and automatic control of action Design a cognitive system that is able to exploit representations at different abstractions
(different *formats*?) Task 2: Conflict in accessing the valuables (social)
Identify different basis of prediction (i.e. mind-reading) Design a cognitive system that is able to help and to do critical help by anticipating other’s needs,
actions or capabilities, e.g. by removing obstacles or doing part of other’s work Design a cognitive system that is able to delegate by trusting
• Finding and Looking for Scenario Task 1: Finding a specific object
Recognition of objects from sensory flow on the basis of prediction Integration of sensory flow in time
Task 2: Finding members of a class of objects by class description Robustness with respect to contraction or expansions of sensory flow Abstraction

The predictive mechanismsPredictive Mechanisms
and typeUse in the Scenario Availability Status Partner
Forward model (based on Fuzzy Cognitive Maps)
- Learn to predict- Prediction of the next event at different level of abstraction (sensory input, consequence of action, direct experience, theory-based, indirect experience, simulation)
Prototype ISTC-CNR
Hebbian time rules - Predictive Learning Under development ISTC-CNR
Bayesian algorithms Assumption based Truth-Maintenance Systems (ATMS)
- Belief revision and update- Prediction based on abduction process- Expected utility
In progress ISTC-CNR
Neural Networks trained with supervised algorithms
- Prediction at a single temporal level- Approximation to noise
Prototype ISTC-CNR
Hierarchical Neural Networks trained with supervised algorithms
- Prediction at different temporal and spatial levels
