Transitive inference as probabilistic preference learning

no code implementations23 Nov 2023 Francesco Mannella, Giovanni Pezzulo

We propose a novel framework that casts TI as a probabilistic preference learning task, using one-parameter Mallows models.

Modeling motor control in continuous-time Active Inference: a survey

no code implementations8 Oct 2023 Matteo Priorelli, Federico Maggiore, Antonella Maselli, Francesco Donnarumma, Domenico Maisto, Francesco Mannella, Ivilin Peev Stoianov, Giovanni Pezzulo

This article provides a technical illustration of Active Inference models in continuous time and a brief survey of Active Inference models that solve four kinds of control problems; namely, the control of goal-directed reaching movements, active sensing, the resolution of multisensory conflict during movement and the integration of decision-making and motor control.

Bridging Cognitive Maps: a Hierarchical Active Inference Model of Spatial Alternation Tasks and the Hippocampal-Prefrontal Circuit

no code implementations22 Aug 2023 Toon Van de Maele, Bart Dhoedt, Tim Verbelen, Giovanni Pezzulo

Through a series of simulations, we demonstrate that the model's dual layers acquire effective cognitive maps for navigation within physical (HC map) and task (mPFC map) spaces, using a biologically-inspired approach: a clone-structured cognitive graph.

Integrating cognitive map learning and active inference for planning in ambiguous environments

no code implementations16 Aug 2023 Toon Van de Maele, Bart Dhoedt, Tim Verbelen, Giovanni Pezzulo

Living organisms need to acquire both cognitive maps for learning the structure of the world and planning mechanisms able to deal with the challenges of navigating ambiguous environments.

Integrating large language models and active inference to understand eye movements in reading and dyslexia

1 code implementation9 Aug 2023 Francesco Donnarumma, Mirco Frosolone, Giovanni Pezzulo

We present a novel computational model employing hierarchical active inference to simulate reading and eye movements.

World Models and Predictive Coding for Cognitive and Developmental Robotics: Frontiers and Challenges

no code implementations14 Jan 2023 Tadahiro Taniguchi, Shingo Murata, Masahiro Suzuki, Dimitri Ognibene, Pablo Lanillos, Emre Ugur, Lorenzo Jamone, Tomoaki Nakamura, Alejandra Ciria, Bruno Lara, Giovanni Pezzulo

Therefore, in this paper, we clarify the definitions, relationships, and status of current research on these topics, as well as missing pieces of world models and predictive coding in conjunction with crucially related concepts such as the free-energy principle and active inference in the context of cognitive and developmental robotics.

Interactive inference: a multi-agent model of cooperative joint actions

no code implementations24 Oct 2022 Domenico Maisto, Francesco Donnarumma, Giovanni Pezzulo

These simulations illustrate that interactive inference supports successful multi-agent joint actions and reproduces key cognitive and behavioral dynamics of "leaderless" and "leader-follower" joint actions observed in human-human experiments.

Information-theoretical analysis of the neural code for decoupled face representation

no code implementations22 Aug 2022 Miguel Ibáñez-Berganza, Carlo Lucibello, Luca Mariani, Giovanni Pezzulo

Processing faces accurately and efficiently is a key capability of humans and other animals that engage in sophisticated social tasks.

Skilled motor control implies a low entropy of states but a high entropy of actions

no code implementations22 Dec 2021 Nicola Catenacci Volpi, Martin Greaves, Dari Trendafilov, Christoph Salge, Giovanni Pezzulo, Daniel Polani

The mastery of skills such as playing tennis or balancing an inverted pendulum implies a very accurate control of movements to achieve the task goals.

Active Inference Tree Search in Large POMDPs

no code implementations25 Mar 2021 Domenico Maisto, Francesco Gregoretti, Karl Friston, Giovanni Pezzulo

Here, we introduce a novel method to plan in POMDPs--Active Inference Tree Search (AcT)--that combines the normative character and biological realism of a leading planning theory in neuroscience (Active Inference) and the scalability of tree search methods in AI.

Moral decisions in the age of COVID-19: your choices really matter

1 code implementation15 Apr 2020 Francesco Donnarumma, Giovanni Pezzulo

The moral decisions we make during this period, such as deciding whether to comply with quarantine rules, have unprecedented societal effects.
