The Free Energy Principle for Perception and Action: A Deep Learning Perspective

no code implementations13 Jul 2022 Pietro Mazzaglia, Tim Verbelen, Ozan Çatal, Bart Dhoedt

The free energy principle, and its corollary active inference, constitute a bio-inspired theory that assumes biological agents act to remain in a restricted set of preferred states of the world, i. e., they minimize their free energy.

LatentSLAM: unsupervised multi-sensor representation learning for localization and mapping

no code implementations7 May 2021 Ozan Çatal, Wouter Jansen, Tim Verbelen, Bart Dhoedt, Jan Steckel

Biologically inspired algorithms for simultaneous localization and mapping (SLAM) such as RatSLAM have been shown to yield effective and robust robot navigation in both indoor and outdoor environments.

Deep Active Inference for Autonomous Robot Navigation

no code implementations6 Mar 2020 Ozan Çatal, Samuel Wauthier, Tim Verbelen, Cedric De Boom, Bart Dhoedt

Active inference is a theory that underpins the way biological agent's perceive and act in the real world.

Learning Perception and Planning with Deep Active Inference

no code implementations30 Jan 2020 Ozan Çatal, Tim Verbelen, Johannes Nauta, Cedric De Boom, Bart Dhoedt

Active inference is a process theory of the brain that states that all living organisms infer actions in order to minimize their (expected) free energy.

Learning to Catch Piglets in Flight

no code implementations28 Jan 2020 Ozan Çatal, Lawrence De Mol, Tim Verbelen, Bart Dhoedt

To develop and test our method, we start with an easy to identify object: a stuffed Piglet.

Bayesian policy selection using active inference

no code implementations17 Apr 2019 Ozan Çatal, Johannes Nauta, Tim Verbelen, Pieter Simoens, Bart Dhoedt

Learning to take actions based on observations is a core requirement for artificial agents to be able to be successful and robust at their task.
