Modeling sensorimotor habits with neuro-robotics [Poster]

Together with Ezequiel Di Paolo I presented this poster at ESCOP2011, we present some old and new preliminary results on evolutionary robotics to ground a richer notion of habit than the one currently used in cognitive psychology and neuroscience.

The Future of the Embodied Mind

We have just started the eSMCs Summer School entitled The Future of the Embodied Mind. The discussion is already taking place both online and during the conference. Check out the website for more information and resources. Very exciting discussions going on, also a lot of work but the outstanding quality of speakers and participants is worth the effort.

Systematicity of thought and systemicity of habits

I just got back from the workshop “Systematicity and the post-connectionist era“, where I presented a talk entitled “From systematicity of thought to systemicity of habits“. Congratulations to the organizers for this extraordinary experience.

My talk started by assuming the real challenge of systematicity for dynamical approaches. The work of René Thom and Jean Petitot on morphodynamics and cognitive grammars serves as a powerful framework to solve this problem. In the second part of the talk I defend a contemporary re-appraisal of the notion of habit within the Piagetian framework, with illustrations from evolutionary robotics.

Metastable dynamical regimes in oscillatory networks and sensorimotor loop

Santos, B., Barandiaran, X.E. & Husbands, P. (2011) Metastable dynamical regimes in oscillatory network modulated by an agent’s sensorimotor loop. Proceedings of the IEEE Symposium Series on Computational Intelligence 2011, Accepted.

New paper in collaboration with my PhD student Bruno Santos, the paper is based on a simulation of Evolutionary Robotics where the controller is a Kuromoto network of oscillators, metastable dynamic regimes of phase relation (phase locking and phase scattering) are analyzed in continuous recurrent interaction between the agent and its environment.

The adjustment-deployment dilemma in organism’s behaviour

Aguilera, M., Bedia, M.G, Barandiaran, X.E. & Serón, F. (2011) The adjustment-deployment dilemma in organism’s behaviour: theoretical characterization and a model. Proceedings of the IEEE Symposium Series on Computational Intelligence 2011, Accepted

    New paper in collaboration with Miguel Aguilera and Manuel Bedia (almost all credit should go to them), we shaped a problem of temporality of action that we named the adjustment-deployment dilemma which has received no formal treatment till now: how much time should I invest adjusting or improving an action and how much deploying or executing it?

    A minimal model of metabolism-based chemotaxis

    Egbert, M. D., Barandiaran, X. E., & Di Paolo, E. A. (2010). A Minimal Model of Metabolism-Based Chemotaxis. PLoS Comput Biol, 6(12), e1001004.

    We present the first model of metabolism-based chemotaxis that accomplishes chemotaxis without transmembrane receptors or signal transduction proteins, through the direct modulation of flagellar rotation by metabolite concentrations. The minimal model recreates chemotactic patterns found in real bacteria, illuminating some previous work metabolism-dependent chemotaxis. A nice example of the inpiration taken from an autonomous perspective on agency, linking metabolism and behaviour.

    Phylogeny of the notion of Habit

    Together with Ezequiel Di Paolo we embarked into a historical research on the notion of Habits as theoretical building blocks for cognitive science. Far from the simplified stimulus-response pairing conception of habits defended by behaviorism, we found that habits have long been a very rich conceptual category at the root of the sciences and philosophies of mind, until very recently. Here is a preliminary graph that summarizes some of our results (that would hopefully be published as a paper some time soon):

    Phylogeny of the concept of Habit. The graph is still under development but captures the most important trends.

    Postdoc at CREA – CNRS / Polytechnique and ISC-PIF, in Paris

    Already integrated in my new working environment: Paris! I have my base camp at CREA (Centre de Recherche en Épistémologie Appliquée), an interdisciplinary research center that is part of École Polytechnique and the CNRS, but I will also participate and collaborate at the Complex Systems Institute (ISC-PIF). I am already co-organizing the Theoretical Biology Seminars – Séminaire de Biologie Théorique, and I hope to start collaborating on cognitive science research soon.

    Behavioral Metabolution: the very idea

    The paper I wrote together with Matthew Egbert and Ezequiel Di Paolo got accepted and will be soon published at the Proceedings of the 12th International Conference on Artificial Life. It is entitled Behavioral Metabolution: Metabolism Based Behavior Enables New Forms of Adaptation and Evolution and it addresses, the evolutionary scale interaction between metabolism and behavior, using a simulation of a bacteria-like moving protocell whose behavioral architecture is constituted by metabolism itself.

    Homeostatic Plasticity in Robots

    I am presenting this poster at the CogSys2010 Conference in Zurich. The poster shows some results of a simulation model I developed long ago (almost 5 years ago!) on a reinforcement learning task with evolutionary robotics, using homeostatic plasticity on the CTRNN controllers. I am currently writing a paper with Ezequiel Di Paolo on the details of the simulation model. The agents are capable to display a developmental process (connection weights are initialized at value 0), to solve an operant conditioning task and display the spontaneous formation of habits.
