Abstract
Cognitive o oading is a common psychological process of using our body or physical environment to reduce the mental load of a cognitive task. Turning one's head to be able to read rotated text more easily, i.e., external normalization, is one example of this. While there are computational models that try to explain cognitive o oading, they still weakly address the role of action within the perception process. Recent works in active inference have used the free energy principle to build models that closely connect perception to action. Here, we propose two computational models (with and without explicit transition model) to model cognitive o oading, formulated under the free energy principle. To evaluate our model we created the active MNIST: the well known digits database but incorporating actions (e.g., rotation, translation, skew, etc). Results show, as a proof of concept, that our proposed model captures digits external normalization by inferring the correct action. This aids classi cation and context disambiguation when using prior information.
