Abstract :
Model selection is important in deciding among competing computational models in many scientific research domains including in cognition processing. This paper presents an information geometric model selection criterion GMSC and shows its application in cognition. IGMSC computes the geometric complexity of the model by regarding the model space as the manifold and estimates the model-data geometric fitness by using the divergence between the true distribution and the asymptotic distribution, enduing complexity and fitness with clear geometric significance. The comparison experiment shows the effect of IGMSC in cognition
