Title
Treatment of Gradual Knowledge Using Sigma-Pi Neural Networks
Abstract
This work belongs to the field of hybrid systems for Artificial Intelligence (AI). It concerns the study of "gradual" rules, which makes it possible to represent correlations and modulation relations between variables. We propose a set of characteristics to identify these gradual rules, and a classification of these rules into "direct" rules and "modulation" rules. In neurobiology, pre-synaptic neuronal connections lead to gradual processing and modulation of cognitive information. While taking as a starting point such neurobiological data, we propose in the field of connectionism the use of "Sigma-Pi" connections to allow gradual processing in AI systems. In order to represent as well as possible the modulation processes between the inputs of a network, we have created a new type of connection, "Asymmetric Sigma-Pi" (ASP) units. These models have been implemented within a pre-existing hybrid neuro-symbolic system, the INSS system, based on connectionist nets of the "Cascade Correlation" type. The new hybrid system thus obtained, INSSGradual, allows the learning of bases of examples containing gradual modulation relations. ASP units facilitate the extraction of gradual rules from a neural network.
