Tools and experiments for hybrid neuro-symbolic processing

Symbolic and connectionist tools are widely used in the artificial intelligence (AI) domain. Both approaches report weaknesses to address the full range of capabilities required by this domain, and are often combined to overcome some limitations, but no extensive efforts have been done to give a wider view of the problem. More precisely, many ad hoc hybrid models were built from symbolic and connectionist tools, but little was said about the choice, integration and combination of such tools. Such was the goal of the European ESPRIT project MIX. We report the main conclusions of this project, together with its results on a real-world application
