A Fuzzy-Logic and Multi-Layer Perceptron Hybrid Model Applied to a Real World Steel-Making Problem
Yannick Lallement, Frédéric Alexandre · 1998
: One of the most interesting properties of neuro-symbolic hybrid models is that they allow for the combination of knowledge-based and data-based approaches. We have used such a strategy in a large, complex steel-making problem. We present this problem together with one of the hybrid models that have been tested on it. We choose to describe this hybrid in details because it is representative of such data-knowledge integration. 1 Introduction From 1994 to 1997, the European project MIX has been working on neuro-symbolic hybrid models. Its goal was to better understand this approach, investigate strategies and create tools for a better implementation of neurosymbolic coupling. This work was assessed on three real world applications, including a steel-making application. Several hybrid models have been tested on this latter application and a combination of these hybrids has been chosen and implemented on-line in the steel plant. In this paper, we first present the application and two pr...
