| SIPINA for Windows (SIPINA_W©) is a software wich can extract knowledge from data. SIPINA_W© learns from quantitative and qualitative data. It produces a lattice graph. The trees are a particular case of a lattice. SIPINA method is more general than ID3 and C4.5 methods. In this program, the Lattice graph issued from the learning step is translated in terms of productions rules and stored in a Knowlege Base System (KBS). SIPINA_W© analyses the rules and detects several anomalies such as redundancy, contradictions,... and cancels them. SIPINA_W© can merge many KBS and optimize the final KBS. The validation of the learning is perfomed via an inference engine. For that, first you choose a data file and a KBS and then SIPINA_W© predicts the membership class of the examples in the file. As the same manner, the generalisation is done on any other file. | | |
