Abstract : This paper deals with incremental classification and its particular application to invoice classification. An improved version of an already existant incremental neural network called IGNG Incremental Growing Neural Gas is used for this purpose . This neural network tries to cover the space of data by adding or deleting neurons as data is fed to the system. The improved version of the IGNG, called I2GNG used local thresholds in order to create or delete neurons. Applied on invoice documents represented with graphs, I2GNG shows a recognition rate of 97.63%.
