Prediction of Cervical Lymph Node Metastasis in Carcinoma of Tongue Using SOM

Abstract

The purpose of this study was to predict lymph node metastasis in tongue cancer. The performance was inferior to prediction by the fuzzy reasoning performed in the past when it predicted using single SOM. The quality of the node of SOM is not uniform. There are the nodes which performs the right diagnosis, and the nodes which performs mistaken diagnosis. If the priority factors are given,to the variable of input data and 3 different models are created by SOM, 3 models can complement mutually and can raise a prediction performance.
