... Composition of feature vectors: Another lesson of Tab. 3 is that the effect of the com- position of the feature vectors can vary depend- ing both on the task and on the size of the fea- ture vector. ... of codebook vectors (10,20,50,90) and the initialisation proce- dure: during one set of runs, each class receives the same number of vectors, during the other, the number of codebook vectors ... ws/wspos/wspp tors are assigned proportionally to each class and deteriorates with the number of codebook vectors, a clear sign of overfitting. LVQ achieves a performance ceiling of 100% precision and...
