Are LDA, QDA and SVM-rbf computationally less complex than ANN?
Also are these classifiers more generalizable for their performance than a NN?
If the detection range is in ng/ml but the reference range is in ug/ml for a molecule or protein in serum or plasma .how to dilute and what is the initial volume to be taken for quantitative analysis
