In the past decade, many authors replaced multivariate regression (MR) by the neural networks (NNs) algorithm because they believed the latter to be superior. To verify this, we …

An unsupervised learning method is proposed for variable selection and its performance assessed using three typical QSAR data sets. The aims of this procedure are to generate a …
Choosing a set of molecular descriptors (features) that is most relevant to a given biological response variable is a very important problem in QSAR that has not be solved in an optimal …
We improve a recently developed Replacement Method (RM) for the selection of an optimal set of molecular descriptors from a much greater pool of such regression variables. Our …
