Linear Polyethers as Additives for AOT-Based Microemulsions: Prediction of Percolation Temperature Changes Using Artificial Neural Networks

Linare Polyether als Additive in AOT-basierenden Mikroemulsionen: Vorhersage von Veränderungen der Percolationstemperatur mittels eines künstlichen neuronalen Netzwerks
Óscar Adrían Moldes , Antonio Cid , I. A. Montoya and Juan Carlos Mejuto


Predictive models based on artificial neural networks have been developed for the percolation threshold of AOT based microemulsions with addition of either glymes or polyethylene glycols. Models have been built according to the multilayer perceptron architecture, with five input variables (concentration, molecular mass, log P, number of C and O of the additive). Best model for glymes has a topology of five input neurons, five neurons in a single hidden layer and one output neuron. Polyethylene glycol model's architecture consists in five input neurons, three hidden layers with eight neurons in both first two and five in the last, and a neuron in the last output layer. All of them have a good predictive power according to several quality parameters.


Es wurden auf künstliche neuronale Netzwerke basierende Vorhersagemodelle für die Percolationsschwelle von AOT-basierenden Mikroemulsionen, denen entweder Glyme oder Polyethylenglykole zugesetzt wurden, entwickelt. Die Modelle wurden entsprechend der Multi-Layer-Perception-Architektur mit 5 Eingangsvariablen (Konzentration, Molmasse, log P, Anzahl der C- und der O-Atome des Additivs) gebaut. Das beste Modell für die Gylme hat eine Topologie von 5 Eingangsneuronen, 5 Neutronen in der einzelnen Hidden-Layer und ein Ausgangsneutron. Die Architektur des Polyethylenglykolmodells besteht aus 5 Eingangsneuronen, 3 Hiddenlayer mit 8 Neutronen in den ersten beiden und 5 in der letzten Layer und einem Neuron in der letzten Ausgangslayer. Alle lieferten eine gute Vorhersage entsprechend der verschiedenen Qualitätsparameter.
