Artificial Intelligence for Electrical Percolation of AOT-based Microemulsions Prediction

Künstliche Intelligenz für die Vorhersage der elektrischen Perkolation von AOT-basierten Mikroemulsionen
A. Cid, G. Astray, J. A. Manso, J. C. Mejuto and O. A. Moldes


Different Artificial Neural Network architectures have been assayed to predict percolation temperature of AOT/i-C8/H2O microemulsions. A Perceptron Multilayer Artificial Neural Network with five entrance variables (W value of the microemulsions, additive concentration, molecular weight of the additive, atomic radii and ionic radii of the salt components) was used. Best ANN architecture was formed by five input neurons, two middle layers (with eleven and seven neurons respectively) and one output neuron. Root Mean Square Errors (RMSEs) are 0.18°C (R = 0.9994) for the training set and 0.64°C (R = 0.9789) for the prediction set.


Verschiedene künstliche neuronale Netzwerke (ANN) wurden geprüft, um die Percolationstemperatur von AOT/i-C8/H2O-Mikroemulsionen vorherzusagen. Ein mehrschichtiges Perceptron-ANN mit fünf Eingangsvariablen (der W-Wert der Mikroemulsionen, die Konzentration und das Molekulargewicht des Additivs, die Atomradien und die Ionenradien der Salzkomponenten) wurde eingesetzt. Das beste ANN wurde gebildet aus fünf Eingangsneuronen, drei Zwischenlagen (mit elf bzw. sieben Neuronen) und einem Ausgangsneuron. Die mittleren quadratischen Fehler (RMSEs) sind 0,018°C (R = 0,9994) für den Trainingstest und 0,64°C (R = 0,9789) für den Vorhersagetest.
