Predicting age and maturity of endangered Spiny butterfly ray, Gymnura altavela (Linnaues 1758) using artificial neural network (multilayer perceptron)
Abstract
The data were derived from several sources, including 338 records of maturity, age, and disc width of the Spiny butterfly ray (Gymnura altavela). An artificial neural network (Multilayer Perceptron) model (1, 10, 2) was used to predict the maturity and age of the Spiny butterfly ray, which is a high-accurate model with excellent efficiency. This network shortens the time, effort and cost compared to traditional methods or a convolutional neural network (CNN) in age prediction. Therefore, we can predict the maturity and age of individuals without killing or harming them, just by getting simple data (disc width) and inter it into the updated model from the network. This network allows us to obtain valuable data for use in studying stock indicators of endangered Spiny butterfly ray without compromising their factual stock.
