Peru has become one of the main producers of Hass avocado, in this aspect a fundamental stage is the classification, this situation led to the approach of this research work which aimed to design a model based on Artificial Neural Networks that allows the classification of said fruit considering as criteria the state of physiological maturity and the evaluation of the damages and defects that it presents, said considerations are contemplated in the Peruvian Technical Standard NTP 011.018-2018. In the initial stage, a controlled environment was designed with a cold-day light level, which allowed the acquisition of images, building a dataset of 310 labeled images, on which Data Augmentation was applied. Then we proceeded to define the parameterization of a convolutional neural network architecture, obtaining a CNN model on which 4 criteria were evaluated, the resolution of the input images, the number of convolution and pooling layers, the learning factor and the number of training seasons. Finally, the results obtained were shown, defining the resolution of the input images in 64 x 64 pixels, 3 convolution layers accompanied by pooling, with 3x3 and 2x2 masks respectively and with ReLU activation functions, then moving to a fully layer layer connected, which was connected to a hidden layer and this to the output layer, which consisted of 4 neurons under the One Hot Encoding representation, with a softmax activation function, and a learning factor of 0.001, using in its training 50 epochs. After evaluating the parameterized model, a correct identification of the Hass avocado images was achieved with an accuracy of 87.5%.
