Resumen
Computer-implemented method for increasing efficiency in image classification that comprises: obtaining a set of input images (11); obtain at least a first input tensor associated with at least a subset of the set of input images (12), perform a decomposition in higher order dynamic modes (HODMD) of the at least one first input tensor (13), obtaining a first tensor of higher order dynamical modes (14); obtain at least a first expanded set associated with at least a subset of the input image set (15). After partitioning the expanded (or enriched, or augmented) set (16), a convolutional neural network (CNN) (7') is trained using at least a subset of the expanded set, thus obtaining a classification tool (8') capable of classifying new images (9') associated with the input images.
