Contributor to MLlib, dedicated to scalable deep learning. A few years later, in 1989, a young French scientist Yann LeCun applied a backprop style learning algorithm to Fukushima’s convolutional neural network architecture. The convolutional neural network (CNN) is one of the most used deep learning models for image detection and classification, due to its high accuracy when compared to other machine learning algorithms. To begin, just like before, we're going to grab the code we used in our basic. Alexnet was introduced in ImageNet Classification with Deep Convolutional Neural Networks. Currently, most graph neural network models have a somewhat universal architecture in common.
