JUPYTER NOTEBOOK TUTORIAL FRANÇAIS FULL SIZE
Such deconvolution networks are necessary wherever we start from a small feature vector and need to output an image of full size (e.g. Besides learning about the autoencoder framework, we will also see the “deconvolution” (or transposed convolution) operator in action for scaling up feature maps in height and width. This property is useful in many applications, in particular in compressing data or comparing images on a metric beyond pixel-levelĬomparisons. The feature vector is called the “bottleneck” of the network as we aim to compress the input data into a smaller amount of features. Autoencoders are trained on encoding input data such as images into a smaller feature vector, and afterward, reconstruct it by a second neural network, called a decoder. In this tutorial, we will take a closer look at autoencoders (AE).
