WebAn autoencoder is a neural network which is trained to replicate its input at its output. Autoencoders can be used as tools to learn deep neural networks. Training an autoencoder is unsupervised in the sense that no labeled data is needed. The training process is still based on the optimization of a cost function. WebHá 2 dias · The 3x8x8 output however is mandatory and the 10x10 shape is the difference between two nested lists. From what I have researched so far, the loss functions need (somewhat of) the same shapes for prediction and target.
