- Autoencoders are unsupervised learning algorithms. Unlike other algorithms, autoencoders learn to reconstruct the input, that is, an autoencoder takes the input and learns to reproduce the input as an output.
-
We can define our loss function as a difference between the actual input and reconstructed input as follows:
Here, is the number of training samples.
- Convolutional Autoencoder (CAE) that uses a convolutional network instead of a vanilla neural network. In the vanilla autoencoders, encoders and decoders are basically a feedforward network. But in CAEs, they are basically convolutional networks. This means the encoder consists of convolutional layers and the decoder consists of transposed convolutional layers, instead of a raw feedforward network.
- Denoising Autoencoders (DAE) are another small variant of the autoencoder...
