description: 'In this tutorial, we will take a closer look at autoencoders (AE).
10+
11+
Autoencoders are trained on encoding input data such as images into a smaller feature
12+
vector,
13+
14+
and afterward, reconstruct it by a second neural network, called a decoder.
15+
16+
The feature vector is called the "bottleneck" of the network as we aim to compress
17+
the input data into a smaller amount of features.
18+
19+
This property is useful in many applications, in particular in compressing data
20+
or comparing images on a metric beyond pixel-level comparisons.
21+
22+
Besides learning about the autoencoder framework, we will also see the "deconvolution"
23+
24+
(or transposed convolution) operator in action for scaling up feature maps in height
25+
and width.
26+
27+
Such deconvolution networks are necessary wherever we start from a small feature
28+
vector
29+
30+
and need to output an image of full size (e.g. in VAE, GANs, or super-resolution
31+
applications).
32+
33+
This notebook is part of a lecture series on Deep Learning at the University of
34+
Amsterdam.
