I cannot find information in detail about autoencoder
What can I do with an autoencoder (and how can I do this), practically speaking?
What does the encoder (this part I think I understand) and a decoder (could not find much about this) part do? Can it for example show on an explainable way how patterns in the data are being represented?
I read some papers that say that it can be used to denoise the input, how does this work? (Am I changing the values of my input)
Is it true that an autoencoder can be also done with PCA (if we assume linearity)?
