What is the decoder in autoencoders?
Updated May 5, 2026
Short answer
The decoder reconstructs the original input from latent space.
Deep explanation
It maps compressed latent representation back to original input dimensions. It learns to recover lost information during encoding.
Real-world example
Used in image denoising applications.
Common mistakes
- Using decoder without encoder training.
Follow-up questions
- Does decoder add new information?
- Can decoder be symmetric to encoder?
