The encoder compresses input data into a lower-dimensional latent space, and the decoder reconstructs the original input from that compressed representation. Training uses reconstruction loss (MSE) without labeled data. The latent space dimension is a key hyperparameter — Stable Diffusion, for example, achieves a 48x compression ratio using an autoencoder. Beyond compression, autoencoders are used for image denoising, inpainting, and object removal. A known limitation of MSE loss is that it can produce blurry outputs, which more advanced autoencoder variants address with adjusted loss functions. ## Full article daily.dev links to this article rather than hosting it.
