Résumé
They matter because they gave deep learning one of its first principled, sampleable models of data — powering image generation, anomaly detection, and the latent spaces inside modern diffusion models.

What is Variational Autoencoders?
Autoencoder yu bari (VAEs) ay reso neuronal yuy defar ay reso yuy jàng kompresse ay done ci barab bu nëbbu bu nooy, ba noppi defaraat wala defar ay misaal yu bees ci. Dañu am solo ndax dañu jox njàng mu xóot benn ci xeeti done yu njëkk yi, yuñ mëna jël misaal - defar nataal yu am doole, gis anomali, ak barab yu nëbbu yi ci biir xeeti diffusion yu bees yi.
Lan mooy encoder bi ci VAE biy génne ci benn duggal buñ jox?
Encodeur VAE wuute na ak autoencodeur bi, ndax encodeur VAE dafay génne ay parametru séddale (dafay nuru moyenne ak variance Gaussian), suko defee ñu jël benn poñ ci séddale boobu.
