## Description

- PL: Różne sposoby uczenia rozkładu i generowania próbek.
- EN: Different ways of learning a distribution and sampling from it.

## In one sentence

- PL: To różne rodziny modeli uczących się na przykładach, żeby tworzyć nowe obrazy, dźwięki lub inne dane.
- EN: These model families learn from examples to generate new images, sounds or other data.

## Problem it solves

- PL: Potrzebujesz nowych wariantów treści, a samo rozpoznawanie istniejących przykładów ich nie przygotuje.
- EN: You need new content variations, and recognising existing examples alone cannot produce them.

## What it does

- PL: Modele poznają wzory danych, a potem tworzą próbki przez odszumianie, przekształcanie losowych liczb, dekodowanie lub współpracę rywalizujących sieci.
- EN: Models learn data patterns, then generate samples through denoising, transforming random numbers, decoding or interacting networks with competing objectives.

## Everyday example

- PL: Tworzysz kilka wzorów tapety, a różne generatory proponują nowe układy na podstawie poznanych obrazów.
- EN: You create wallpaper designs, and different generators propose new layouts based on images they have learned from.

## This concerns you if you…

- PL: chcesz zrozumieć różnice między generatorami
- PL: potrzebujesz tworzyć nowe warianty danych
- EN: want to understand differences between generators
- EN: need to create new data variations

## Keywords

autoregressive models · diffusion models · VAE · GAN · normalizing flows · flow matching · latent variable models · likelihood estimation

## How it works

- PL: Trening dopasowuje rozkład danych przez wiarygodność, ograniczenie wariacyjne, grę przeciwstawną lub uczenie transportu i odszumiania. Próbkowanie korzysta potem z autoregresji, dekodera, odwracalnych przekształceń albo iteracyjnej ścieżki od szumu do danych.
- EN: Training fits data distributions through likelihood, variational bounds, adversarial games or transport and denoising objectives. Sampling then uses autoregression, decoders, invertible transformations or iterative paths from noise to data.

## Limits

- PL: Jakość i różnorodność próbek zależą od danych oraz celu. Wiarygodny wygląd nie zapewnia zgodności faktów; ocena rozkładu, koszt próbkowania i ryzyko zapamiętywania różnią się między rodzinami.
- EN: Sample quality and diversity depend on data and objectives. Plausible appearance does not ensure factual correctness; distribution evaluation, sampling cost and memorisation risks differ across families.

## Key terms

- PL: **rozkład generatywny**: Model prawdopodobieństw możliwych danych, z którego można uzyskiwać próbki.
- PL: **próbkowanie**: Losowe uzyskiwanie przykładów zgodnie z wyuczonym mechanizmem generowania.
- EN: **generative distribution**: A probability model of possible data from which samples can be obtained.
- EN: **sampling**: Randomly obtaining examples according to a learned generation mechanism.

## Subtopics (6 direct, 38 in total)

- [Autoenkodery wariacyjne (VAE) (Variational autoencoders (VAE))](https://aiatlasgraph.com/t/vae.md): A model with an encoder that compresses data into a latent distribution and a decoder that reconstructs it from samples; trained by maximising the evidence lower bound (ELBO) with the reparameterisation trick.

  - [Rozplątane reprezentacje (β-VAE) (Disentangled representations (β-VAE))](https://aiatlasgraph.com/t/betavae.md): A VAE variant with weight β>1 on the KL term, strengthening independence of latent variables at the cost of reconstruction quality.
- [Autoregresyjne generowanie obrazu i dźwięku (Autoregressive image and audio generation)](https://aiatlasgraph.com/t/argen.md): Models generating data as a sequence of elements (pixels, samples, tokens or scales), each conditioned on earlier ones; a rival and complement to diffusion.

- [Generatywne sieci przeciwstawne (GAN) (Generative adversarial networks (GAN))](https://aiatlasgraph.com/t/gan.md): Two networks trained in an adversarial game: a generator creates samples and a discriminator distinguishes them from real data; the discriminator's signal trains the generator to better match the data distribution.
