Generative AI47

How AI makes images, video and music, and how to use it. Diffusion, GANs, prompt engineering, negative prompts, seeds, upscaling: the terms you meet the moment you open an image generator.

AI Art

Pictures made with generative tools, and the debates around them

Beginner
AI Watermark

An invisible mark quietly embedded in what AI generates

Ethics Intermediate
Autoencoder

A structure that learns by shrinking data down and rebuilding it

Intermediate
Background Removal

Erasing a photo's background and keeping just the subject

Vision Beginner
Colorization

Adding fitting color to a black-and-white picture

Beginner
Consistency

Keeping the same subject looking the same across every shot

Intermediate
ControlNet

A device that pins an image's shape down with a rough sketch

Advanced
Deepfake

Fake video or audio where AI copies a real face or voice

Ethics Beginner
Denoising

Removing only the flecks mixed in, leaving the original untouched

Intermediate
Diffusion Model

Peeling away blur, layer by layer, until a picture appears

Intermediate
GANGenerative Adversarial Network

A maker and a checker compete, and both get better

Intermediate
Gaussian Splatting

A 3D scene held as millions of scattered color blobs

Advanced
Generative AI

AI that invents a result that never existed before

Beginner
Guidance Scale

The dial that decides how literally a request gets followed

Advanced
Image Captioning

Looking at a picture and writing what's in it as a sentence

Intermediate
Image-to-Image

Building a new picture starting from a given one

Beginner
Inpainting

Erasing part of a picture and filling it back in

Beginner
Interpolation

Filling the space between two points with several in-between steps

Intermediate
Latent Space

The place where compressed values end up sitting

Intermediate
Lip Sync

Fitting mouth shapes to the beat of a sound

Vision Intermediate
LoRA

Leaving the main body alone and training only a small add-on

Training Advanced
Mode Collapse

When the generator settles on one winning output and just repeats it

Advanced
Motion Capture

Turning body movement into a record of point locations

Vision Beginner
Music Generation

Turning a few lines of request into a finished piece of music

Beginner
Negative Prompt

The field for writing what shouldn't appear in the picture

Beginner
NeRFNeural Radiance Field

A 3D scene that answers with light for any spot and direction

Advanced
Noise

The blur mixed in — and also where generation starts

Beginner
Outpainting

Widening a picture's frame and drawing the new edges to match

Beginner
Prompt Adherence

The yardstick for whether a result matches what was requested

Intermediate
Prompt Engineering

Shaping an instruction so the result matches what you want

Beginner
Resolution

The number of dots a picture is made of

Beginner
Sampling Steps

The number of passes it takes to turn blur into a picture

Intermediate
Seed

The starting number that reproduces the same picture again

Beginner
Style Transfer

Keeping a picture's content and swapping only its surface look

Beginner
Synthetic Data

Practice data made up in place of the real thing

Evaluation Intermediate
Text Generation

Building text by looking ahead and adding the next piece

LLM Beginner
Text-to-Image

Making a picture out of what's written down

Beginner
Text-to-Video

Turning text or a photo into a moving scene

Beginner
TTSText-to-Speech

The technology that reads text out loud in a voice

Vision Beginner
U-Net

Shrinks an image down, then grows it back while recovering position

Architecture Advanced
Upscaling

Enlarging a picture by inventing the detail it never had

Beginner
Variation

Slightly different results pulled from the same request

Beginner
Variational Autoencoder

An autoencoder that remembers things as a range, not a point

Advanced
Vocoder

The part that turns a sound blueprint into an actual waveform

Vision Advanced
World Model

A model of how the world works that you can run before acting
