Feature vector
A feature vector is an ordered collection of feature values that represents an instance for computational or statistical processing.

A feature vector is a numerical vector whose components encode properties of an input or intermediate representation.
- How it is used
- Uses feature vectors to encode image patches before quantizing visual representations into discrete sequences.
- How deep it goes
- Explains dimensions, spatial layout, codebook matching, index conversion, and reconstruction, but not vector-training mathematics.
- Examples
- Uses a cat image, a 24 × 24 latent grid, 256-value vectors, 1,024 codebook entries, and integer indices such as 873 and 862.
- What you can do after
- Apply VQGAN to inspect latent feature vectors, convert them into codebook indices, and reconstruct an image from those indices.

Graph Algorithms for Data Science
A feature vector is a vector whose numerical components encode selected characteristics of a data point or node.
- How it is used
- Encodes extracted user characteristics so similarity networks and user segments can be constructed.
- How deep it goes
- Explains vector use through cosine similarity and network construction, without detailing feature-extraction internals.
- Examples
- Uses Twitter users, extracted user characteristics, pairwise cosine similarity, and inferred user segments.
- What you can do after
- Apply it via cosine similarity to construct user-similarity networks and support community-based segmentation.
