Generative AI and LLM glossary

Model Evaluation

Variance measures a model's sensitivity to fluctuations in the training data, contributing to overfitting when high.

Generative Models

A generative model that learns to represent data in a latent space using variational inference.

Retrieval

In AI search, a vector is a list of numbers that locates an item in embedding space so nearby vectors can be retrieved as similar.

Retrieval

A vector database stores embedding vectors and runs similarity search, usually with metadata filters and optional hybrid lexical queries.

Retrieval

Vector search retrieves semantically similar items by comparing embedding vectors rather than relying only on exact keyword overlap.

Data Analysis

Software applications used to create graphical representations of data.
