Look up any term in AI.

Random Forest (RF)

A random forest averages many decision trees, each grown on a bootstrap sample and split on a random subset of features, to cut variance without adding bias.

Guardrails

A guardrail is a deterministic check around a model that can block, rewrite, or force a retry — external code you can test, unlike prompting a model to behave.

AI Agent

An AI agent is an LLM-powered system that plans, calls tools, and acts autonomously in a loop to finish multi-step tasks — not just answer questions.

Principal Component Analysis (PCA)

Principal Component Analysis (PCA) reduces dimensions by projecting data onto orthogonal directions of maximum variance, ranked by the variance each keeps.

AI Architecture

How a production AI system is assembled: retrieval, context assembly, the model call, tool execution, validation, logging and evaluation.

Generative AI

Generative AI learns the probability distribution its training data came from, well enough to draw new samples from it — not just sort inputs into classes.
