Look up any term in AI.

AI Safety

AI safety is three fields, not one: present-day reliability, alignment, and catastrophic risk. What each actually claims, and why they get confused.

Attention Mechanism

Each token emits a query, key and value; dot-product scores scaled by √d become softmax weights over every other token. The cost grows as n².

Underfitting

Underfitting is when a model is too simple to capture the real pattern, so it does poorly on both training and new data — the mirror of overfitting.

Quantum Computing (QC)

Quantum computing uses qubits — held in superposition and entangled — for exponential speedups on a narrow set of problems, not general computing.

Neurons

One neuron multiplies its inputs by weights, adds a bias and applies a function. The arithmetic worked by hand, and where the brain analogy breaks.

Recommendation Systems

A recommendation system predicts what a user will want — a film, product, or song — from patterns in past behavior, and surfaces it automatically.
