Relational model

Codd · 1969

Codd’s 1969 relational model is a formal specification—not software, not SQL, not a product. It defines data as tuples in relations, enforces consistency via logic, and insists all information be explicit. Real databases violate it daily. That gap is where data engineering begins.

Diffusion model

Diffusion models don’t generate images—they reverse entropy, one noisy step at a time.

Gaussian splatting

Gaussian splatting ditches ray-marching for splatting—and gains speed by abandoning geometry.

Generative adversarial network

GANs don’t model reality—they train a mimic to beat a critic.

LoRA (machine learning)

LoRA doesn’t shrink models—it shrinks the cost of changing them.

Reinforcement learning from human feedback

RLHF outsources ethics to annotators—and then optimises for their rankings, not their intent.

ImageNet

Fei-Fei Li

ImageNet is a foundational dataset infrastructure — not a model, not a tool, not a service. It succeeded by making scale measurable, not magical.
