NoSQL
Non‑relational databases such as key‑value stores used by nodes and indexers for performance.
Non‑Determinism
Behavior that can vary run‑to‑run, avoided in smart contracts to keep consensus deterministic.
Nullifier
Unique value derived in privacy protocols to prevent double spending while preserving anonymity.
Non‑Inclusion Proof
A proof that a key or value is not present in a set or Merkle structure.
Named Entity Recognition
Task of labeling spans in text as people, organizations, places, or other entity types.
Normalization
Techniques like batch norm or layer norm that stabilize and speed up training.
Neural Network
Parameterized function composed of layers and non‑linearities trained by gradient descent.
NeRF (Neural Radiance Fields)
Neural representation that models 3D scenes from 2D images for novel view synthesis.
Negative Sampling
Training trick that samples incorrect targets to approximate softmax or learn contrasts efficiently.
Nearest Neighbor Search
Indexing and retrieval to find closest vectors in embedding space, used in RAG and similarity search.
