AI Glossary: Letter "N"

Named Entity Recognition (NER) is an NLP task that identifies and classifies key elements in text documents into predefined categories (such as names of people, organizations, locations, dates, or product codes).

Needle In A Haystack (NIAH) is an evaluation benchmark designed to test a model's retrieval accuracy across long context windows. It works by inserting a single, specific fact (the needle) into a long, unrelated text document (the haystack) and prompting the model to retrieve it.

Neural Architecture Search (NAS) is an automated process for designing artificial neural networks. By defining a search space, search strategy, and performance metric, NAS algorithms automatically discover optimal layer configurations.

An Artificial Neural Network (ANN) is a computing system inspired by the biological neural networks that constitute animal brains, structured as layers of interconnected nodes that process inputs to produce outputs.

Natural Language Processing (NLP) is a subfield of computer science and AI concerned with the interactions between computers and human language. It involves training computers to process, analyze, and synthesize large amounts of natural language data.

NormalFloat4 (NF4) is an information-theoretically optimal quantile quantization data type for normally distributed data, designed to compress neural network weights to 4-bit precision without losing accuracy.

A Neural Processing Unit (NPU) is a specialized microprocessor circuit designed specifically to accelerate the execution of machine learning algorithms, commonly integrated into mobile SOCs and edge hardware.

NVIDIA is a pioneer of GPU computing, dominating the hardware market for AI acceleration, training, and inference with its high-performance Hopper and Blackwell architectures.
