- Named Entity Recognition(also: NER)
- A natural language processing technique that identifies and classifies named entities in text into predefined categories such as person names, locations, organizations, quantities, and domain-specific terms. In accessibility applications, NER can be used to extract meaningful…
- Neural Network(also: Artificial Neural Network, ANN)
- A machine learning model inspired by the structure of biological neural networks in the brain, consisting of interconnected layers of nodes (neurons) that process information by adjusting weighted connections during training. In accessibility and assistive technology, neural…
- Neural Radiance Field(also: NeRF)
- An implicit neural representation of a 3D scene, introduced by Mildenhall et al. in 2020, in which a small neural network is trained to map any 3D coordinate and viewing direction to a colour and density value. Rendering is performed by volumetric ray marching through this…
- Neural Vocoder
- A deep-learning model that synthesises audio waveforms from intermediate acoustic representations such as mel-spectrograms or discrete speech units. Examples include HiFi-GAN, WaveNet, WaveGlow, and SoundStream. Neural vocoders have largely replaced classical signal-processing…
