Quantization may refer to:
In physics, the process of restricting a physical quantity to discrete values (e.g., energy levels in quantum mechanics).
In digital signal processing, the mapping of continuous amplitude values to discrete levels (often as part of analog-to-digital conversion).
In mathematical physics, procedures that relate classical and quantum descriptions (often called “quantization” methods such as deformation or geometric quantization).
In machine learning, techniques that represent neural network weights/activations with reduced-precision discrete formats (e.g., int8).
