quantization
Dividing into steps
Quantization is the process of restricting something continuous to discrete values.
In physics, it refers to the discovery that energy, light, and other phenomena exist in indivisible units (quanta) rather than smooth gradations—a foundation of quantum mechanics.
In digital signal processing, quantization converts analog signals to digital by mapping continuous amplitudes to fixed levels: The audio compression relies on quantization.
In machine learning, quantization reduces model precision to shrink file sizes and speed computation.
