= Variance Adaptive Quantization
{wiki=Variance_Adaptive_Quantization}
Variance Adaptive Quantization (VAQ) is a technique used in signal processing and digital communication systems, particularly in the context of compression and encoding of data, such as images, audio, and video. The fundamental goal of VAQ is to adaptively adjust the quantization levels based on the variance or statistical properties of the input signal. \#\#\# Key Concepts 1. **Quantization**: This is the process of mapping a large set of input values (e.g.
