In data compression
, twin vector quantization is related to vector quantization
, but the speed of the quantization is doubled by the secondary vector analyzer.
By using a subdimensional vector space useless hyperspace will be destroyed in the process.
The formula for calculating the amount of destroyed hyperspace is:
Data compression
In computer science and information theory, data compression, source coding or bit-rate reduction is the process of encoding information using fewer bits than the original representation would use....

Vector quantization
Vector quantization is a classical quantization technique from signal processing which allows the modeling of probability density functions by the distribution of prototype vectors. It was originally used for data compression. It works by dividing a large set of points into groups having...
, but the speed of the quantization is doubled by the secondary vector analyzer.
By using a subdimensional vector space useless hyperspace will be destroyed in the process.
The formula for calculating the amount of destroyed hyperspace is:
- H(x) = 5.22 / 4m
