Vector Quantization

Vector quantization is a technique used to simplify and compress data by grouping similar information into predefined categories called "code vectors." Imagine having a large set of points that represent detailed data; vector quantization replaces each point with the closest representative point from a smaller set of predefined options. This process reduces the amount of data needed to describe the original information, making it easier to store or transmit, while still maintaining the essential features. It’s commonly used in applications like image compression and signal processing to efficiently handle complex data.
