 Adaptive predictive coding

Adaptive predictive coding (APC) is a signal processing technique that is a variation of predictive coding, which aims to efficiently transmit or compress data by taking advantage of the temporal or spatial correlations present in the signal. It employs adaptive mechanisms to improve prediction accuracy based on previously received or processed data. ### Key Characteristics of Adaptive Predictive Coding: 1. **Prediction Model**: APC uses a model to predict future values of a signal based on past values.
