Adaptive coding refers to a process in which the encoding or digitization of information is dynamically adjusted based on specific criteria or requirements. This approach allows for the efficient representation of data based on changing conditions or user preferences, such as available bandwidth or device capabilities. Adaptive coding techniques can improve the overall quality and performance of digital systems by tailoring the encoding process to suit specific needs and constraints. This research area is relevant in fields such as image and video compression, audio processing, and data transmission, where adaptive coding algorithms can help optimize data storage, transmission, and retrieval.
