Data Compression in AI encompasses techniques for reducing the size of datasets, models, and computational representations while preserving essential information and predictive performance. Key methods include model quantisation (reducing numerical precision of weights), pruning (removing redundant parameters), knowledge distillation (training compact student models from large teachers), and neural compression via autoencoders. These techniques are critical for deploying AI on resource-constrained edge devices and for reducing storage, bandwidth, and energy costs.

Overview
Data Compression in AI involves reducing the size of datasets, models, and computational representations while preserving essential information. Techniques include model quantization (reducing numerical precision), pruning (removing redundant parameters), knowledge distillation (training smaller models to mimic larger ones), and neural compression methods (autoencoders, learned compression). Data compression is critical for deploying AI on resource-constrained devices, reducing storage costs, accelerating inference, and minimizing energy consumption. Advanced approaches leverage entropy coding, sparsity exploitation, and learned representations for adaptive compression.
