Model compression is the family of techniques that reduce the size or computational cost of a trained machine learning model while preserving as much of its predictive performance as possible. It persists through standardized methods (quantization, pruning, knowledge distillation, low-rank factorization) documented in peer-reviewed research and implemented in production toolkits. The practice carves itself by distinguishing between lossy compression (which sacrifices accuracy for size) and lossless compression (which preserves accuracy at lower efficiency gains), and by specifying the target dimension — parameter count, memory footprint, inference latency, or energy consumption.

Definition
Why it is in scope
A human-made machine learning practice: the systematic reduction of a trained model's size, parameter count, or computational requirements while preserving predictive performance. Institutionalized through techniques like pruning, quantization, and distillation, it persists as a research field and engineering discipline.

knowledge distillation is a specific kind of model compression — per Law 9, a competent speaker would call knowledge distillation 'a model compression technique'. It compresses a large model into a smaller one by distilling knowledge.

Quantization is built and maintained for the sake of model compression: in ML it reduces precision of model parameters to shrink model size and speed up inference. Its designed purpose in the ML context is to compress models while preserving acceptable accuracy.
