📦 AI MODEL COMPRESSION

AI model compression focuses on adapting models for deployment on edge devices, where resources like processing power and memory are limited.

Quantization involves reducing the precision of numerical values within a model – typically lowering the bit depth used to represent weights and activations.

Unstructured pruning - removing individual weights (sparsity). Structu

Unstructured pruning removes individual weights from a neural network, creating sparsity. This can be applied across channels and layers.

Magnitude-based pruning identifies the smallest weight values and sets them to zero. Iterative pruning combined with fine-tuning helps maintain accuracy after removing weights – a technique often referred to as 'Lottery Ticket Hypothesis'.
