❓ Frequently Asked Questions
What is neural network compression?
A set of techniques to shrink model size and computational cost, so networks run faster and use less memory.
Why is compression important for devices with limited resources?
It reduces memory, energy use, and latency, enabling deployment on smartphones, wearables, and edge devices.
What are common compression techniques?
Pruning, quantization, knowledge distillation, low-rank factorization, and weight sharing.
What is quantization?
Reducing the precision of weights and activations (e.g., from 32-bit to 8-bit) to shrink size and speed up inference with minimal accuracy loss.
What is pruning?
Removing less important weights or neurons to reduce parameters and computations; can be unstructured (sparse) or structured (removing whole units).
