Neural Networks Compression Theory

bookLimits, Robustness, and Failure Modes

Understanding the theoretical limits of neural network compression is essential for developing efficient, reliable models. As you compress a neural network — by pruning parameters, quantizing weights, or distilling knowledge — there comes a point where further reduction leads to a rapid and sometimes catastrophic drop in accuracy. This threshold is governed by the information capacity of the network: a model must retain enough representational power to capture the complexity of the task. When compression exceeds this limit, the model can no longer approximate the target function with acceptable fidelity, and its predictions may become unreliable or erratic. The balance between compactness and performance is delicate, and identifying the precise boundary where accuracy begins to degrade sharply is a key challenge in neural network compression theory.

Robustness to Perturbations
expand arrow

Compressed models may react differently to input noise or adversarial examples compared to their uncompressed counterparts; understanding these differences is crucial for real-world deployment;

Stability Across Compression Levels
expand arrow

Some compression methods maintain stable performance over a range of compression ratios, while others exhibit abrupt drops in accuracy, highlighting the importance of method selection;

Sensitivity to Distribution Shifts
expand arrow

Compression can increase a model's sensitivity to changes in input data distribution, making robust evaluation essential;

Role of Redundancy
expand arrow

Redundant parameters often act as a buffer against perturbations; excessive compression removes this safety net, reducing robustness;

Trade-offs in Robustness and Efficiency

Achieving high efficiency through compression may come at the cost of decreased robustness, especially in safety-critical applications.

Note
Definition

Failure modes in model compression refer to distinct patterns of degraded performance or instability that emerge when a neural network is compressed beyond its theoretical limits. These can be mathematically characterized by abrupt increases in generalization error, loss of calibration, emergence of adversarial vulnerabilities, or instability in response to small input perturbations.
