However, their high compute, memory, and power requirements make using them in low resources domains challenging. For this reason, neural networks are often compressed before deployment. Existing compression techniques tend to degrade the network accuracy. We propose Counter-Example Guided Neural Network Compression Refinement (CEG4N). This technique combines search-based quantization and equivalence verification: the former minimizes the computational requirements, while the latter guarantees that the network’s output does not change after compression. We evaluate CEG4N on a diverse set of benchmarks that include large and small networks. Our technique successfully compressed 80% of the networks in our evaluation while producing models with up to 72% better accuracy than state-of-the-art techniques.
