Our proposed pipeline, termed Deep k -Means, has well-aligned goals between re-training and compression stages. We further propose an improved set of metrics to estimate energy consumption of CNN hardware implementations, whose estimation results are verified to be consistent with previously proposed energy estimation tool extrapolated from actual hardware measurements. We have evaluated Deep k -Means in compressing several CNN models in terms of both compression ratio and energy consumption reduction, observing promising results without incurring accuracy loss.
