Post-training Model Quantization Using GANs for Synthetic Data Generation

1 code implementation10 May 2023 Athanasios Masouris, Mansi Sharma, Adrian Boguszewski, Alexander Kozlov, Zhuo Wu, Raymond Lo

In this study, we investigate the use of synthetic data as a substitute for the calibration with real data for the quantization method.

Post-training deep neural network pruning via layer-wise calibration

no code implementations30 Apr 2021 Ivan Lazarevich, Alexander Kozlov, Nikita Malinin

We present a post-training weight pruning method for deep neural networks that achieves accuracy levels tolerable for the production setting and that is sufficiently fast to be run on commodity hardware such as desktop CPUs or edge devices.
