QBitOpt: Fast and Accurate Bitwidth Reallocation during Training

no code implementations10 Jul 2023 Jorn Peters, Marios Fournarakis, Markus Nagel, Mart van Baalen, Tijmen Blankevoort

By combining fast-to-compute sensitivities with efficient solvers during QAT, QBitOpt can produce mixed-precision networks with high task performance guaranteed to satisfy strict resource constraints.

Quantization Robust Federated Learning for Efficient Inference on Heterogeneous Devices

no code implementations22 Jun 2022 Kartik Gupta, Marios Fournarakis, Matthias Reisser, Christos Louizos, Markus Nagel

We perform extensive experiments on standard FL benchmarks to evaluate our proposed FedAvg variants for quantization robustness and provide a convergence analysis for our Quantization-Aware variants in FL.

Overcoming Oscillations in Quantization-Aware Training

1 code implementation21 Mar 2022 Markus Nagel, Marios Fournarakis, Yelysei Bondarenko, Tijmen Blankevoort

These effects are particularly pronounced in low-bit ($\leq$ 4-bits) quantization of efficient networks with depth-wise separable layers, such as MobileNets and EfficientNets.

A White Paper on Neural Network Quantization

no code implementations15 Jun 2021 Markus Nagel, Marios Fournarakis, Rana Ali Amjad, Yelysei Bondarenko, Mart van Baalen, Tijmen Blankevoort

Neural network quantization is one of the most effective ways of achieving these savings but the additional noise it induces can lead to accuracy degradation.
