Robust Processing-In-Memory Neural Networks via Noise-Aware Normalization

Tsai, Li-Huang, Chang, Shih-Chieh, Chen, Yu-Ting et al.

Understand

Analog computing hardwares, such as Processing-in-memory (PIM) accelerators, have gradually received more attention for accelerating the neural network computations.

  • However, PIM accelerators often suffer from intrinsic noise in the physical components, making it challenging for neural network models to achieve the same performance as on the digital hardware.
  • Previous works in mitigating intrinsic noise assumed the knowledge of the noise model, and retraining the neural networks accordingly was required.
  • In this paper, we propose a noise-agnostic method to achieve robust neural network performance against any noise setting.
