Quantization breaks memory in recurrent neural networks, researchers find

By PulseAugur Editorial · [2 sources] ·

A new research paper identifies a critical issue in low-precision recurrent neural networks, termed "recurrent-state write-back." This problem occurs when quantized states are stored and reused, leading to suppressed small updates that can freeze the network's memory. The study demonstrates that this phenomenon can drastically increase estimation errors, by up to 70x and 300x for specific parameters in a fluorescence lifetime imaging task. Researchers found that simple techniques like error feedback or residual memory can restore accuracy without retraining, and that compatibility with the state-storage interface is more crucial than bit-width alone.

    When Quantization Breaks Memory: Recurrent-State Write-Back in Low-Precision Temporal Inference

    arXiv:2609.04490v1 Announce Type: new Abstract: Quantization is widely used to reduce the computational and memory demands of neural-network inference. In recurrent networks, however, the quantized state is stored and returned at the next time step, so the rule used to store that…

    When Quantization Breaks Memory: Recurrent-State Write-Back in Low-Precision Temporal Inference

    Quantized recurrent inference suffers from state write-back rules that suppress small updates, but error feedback and residual memory restore accuracy without retraining across GRU and LSTM architectures.
