Approximate Multiplier Induced Error Propagation in Deep Neural Networks
NeutralArtificial Intelligence
- A new analytical framework has been introduced to characterize the error propagation induced by Approximate Multipliers (AxMs) in Deep Neural Networks (DNNs). This framework connects the statistical error moments of AxMs to the distortion in General Matrix Multiplication (GEMM), revealing that the multiplier mean error predominantly governs the distortion observed in DNN accuracy, particularly when evaluated on ImageNet scale networks.
- This development is significant as it provides a mathematical basis for understanding how AxMs can reduce energy consumption in hardware accelerators without severely impacting the accuracy of DNNs. By quantifying the relationship between AxM errors and DNN performance, this research could guide future designs of energy-efficient neural network architectures.
- The findings highlight ongoing challenges in optimizing DNNs, particularly regarding the balance between computational efficiency and accuracy. As the demand for more efficient AI models grows, innovations like mixed-precision quantization and dynamic parameter optimization are increasingly relevant. These advancements aim to enhance DNN performance while addressing the complexities introduced by various error propagation mechanisms.
