Researchers have developed a new method called SPARC to improve the inference accuracy of photonic neural network accelerators. This approach addresses limitations caused by low-bit quantization and analog photonic noise inherent in these systems. SPARC achieves this by identifying groups of similar activation vectors and computing a representative vector's inner product digitally with high precision, while offloading the remaining computations to the photonic accelerator. This technique preserves the existing photonic computation pipeline and has demonstrated improved accuracy across various deep neural network models. AI
