Extended Data Fig. 5. Numerical evaluation of ACCEL with different pixel sizes, diffractive distances in OAC, and various exposure power.
a,b, Testing accuracies of ACCEL with different pixel sizes and diffractive distances on the MNIST dataset. Scale bar, 200 μm. The neuron number of OAC for the pixel sizes of 3 µm, 6 µm, 9.2 µm, and 12 µm are 500 × 500, 250 × 250, 164 × 164, and 126 × 126, respectively. c,d, The testing accuracy of ACCEL and digital NN under different exposure powers on MNIST and time-lapse tasks. ACCEL and digital NNs are trained under the exposure power of 3.38 fJ per µm2 per frame in (c) and 1.17 fJ per µm2 per frame in (d) (detailed network structures in Supplementary Table 1). We set the pixel size of OAC as 3 µm and the diffraction distance as 3 mm here.
