Extended Data Fig. 4 | Experimental accuracy of parallel memristor
convolvers after hybrid training, and simulated training efficiency of
different combinations of tuning layers. a, The error rate on the entire
training set after hybrid training drops substantially compared with that
achieved after weight transfer for any individual convolver group. The error
rates with respect to the G1, G2 and G3 groups decrease from 4.82%, 6.43% and
5.85% to 2.89%, 4.22% and 3.40%, respectively, after hybrid training. b,
Simulation results for all combinations of tuning weights for different layers
using hybrid training and the five-layer CNN.
