To
demonstrate the emulator, the generated neuron’s tuning curves and the
corresponding generated spikes are shown in Figure 7, B. A
SPICE-made spike was encapsulated in the emulator and iteratively
generated in Python following the desired tuning curve, specified by
OZ’s voltage signals described above. SPICE and emulator-generated
neuron tuning show high correspondence. Similar to Figure 3, D ,
we used our emulator to represent sinusoidal waves with 8 neurons
(Figure 7, C ). The results show a very high correlation with
the SPICE circuit simulation, thus demonstrating the accurate emulation
of the learning core. Weight modulations in both the SPICE simulation
and the emulator show comparable patterns. Similarly, high-dimensional
representation (Figure 4, C ) and transformation (Figure
5, B ) demonstrate the emulator’s accuracy (Figure 7, D-E ).
