description | This paper introduces an event-driven feedforward
categorization system, which takes data from a temporal contrast
address event representation (AER) sensor. The proposed system
extracts bio-inspired cortex-like features and discriminates different
patterns using an AER based tempotron classifier (a network
of Leaky Integrate-and-Fire spiking neurons). One of the system’s
most appealing characteristics is its event-driven processing,
with both input and features taking the form of address events
(spikes). The system was evaluated on an AER posture dataset
and compared to two recently developed bio-inspired models.
Experimental results have shown that it consumes much less
simulation time while still maintaining comparable performance.
In addition, experiments on the Mixed National Institute of Standards
and Technology (MNIST) image dataset have demonstrated
that the proposed system can work not only on raw AER data
but also on images (with a preprocessing step to convert images
into AER events) and that it can maintain competitive accuracy
even when noise is added. The system was further evaluated on
the MNIST-DVS dataset (in which data is recorded using an AER
dynamic vision sensor), with testing accuracy of 88.14%. |
