- Abstract
- We present a result on unsupewised
classification of extracellular neural signal with
low signal-to-noise ratio (SNR) usrng selforganizing
map {SUM). Instead of using simple
amplitude thresholding, energy operator is used
for the detection of neural spike to utilize both the
instantaneous amplitude and frequency
information. M e n applied to synthesized and real
experimental data with high background noise,
satisfactory clustering can be obtained. If
necessary, learnxng time can be significantly
reduced by using principal components of input
data as the input to the map.
