Abstract: Extending the tempotron to conductance-based voltage kinetics, we show that this model can subserve time-warp invariant processing of afferent spike patterns. Furthermore, we show that the conductance-based tempotron can learn to balance excitation and inhibition to match its integration time constant to the temporal scale of a given processing task. These mechanisms enable already small populations of model neurons to match the performance of state-of-the-art speech recognition systems on isolated word recognition tasks. | |
