Face-voice association towards multimodal-based authentication using modulated spike-time dependent learning
We propose a reward based learning to associate face and voice stimuli. In particular, we implement learning in a spiking neural network paradigm using modulated spike-time dependent plasticity (STDP).The face and voice stimuli are paired with a temporal delay, and the network is trained to associ...

Summary: | We propose a reward based learning to associate face and voice stimuli. In particular, we implement learning in a spiking neural network
paradigm using modulated spike-time dependent plasticity (STDP).The face and voice stimuli are paired with a temporal delay, and the network
is trained to associate the paired face-voice with a target response.The learning rule is dependent on a reward policy in which the network is given
a positive reward for a correct response to a face-voice stimulus pair, or the network receives a negative reward for an incorrect response. Despite a stochastic environment, the learning result of real images and sound indicates a
good performance with 77.33% accuracy.The result demonstrates that a machine can be trained to associate a pair of biometric inputs to a target response. |
