| 520 | _ | _ | |a Learning and processing sequential data constitutes a universal form of computation performed by the brain. Understanding the underlying principles does not only shed light on brain function, but also guides the development of energy efficient neuromorphic computing architectures. In a previous study, we devised a spiking recurrent neural network, the spiking temporal memory (spiking TM) model, implementing this type of computation. It learns sequences in a continual, unsupervised manner by means of a local Hebbian synaptic plasticity mechanism. Context specific predictions of upcoming sequence elements are represented by dendritic action potentials. Upon successful learning, the network activity is characterized by a highly sparse and hence energy efficient code. To date, the sequence learning capabilities of the spiking TM model have only been demonstrated for relatively small sequence sets. Here, we systematically investigate the sequence learning capacity of the model by gradually increasing the sequence length and optimizing the plasticity (hyper-) parameters. We show that the spiking TM model at the scale of a few thousand neurons can successfully learn random sequences composed of several tens of elements,with the maximum sequence length exceeding the vocabulary size. After optimizing the plasticity parameters for a given sequence length, the model exhibits high prediction performance for a range of sequence lengths, without additional fine tuning.The learning duration (time to solution) scales supralinearly with the sequence length. Learning longer sequences is hence computationally demanding, and requires accelerated computing architectures. |
