Backpropagation-through-time (BPTT) is the canonical temporal-analogue to backprop used to assign credit in recurrent neural networks in machine learning, but there's even less conviction about whether BPTT has anything to do with the brain. Even in machine learning the use of BPTT in classic ...
During learning, the brain modifies synapses to improve behaviour. In the cortex, synapses are embedded within multilayered networks, making it difficult to determine the effect of an individual synaptic modification on the behaviour of the system. The b

Besides that, we also proposed the new architecture and the learning algorithm of recurrent neural network such as Backpropagation Through Time (BPTT), which well-suited. We also re-train for the output before we analyze the result. The purpose of this training is to produce the best result....

The SNN is NOT an RNN, despite it evolves through time too. For this SNN to be an RNN, I believe it would require some more connections such as from the outputs back into the inputs. In fact, RNNs are defined as a function of some inputs and of many neurons at the previou...
way, they are merely and expression of my curiosity and are meant to be looked at strictly from a programmer's "How do I implement this" point of view rather than from a mathematician's or from the point of view of someone who is trying to replicate the way the brain actually ...
The proposed ABPN-based seizure detection system is validated using Physionet EEG dataset with matlab simulation, and the effectiveness of proposed seizure system is confirmed through simulation results. As compared with Deep Convolutional Neural Network (CNN) and Support Vector Machine鈥揚article Swarm...
The brain processes information through multiple layers of neurons. This deep architecture is representationally powerful, but complicates learning because it is difficult to identify the responsible neurons when a mistake is made. In machine learning, the backpropagation algorithm assigns blame by multip...
we explicitly provide the dynamical system that implements backpropagation through time and show that it represents an adjoint spiking network which transmits errors at spike times, allowing for an event-based computation of the gradient. In addition, we also consider voltage-dependent loss functions ...
