چکیده
and ei(t) is the output error, xi(t) represent the activations and δi(t) are the backpropagated errors. The system described by Eq. 1 and Eq. 2 constitute the backpropagation through time (BPTT) algorithm. Note that the backpropagation system (Eq. 2) should be run from t=T backwards to t=1. We define the boundary conditions δi(T+1)=0. We will assume that the instantaneous error signal ei(t) is zero for t<T. The backpropagation system (Eq.2) reduces in this case to

Using CMAC for Mobile Robot Motion Control
Cerebellar Model Articulation Controller (CMAC) has some attractive features: fast learning capability and the possibility of efficient digital hardware implementation. These features makes it a good choice for different control applications, like the one presented in this paper. The problem is to navigate a mobile robot (e.g a car) from an initial state to a fixed goal state. The approach appl...
متن کاملExtension of Backpropagation through Time for Segmented-memory Recurrent Neural Networks
We introduce an extended Backpropagation Through Time (eBPTT) learning algorithm for SegmentedMemory Recurrent Neural Networks. The algorithm was compared to an extension of the Real-Time Recurrent Learning algorithm (eRTRL) for these kind of networks. Using the information latching problem as benchmark task, the algorithms’ ability to cope with the learning of long-term dependencies was tested...
متن کاملMemory-Efficient Backpropagation Through Time
We propose a novel approach to reduce memory consumption of the backpropagation through time (BPTT) algorithm when training recurrent neural networks (RNNs). Our approach uses dynamic programming to balance a trade-off between caching of intermediate results and recomputation. The algorithm is capable of tightly fitting within almost any user-set memory budget while finding an optimal execution...
متن کاملMemory-based control with recurrent neural networks
Partially observed control problems are a challenging aspect of reinforcement learning. We extend two related, model-free algorithms for continuous control – deterministic policy gradient and stochastic value gradient – to solve partially observed domains using recurrent neural networks trained with backpropagation through time. We demonstrate that this approach, coupled with long-short term me...
متن کاملA Fixed Size Storage O(n3) Time Complexity Learning Algorithm for Fully Recurrent Continually Running Networks
There are two basic methods for performing steepest descent in fully recurrent networks with n noninput units and m = O(n) input units. Backpropagation through time (BPTT) [e.g., Williams and Peng (1990)l requires potentially unlimited storage in proportion to the length of the longest training sequence but needs only O(n’) computations per time step. BPTT is the method of choice if training se...
