BPTT begins by unfolding a recurrent neural network in time. The unfolded network contains k {\displaystyle k} inputs and outputs, but every copy of the network shares the same parameters. Then, the backpropagation algorithm is used to find the gradient of the loss function with respect to all the network parameters.
The standard method for training RNN by gradient descent is the "backpropagation through time" (BPTT) algorithm, which is a special case of the general algorithm of backpropagation. A more computationally expensive online variant is called "Real-Time Recurrent Learning" or RTRL, [ 78 ] [ 79 ] which is an instance of automatic differentiation in ...
Pronounced "A-star". A graph traversal and pathfinding algorithm which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. abductive logic programming (ALP) A high-level knowledge-representation framework that can be used to solve problems declaratively based on abductive reasoning. It extends normal logic programming by allowing some ...
12-tone equal temperament chromatic scale on C, one full octave ascending, notated only with sharps. Play ascending and descending ⓘ. 12 equal temperament (12-ET) [a] is the musical system that divides the octave into 12 parts, all of which are equally tempered (equally spaced) on a logarithmic scale, with a ratio equal to the 12th root of 2 (≈ 1.05946).

The standard method is called "backpropagation through time" or BPTT, a generalization of back-propagation for feedforward networks. [45] [46] A more computationally expensive online variant is called "Real-Time Recurrent Learning" or RTRL. [47] [48] Unlike BPTT this algorithm is local in time but not local in space.
Training using synthetic gradients performs considerably better than Backpropagation through time (BPTT). [11] Robustness can be improved with use of layer normalization and Bypass Dropout as regularization. [12]
