1). This leads to the weight transport problem (a), which has been solved by using symmetric learning rules to maintain weight symmetry50,52,53 or with the Kolen-Pollack algorithm53,54,55, which leads to symmetric weights automatically. It has also been found that weights do not have to ...

The multistage optimal control problem can be solved in various ways, as, e.g., by the application of dynamic programming. Within the backpropagation framework, weights are tuned layer-by-layer as well as step-by-step to minimize the learning error. Meanwhile, in the new algorithm for each...
The BP neural network algorithm has the ability of arbitrary complex pattern classification and excellent multidimensional function mapping, which can solve other problems such as XOR, which cannot be solved by simple perceptrons. Structurally, the BP network has an input layer, a hidden layer, and...
The problem of extraction of crisp logical rules from neuralnnetworks trained with a backpropagation algorithm is solved by smoothntransformation of these networks into simpler networks performingnlogical functions. Two constraints are included in the cost function: anregularization term inducing weight ...
For example, Gilra and Gerstner50 developed a spiking model in which feedback about the error on the output directly affects the activity of hidden neurons before plasticity takes place. Haider et al.51 developed a faster inference algorithm for energy-based models that computes a value to ...
Neural Networks in Python Coursera: Machine Learning wiki - Backpropagation The Backpropagation AlgorithmCommunicationsHello,I'm a novice programmer in Python and new to Deep Learning. Was reading your example of the XOR with one hidden layer and backpropagation seen in:https://www.bogotobogo....
The cloud genetic algorithm is introduced in the experiment to optimize the BP neural network. The purpose is to optimize and improve the initial weights and thresholds of the BP neural network. Simultaneously, the improvement and optimization of the overall topological structure shape can be ...
enabling the global evolution to continue. The local and global evolution efficiency of the hybrid search mechanism is considerably higher than that of simple search among ordinary individuals. For example, Arab [21] proposed an adaptive local search memetic algorithm to enhance the precision and conv...
A fundamental question in neuroscience is how upstream synapses (for example, the synapses betweenxiandhjinFig. 1a) might be adjusted on the basis of downstream errors (for example,einFig. 1a). The learning algorithm backprop computes gradients of the performance, that is, the loss, for each...
