To this end, we propose a novel adaptive learning rate schedule for neural network training via SIGNSGD optimizer for the first time. In our method, based on the theoretical inspiration that the convergence rate
Can you show me where are they or Can i specify them in my network? Thank you so much! 댓글 수: 1 Katy2023년 7월 20일 Is there a solution for this? I'd also like to know how to change the learning rate for a shallow neural network. ...
they achieve the optimal parameters (biases and weights) for the given ANN. Determining the structure of the ANN is a prerequisite of this process. The number of processors (i.e., neurons) in the hidden layers is an important variable. In this work...
This section is concerned with presenting a neural formula that can predict thePu. All hybrid models used in this work had the same structure of the neural network (i.e., 6 × 5 × 1) as shown in Fig.9. The difference was their computational weights and biases that were tuned...
defadd_layer(inputs, in_size, out_size, activation_function=None): 接下来,我们开始定义weights和biases。 因为在生成初始参数时,随机变量(normal distribution)会比全部为0要好很多,所以我们这里的weights为一个in_size行,out_size列的随机变量矩阵。在机器学习中,biases的推荐值不为0,所以我们这里是在0向量...
[1] and assumes that the training of deep neural networks unfolds in two phases. During the first phase, the optimizer needs to pass through a high amount of saddle points fast. After that, the optimizer finds a local minimum at which it needs to converge slowly to its center. A high ...
The results indicate that neural network can be used as an efficient method in predicting customer churn, and telecommunication companies can use the proposed method for this aim. Coussement and De Bock [7] presented a comparison between single data mining methods and hybrid methods, which are ...
The effective extreme gradient boosting classification algorithm, which is used to classify the characteristics obtained by the convolutional layers, was used to substitute the fully connected layers of a standard convolution neural network in order to increase classification accuracy92. Furthermore, to ...
The fitness function value is a kind of important information in the search process, which can be more targeted according to the guidance of the fitness function value. Most existing meta-heuristic algorithms only use the fitness function value as an indicator to compare the current variables as ...
to at least the gradient with respect to the parameters of the child neural network, an update rule to generate an update to values of the parameters of the child neural network; andapplying the update to the values of the parameters of the child neural network,wherein the update rule has...
