Firstly, general function approximation abilities of neural networks are briefly introduced. Then, two classes of commonly used neural networks, linearly parameterized networks and non-linearly parametrized net
Deciphering the relationship between a gene and its genomic context is fundamental to understanding and engineering biological systems. Machine learning has shown promise in learning latent relationships underlying the sequence-structure-function paradig
Some simple computing hardware might not support the exponential function directly, and software implementations can be slow. The Elliot sigmoidelliotsigfunction performs the same role as the symmetric sigmoidtansigfunction, but avoids the exponential function. Here is a plot of the Elliot sigmoid...
Bayesian regularization has been implemented in the function trainbr. The following code shows how you can train a 1-20-1 network using this function to approximate the noisy sine wave shown in the figure in Improve Shallow Neural Network Generalization and Avoid Overfitting. (Data division is can...
我们将看到,在相同的条件下,训练期间 ANN 的行为是由相关核来描述的,我们将其称为神经正切网络(neural tangent network)。 1.1 贡献 我们对 ANN 的网络函数 f_\theta 进行了研究,其将输入向量映射到输出向量,其中 \theta 表示ANN 的参数向量。在隐藏层宽度趋于无穷大的条件下,初始化时的网络函数 f_\theta ...
