Planar data classification with one hidden layer 你会学习到如何: 用单隐层实现一个二分类神经网络 使用一个非线性激励函数,如 tanh 计算交叉熵的损失值 实现前向传播和后向传播 1 - Packages(导入包) 需要导入的包: numpy:Pyt
We can also use the eye() function to perform one-hot encoding on arrays. It returns a 2-Dimensional with 1 at the main diagonal and 0 elsewhere by default. We can use this method and specify the locations we want 1s to be, as shown below.import...

Since we have taken great care to make Numpy.NET as similar to NumPy itself, you can, for the most part, rely on the officialNumPy manual. Creating multi-dimensional NDarrays from C# arrays Creating anNDarrayfrom data is easy. Just pass the C# array intonp.array(...). You can pass ...
