plot_decision_boundary(lambda x: clf.predict(x)) plt.title("Logistic Regression") 可以看到,逻辑回归使用一条直线尽可能好的分割这个二分类问题,但是由于原先数据本就不是线性可分的,因此效果并不好。 1.4 - Training a Neural Network 现在来构建一个有一个输入层一个隐藏层和一个输出层的简单三层神经网络...

Transformer block 将前一章中的causal multi-head attention module 与linear layers、我们在前面部分实现的 feed forward neural network结合起来。此外,Transformer块还使用了dropout和shortcut connection。 from previous_chapters import MultiHeadAttention class TransformerBlock(nn.Module): def __init__(self, cfg...

There is some density above 500 watts but this has been cropped from this plot to allow us to see detail in the range between 0 and 500 watts. close to the value of 9.97 kWh per day reported in DECC's Household Electricity Survey19 (which surveyed 251 houses in the UK), hence we ...
