Chapter 8: Batch gradient descent. Wrong alpha value

[cesarab]

In Chapter 8, the value of alpha in the dropout example is 0.005. In the batch gradient descent example, the text says that alpha is 20 times larger than before. 0.005 * 20 = 0.1

However, the value of alpha in the code example is 0.001.

I think it should be 0.1.
