Possible typos in chapters 6, 7 and 9

[fayolle]

Some possible typos spotted while reading chapters 6 to 9:

• trees.html, section 6.4.5 "In Figure ," -> "In Figure (6.6)," http://www.mlfactor.com/trees.html#boosted-trees-extreme-gradient-boosting

• NN.html

  • Section 7.3.3: \delta_j instead of \delta_k in the expression of O
  • In 7.4.2 (second to last paragraph): “ validation accuracy (“val_acc”; one alternative is “val_loss”).” -> It is the opposite in the code.
  • In the "solutions-to-exercises.html" chapter, it seems that the numbering for the solutions is off by one. For example, the solution to the neural network exercise (chapter 7) is listed in "Chapter 8: the autoencoder model".

• bayes.html

  • In 9.2 "generator is symmetric (p(x|y) = (y|x))" -> p(x|y) = p(y|x)?
  • In 9.5 "The performance seems reasonable but is by no means not impressive." -> "is by no means impressive"?

Thank you again for your very thorough reading. I thus have added you in the acknowledgments :) And the book is now updated.
