Listing 8.1
d_test = d[int((1-split)*len(d)):]

should be
d_test = d[int((split)*len(d)):]

Page 29, Paragraph 4 (Finally, each of these ...), Line 10

'to taker smarter actions' should be 'to take smarter actions'.

I'm not sure if this is an error, but figure 3.6 does not include the target, i.e., whether the passenger survived or not.

Awkward wording in 4.2.1
In 4.2.1, the author states "For example, you can analyze the accuracy per class (how many were predicted to survive but actually died or survived)."

All of the passengers died or survived ... unless this is some obscure reference to Schrodinger's cat ... so this sentence probably needs revising.
