Not sure of page number, since viewing online and don't see an obvious way to determine that, but in the section:
Chapter 5 - Writing a Mushroom Classifier - Coding and testing design :
in the description of classes found below the line:
"From here we define the following classes (see Figure 5-6):"
The class MushroomForest is incorrectly spelled MushroomForrest (with extra 'r' in Forest)
Note from the Author or Editor:
Got it, fixed it in the next pressing. Thanks for submitting the errata :) |

Top of the page |
The triangle inequality as listed on the page has a typo. On the page it's listed as
||x|| + ||y|| <= ||x|| + ||y||
This isn't right as the two sides of the equation are the same. It should be
||x + y|| <= ||x|| + ||y||

(Stars above indicate change)
Enjoying the book so far otherwise!
Note from the Author or Editor:
I have added the change to Atlas. And should be good to go on next release. |

Page 38
12th line of text |
the line states:
self.df = self.df[['lat', 'long', 'SqFtLot']
There is a missing close bracket. The line should read:
self.df = self.df[['lat', 'long', 'SqFtLot']]

6th mathematical expression |
error line: total = 6.0
This line should be corrected as
total = 5.0 (because len (a | b) = 5 )
in spite of correcting does not affect the result of p_a_given_b calculation, as the variable 'total' appears both of the upper and lower term of it's calculation.
Note from the Author or Editor:
Yup this is definitely an issue and should be changed. |

"Mathemeticians" is spelled incorrectly. Should be "Mathematicians".

Hello, I am trying to work through the neural network project source example of chapter 8. However, I am not able to get very far. When I attempt to restore the Python project dependencies as such:
pip3 install -r requirements35.txt
I encounter the following error message:
Could not find a version that satisfies the requirement climate==0.4.6 (from -r requirements35.txt (line 7)) (from versions: )
No matching distribution found for climate==0.4.6 (from -r requirements35.txt (line 7))
After doing some basic investigation, I found that the Python module 'climate' is no longer available. The GitHub project has been removed. I purchased this book just a few months ago and would appreciate some technical guidance (as would other reasons, I imagine).
Note from the Author or Editor:
Hey there,
I have updated the github repository. Climate is actually not needed to run the examples. So please try again.
And thank you for submitting this errata :) |
