Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Since it’s possible to provide a base estimator to BaggingClassifier, let’s use DecisionTreeClassifier with the maximum depth of the trees being 6.”

A block of code is set as follows:

from collections import Counter X, y = make_data(sep=2)print(y.value_counts()) sns.scatterplot(data=X, x="feature_1", y="feature_2")plt.title('Separation: {}'.format(separation))plt.show()

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “True Negative Rate (TNR): TNR measures the proportion of actual negatives that are correctly identified as such.”
