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: “ The hyperparameter optimization methods in the scikit-learn Python library assume good performance scores are negative values close to zero.”

A block of code is set as follows:

import pandas as pd, numpy as np
from collections import Counter
import matplotlib.pyplot as plt

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

prediction = one_class_svm.predict(X_test)
prediction = [1 if i == -1 else 0 for i in prediction] #outliers denoted by 1, inliers by 0
print(classification_report(y_test, prediction))
