According to The AI Playbook, what is the primary purpose of feature engineering in machine learning systems such as fraud detection models?

In logistic regression, the model generates a score by applying weights to each input, summing the weighted inputs, and then applying a nonlinear transformation to produce an output.

In machine learning, signal refers to meaningful patterns that help predict the target outcome, while noise consists of irrelevant, erroneous, or random variation in the data that can degrade model performance if not addressed.

Which of the following best represents a properly framed BizML problem statement?

For effective fraud detection models, data must be long (many transactions), wide (many attributes describing each transaction), and labeled, because machine learning models require representative examples, explanatory variables, and known outcomes to learn accurately.
