In the context of preparing data for a machine learning model, feature engineering plays a pivotal role. Consider a scenario where you are working on a predictive maintenance project for manufacturing equipment. The dataset includes raw sensor readings, equipment IDs, timestamps, and maintenance records. The goal is to predict equipment failure before it occurs to minimize downtime. Given the complexity of the data and the critical nature of the predictions, how does feature engineering contribute to framing this machine learning problem? (Choose one correct option)
A
It directly evaluates the model's performance by comparing predicted failures to actual maintenance records.
B
It defines the project's objectives, such as reducing equipment downtime and predicting failures accurately.
C
It transforms the raw sensor readings and maintenance records into meaningful features that the model can use to learn patterns indicative of impending failures.
D
It determines the size of the dataset by deciding how many sensor readings to include in the model.
