What does feature engineering primarily aim to enhance in a machine learning model?

Feature engineering primarily aims to enhance estimation accuracy in a machine learning model. This process involves selecting, transforming, and creating features from raw data to improve the model's ability to learn and make predictions. By providing the algorithm with more relevant, high-quality input features, the model can better capture the underlying patterns in the data.

When features are carefully crafted, they can significantly boost the predictive power of models, leading to improved accuracy in the outcomes generated. For instance, creating interaction terms, normalizing data, or encoding categorical variables appropriately can make it easier for the model to identify relationships within the data.

While computation speed, data storage capacity, and model interpretability are important aspects of machine learning, they are secondary considerations in the context of feature engineering. The primary goal is always to derive features that will enable the model to make more accurate predictions. If the input features do not convey the necessary information or the relationships within the data are poorly represented, the model will likely underperform, regardless of other factors.
