feature-engineering

Vocabulary Word

Definition

Feature Engineering is important in data science. It involves transforming raw data into a format that can be easily understood by algorithms. This process can make machine learning models more accurate and efficient.

Examples in Different Contexts

In data science, 'feature engineering' involves creating new input variables from existing data to improve model performance. A data scientist might say, 'Through feature engineering, we transformed raw data into meaningful features that significantly enhanced our predictive model's accuracy.'

Practice Scenarios

Data Science

Scenario:

Making sense of this enormous dataset isn't straightforward. Discovering meaningful patterns might need innovative use of our data.

Response:

Feature engineering technique could be a game-changer here, enabling us to unlock valuable insights from this dataset.

Software

Scenario:

We want to predict system performance under heavy loads. The data we've collected needs some tuning to be more intelligible for the predictive model.

Response:

Let's do some feature engineering on our collected data. It will make it more suitable for predicting system performance.
