Scaling Data in Ticket Sales Prediction: The Benefits and Challenges of Min-Max Scaler and StandardScaler
Understanding the Problem and Scaler Selection When working with data that has varying scales, it’s essential to consider how scaling affects model performance. Scaling is a technique used to normalize data by transforming values into a common range, typically between 0 and 1 or -1 and 1. This helps prevent features with large ranges from dominating the model.
The Min-Max Scaler is one of the most commonly used scalers in Python’s scikit-learn library.
