How to Evaluate Time Series Models with Walk-Forward Validation
📰 Medium · Data Science
Learn to evaluate time series models using walk-forward validation to avoid common mistakes in data splitting
Action Steps
- Split your time series data into training and testing sets using walk-forward validation
- Train a time series model on the training data
- Evaluate the model's performance on the testing data using metrics such as mean absolute error or mean squared error
- Compare the performance of different models using walk-forward validation
- Refine your model by adjusting hyperparameters and re-evaluating its performance
Who Needs to Know This
