The leakage everyone keeps writing into their portfolio projects

1. 1Identify potential leakage sources in your dataset
2. 2Apply techniques to prevent data leakage, such as data splitting and feature engineering
3. 3Test and validate your models using techniques like cross-validation
4. 4Evaluate and compare the performance of your models with and without leakage
5. 5Refactor your code to ensure data leakage is avoided

Data scientists and analysts can benefit from this knowledge to improve the quality and reliability of their portfolio projects, and make them more attractive to potential employers

💡 Data leakage can significantly impact the performance and reliability of machine learning models, and avoiding it is crucial for building robust and generalizable models
