In the context of building a scalable and efficient data pipeline for a machine learning project, which of the following practices are essential to ensure high data quality throughout the pipeline? Choose two correct options.
Explanation:
Ensuring high data quality in a machine learning data pipeline involves several critical practices. Implementing comprehensive data validation and cleansing procedures at each stage (B) is essential to identify and rectify errors, ensuring the accuracy and consistency of data. Additionally, incorporating both batch and streaming data processing with tailored validation mechanisms for each (E) allows for flexibility and scalability in handling diverse data sources while maintaining quality. Batch processing alone (A) may not suffice for real-time data needs, and omitting data validation (C) or minimizing transformation steps without regard for data quality (D) can lead to significant issues downstream, affecting model performance and reliability.
