The Impact of Data Quality in Predictive Analytics

High-quality data is necessary to train machine learning models effectively, enabling them to recognize patterns, make accurate predictions, and provide actionable insights. This is particularly important as machine learning becomes increasingly integral to industries like retail, healthcare, and marketing.
For example, in customer segmentation, machine learning models trained on high-quality data can help businesses better understand their customer base and personalize marketing efforts.
