Machine learning provides insights in reports from Power BI, and it allows you to quickly develop those insights by incorporating vast data volume into your reports.

Power BI aims to replace opinions and hunches with data-driven facts. That implies the data's insights must be accessible immediately, so that you may run a report when people still debate what it consists of, neither five minutes afterward when all have made their minds. Microsoft now employs machine learning for fine-tuning how data is accessible, even with massive data sets stored wherever they are.

If you have adequate data for making judgments with, you must consolidate and summarise it while maintaining dimensions of the original. For example, you could view total sales around all departments to obtain an overview, but split it by month or region to analyze patterns. According to Microsoft Analytics CTO Amir Netz, most Power BI customers want these queries in aggregate.

"They aren't interested in individual plane tickets or supermarket orders; they desire for data slicing and dicing at a higher level".

He emphasized that while aggregated searches must scan a large amount of data, the results are quite concise."If I query for monthly sales by geography, I can scan data rows in 250 billion; nevertheless, monthly sales by geography will only have the rows in 1,000 in it, despite the fact that there are 250 billion rows underneath. As a result, there is a considerable volume reduction".
