Today, we are already living in the information age. The database we have is becoming more and more comprehensive. It is no longer just a little bit of poor data at hand, but includes a large amount or even all of the data related to these phenomena. We no longer need So worrying about the negative impact of a particular stronghold on the entire analysis. What we have to do is accept and benefit from this plethora of data, instead of eliminating all uncertainty at a high cost. The text is intended to emphasize:. ['All data information is inevitably uncertain.', 'A single data point has no significant negative impact on the overall analysis.', 'Big data speaks with probability, not stubbornly.', 'In the era of big data, we must learn to accept and identify complexity and confusion.']
