Table data verification is often boring and unavoidable.If the following form has only two input boxes and a confirmation button, what do we need to do normally?
1. If a non-numeric string is entered in the age input box and the input box loses focus, the following error message should be immediately prompted.
2. If the content of the error message changes, you may need to modify the overall uidesign (for example, it is displayed below the input box)
The following small series to take an example to explain in detail:
This example requires that the language score above 120 points be highlighted in the red circle. Screen operation steps:
The first step: open the results table → Choose the language results → Click the Data button on the menu bar → Select effectivity.

Normally to perform supervised learning you need both types of data sets:
In one dataset (your ' gold standard ') you had the input data together with correct/expected output, this dataset is usual Ly duly prepared either by humans or by collecting some the data in semi-automated. But it's important, and the expected output for every
