Data frame analytics enable you to perform different analyses of your data and annotate it with the results. Essentially, as part of its output, data frame analytics appends the results of the analysis to the source data. By doing this, it provides additional insights into the data. The process leaves the source index intact, it creates a new index that contains a copy of the source data and the annotated data. You can slice and dice the data extended with the results as you normally do with any other data set.

You can evaluate the data frame analytics performance by using the evaluate data frame analytics API against a marked up data set. It helps you understand error distributions and identifies the points where the data frame analytics model performs well or less trustworthily.
