Claim 19:
20. An apparatus comprising:
a processing system including at least one processor; and
a computer-readable medium storing instructions which, when executed by the processing system, cause the processing system to perform operations, the operations comprising:
applying a binary classifier to detect whether a first data pattern of a first data source, from among a plurality of data sources associated with a performance indicator of a communication network, is consistent with prior data patterns of the first data source that are labeled as correct data patterns from one or more time periods prior to the first data pattern, wherein the binary classifier is trained based upon the prior data patterns, wherein the first data source comprises an active data source;
determining, via the binary classifier, that the first data pattern is not consistent with the prior data patterns of the first data source that are labeled as correct data patterns;
applying a clustering model to a first input data set comprising the first data pattern and a plurality of invalid data patterns of the first data source to obtain a first plurality of clusters;
verifying that the first data pattern is an invalid data pattern for the first data source when the first plurality of clusters is the same as a second plurality of clusters, the second plurality of clusters generated by applying the clustering model to a second input data set comprising the plurality of invalid data patterns; and
replacing the first data source with a replacement data source as an active data source from among the plurality of data sources in response to the verifying that the first data pattern is an invalid data pattern for the first data source.
