Abstract: In various examples, query-based evaluation of error patterns in annotated training data for machine learning systems and applications is provided. An error pattern evaluator may include an error pattern extraction function and an error pattern search algorithm. An annotated validation sample associated with an inaccurate prediction from a machine learning model may be analyzed to extract an error pattern.

An error pattern search algorithm may use the error pattern derived from the inaccurate prediction as a query to search the dataset to identify each occurrence of samples having an error pattern similar to the query error pattern. The set of annotated training data may be corrected based on the search results.
