Abstract
Embodiments of the present disclosure provide method, device and computer storage medium for diagnosing and optimizing a data analysis system. The method disclosed herein comprises: obtaining information about an analysis engine in a data analysis system to be diagnosed and data to be diagnosed, the data to be diagnosed being associated with the analysis engine and comprising at least one of training data and prediction data for the analysis engine; determining a diagnosis engine corresponding to the analysis engine based on the received information; and providing a metric of uncertainty associated with at least one of the analysis engine and the data to be diagnosed by processing the data to be diagnosed with the diagnosis engine, the metric of uncertainty indicating a level of certainty for a prediction result obtained by processing the data to be diagnosed with the analysis engine. Based on this method, a diagnosis engine corresponding to an analysis engine can be used to determine an impact of a model or data to be diagnosed on accuracy of a prediction of an analysis engine of a data analysis system, thereby enabling a user to select a suitable data analysis model or to determine data to be diagnosed and to avoid possible defects.
