Certain aspects of the present disclosure provide techniques for detecting data entry errors. A method generally includes receiving a string value as user input for a data field, selecting a plurality of reference values previously entered into the data field within a time period, processing, with an embedding model configured to classify an input string value as a valid or invalid entry, the string value and the reference values and thereby generating a first vector as output, computing one or more statistics for the reference values and the string value, creating a second vector based on the one or more statistics, generating a concatenated vector by concatenating the first vector and the second vector, processing, with a classifier model configured to classify the string value as valid or invalid, the concatenated vector and thereby generating a classification output, and taking action based on the classification output.

Deep learning based context embedding approach for detecting data entry errors

Certain aspects of the present disclosure provide techniques for detecting data errors. A method generally includes receiving a new value as user input for a data field, generating histogram-based approximations of kernel density estimates generated based on valid data and invalid data associated with the data field, determining a likelihood that the new value is a valid value and a likelihood that the new value is an invalid value, computing a likelihood ratio test statistic based on a ratio of the likelihoods, and classifying the new value as valid or invalid based on comparing the likelihood ratio test statistic to a likelihood ratio test threshold.
