Transaction strings as generated from credit cards data are short, telegraphic strings describing the vendor. Mapping them to transaction categories is a recurring problem in the banking industry. The technique described in this patent creates signatures using subsequences of characters from the transaction strings and then further conflates them using a deep autoencoder.
Using this method, it is possible to train a system to recognize that that transaction signatures with the words 'CAFE' are more likely related to the category 'Food&Beverages'.
