SYSTEMS AND METHODS FOR GENERATING A MACHINE LEARNING MODEL FOR RISK DETERMINATION

Methods and systems are presented for configuring a risk assessment engine to predict a risk of a user based on a topic classification across a set of unknown topics generated by a topic model. A risk determination system obtains a plurality of transactions previously conducted by a user. The risk determination system generates a risk document comprising a sequence of words that describe the plurality of transactions. A topic model is used to determine a topic classification for the user based on the sequence of words. The topic model comprises a natural language processor configured to classify the risk document to one or more topics based on the words within the risk document. The risk determination system configures the risk assessment engine to accept the topic classification as input value(s) for predicting a risk associated with the user.
