1. A method comprising:
- automatically generating a causal model corresponding to a user;
estimating a plurality of components of the causal model using event parameters of a first set of events undertaken by the user in an account of the user; and
predicting expected behavior of the user during a second set of events using the causal model.

Abstract
Systems and methods are provided for predicting expected behavior of a user in an account. The systems and methods automatically generate a causal model corresponding to a user. The systems and methods estimate a plurality of components of the causal model using event parameters of a first set of events undertaken by the user in an account of the user. The systems and methods predict expected behavior of the user during a second set of events using the causal model.

40. A method comprising:
-
receiving a plurality of observations corresponding to a first event, the first event including actions taken in an account during electronic access of the account; generating probabilistic relationships between the observations and derived parameters of an owner of the account; automatically generating an account model to include the probabilistic relationships; and estimating actions of the owner during a second event using the account model, wherein the second event follows the first event in time.

41. A method comprising:
-
automatically generating a causal model corresponding to a user, the generating comprising estimating a plurality of components of the causal model using event parameters of a previous event undertaken by the user in an account of the user; predicting expected behavior of the user during a next event in the account using the causal model, wherein predicting the expected behavior of the user includes generating predicted event parameters of the next event; receiving observed event parameters of the next event; and updating the causal model for use in a future event, the updating comprising regenerating the plurality of components based on a relationship between the expected event parameters and the observed event parameters.

- 42. A system comprising a processor executing at least one application, the application receiving event parameters of a first set of events undertaken by the user in an account of the user, the application automatically generating a causal model corresponding to a user by estimating a plurality of components of the causal model using the event parameters of the first set of events, the application using the causal model to output a prediction of expected behavior of the user during a second set of events.
