Abstract: A neural model for simulating a scorecard comprises a neural network for transforming one or more inputs into an output. Each input of the neural model has a squashing function applied thereto for simulating a bin of the simulated scorecard. The squashing function includes a control variable for controlling the steepness of the response to the squashing function's input so that during training of the neural model the steepness can be controlled. The output of the neural model represents the score of the simulated scorecard. The neural network is trained to behave like a scorecard by providing plurality of example values to the inputs of the neural network. Each output score produced is compared to an expected score to produce an error value. Each error value is back-propagated to adjust the neural network transformation to reduce the error value. The steepness of each squashing function is controlled using the respective control variable to affect the response of each squashing function.

Abstract: A method for analyzing data streams comprises receiving a data stream, conducting a first analysis of the data stream for a possible target activity, and if a possible target activity is indicated generating a first alert. If the first alert is generated, a second analysis for the possible target activity is conducted to determine whether the target activity is indicated in the data stream with a high degree of certainty. If a possible target activity is indicated by the second analysis, a second alert is generated and provided to an external system for action.

Abstract: A neural network comprises trained interconnected neurons. The neural network is configured to constrain the relationship between one or more inputs and one or more outputs of the neural network so the relationships between them are consistent with expectations of the relationships; and/or the neural network is trained by creating a set of data comprising input data and associated outputs that represent archetypal results and providing real exemplary input data and associated output data and the created data to neural network. The real exemplary output data and the created associated output data is compared to the actual output of the neural network, which is adjusted to create a best fit to the real exemplary data and the created data.
