Abstract: A method and a system are disclosed for initializing a pre-trained neural network, the method comprising obtaining a pre-trained neural network having an output layer, amending the output layer of the pre-trained neural network, wherein the amending comprises updating each weight of the output layer according to a function that maximizes the entropy of the output classes probability, wherein the function depends on a parameter controlling a proportion of error of the output classes probability such as it decreases the variance of the output classes probability, and providing the initialized pre-trained neural network.

Abstract: Methods and systems for access control systems such as firewalls. The system detects conflicts between two access control rules by finding all common variables between the two rules and determining if there are values for all the common variables that simultaneously satisfy both rules. If there are such values, and if the end result of the two rules are different, then the two rules are in conflict with one another.

Abstract: Methods and devices for assessing a user's skill level in a field of expertise based on game play data generated by that user. In one embodiment, a user plays a game which simulates an auditing interview. The user selects predefined questions to ask a computer controlled interviewee and a game log of the questions asked, reactions to the questions, and other data is created. The game log is then sent to an assessment system with multiple assessment modules. Each assessment module analyzes the game play data for specific patterns in the questions being asked. Patterns such as the sequencing of questions, the type and frequency of questions asked, and whether specific questions are asked may then be tracked and assessed. Based on the results of the various assessment analyses, a final metric indicative of the user's skill level is calculated. Advice and tips for the user to increase his skill level may also be provided based on what patterns were found in the game play data.
