  • Publication number: 20190362228
    Abstract: A learning support device stores, as execution information, a set of an input value, an execution output value as an execution result and an expected output value, for a machine learning program. An arithmetic device generates an output value different from the expected output value as a teacher output value in accordance with a predetermined rule when the execution output value and the expected output value for a predetermined input value match each other, generates a loss function based on a difference between the teacher output value and the execution output value, generates a change value indicating a change in the loss function for each parameter in the neural network, calculates an influence degree of predetermined learning by calculating influence of an update value of the parameter obtained by the learning on the change value, and determines whether or not the update value is adopted based on the influence degree.

  • Publication number: 20190129620
    Abstract: A method is provided for reducing memory consumption by a rule engine. The method includes receiving attack trees, each having nodes and edges. Each node represents a security event and is associated with a detection rule for detecting an occurrence thereof. Each edge connects a respective node pair. The method includes assigning a watchpoint to each leaf node. The method includes moving the watchpoint assigned to any leaf node to a next upstream node, responsive to detecting an occurrence of the security event represented by the leaf node. The method includes erasing the watchpoint assigned to all downstream nodes relative to the next upstream node, responsive to the next upstream node being connected to a next downstream node using an edge having an “OR” join type. Only the rules for nodes currently having the watchpoint assigned are loaded into a memory device during runtime, while excluding rules for remaining nodes.

  • Publication number: 20190065755
    Abstract: A computer-implemented method, a computer program product, and a computer system for transformation of security information and event management (SIEM) rules and deploying the SIEM rules in a network of event processors. A computer system or server converts the SIEM rules to formal representations. The computer system or server generates rule abstraction of the formal representations, by using an abstraction function. The computer system or server constructs a finite automaton based on the rule abstraction. The computer system or server eliminates irrelevant transitions in the finite automaton to generate an optimized finite automaton. The computer system or server generates optimized formal rules, based on the optimized finite automaton. The computer system or server converts the optimized formal rules to optimized SIEM rules. The computer or server deploys the optimized SIEM rules in the network of the event processors.

  • Patent number: 9354278
    Abstract: This device and method use the complex impedance of a rechargeable battery to detect the state of the rechargeable battery. A computer determines the slope of the complex impedance at least two different frequencies in a diffusion region of the rechargeable battery when a straight-line approximation has been made, and compares the slope with a threshold value. If the slope is greater than or equal to the threshold value, the computer determines that the battery has a normal capacity balance, and if the slope is less than the threshold value, the computer determines that the battery has an abnormal unbalanced capacity. Furthermore, if the magnitude of an imaginary axis component of the complex impedance in the diffusion region of the rechargeable battery is greater than the threshold battery, the computer determines that the battery has an abnormal capacity balance, and if said magnitude is less than or equal to the threshold value, the computer determines that the battery has a normal capacity balance.
