Abstract: A method and system for detecting a fraudulent payment are described herein. The method can include detecting, at a server computer system, a request to perform a transaction between a merchant system and a customer of the merchant system, and in response to the detecting, determining, in real time one or more real time features corresponding to the transaction. The method may also include determining, by the server computer system, one or more batch features that correspond to one or more attributes associated with the transaction. The method may also include determining, by the server computer system, whether the payment is potentially fraudulent based on utilizing a model that includes inputs corresponding to the combination of the one or more real time features and the one or more batch features, and in response to determining that the payment is potentially fraudulent, performing, a remediation action associated with the transaction.

Abstract: A method and apparatus for machine learning model based fraud detection of transactions are described. The method may include determining, by a fraud detection system, a first block rate of a first fraud detection machine learning model (MLM) that scores transactions of a server computer system, wherein the fraud detection system blocks a transaction when a score generated for the transaction by the first fraud detection MLM does not satisfy a first threshold value. The method may also include accessing, by the fraud detection system, a second fraud detection MLM to be used by the fraud detection system for blocking future transactions. Furthermore, the method may include determining, by the fraud detection system, a second threshold value using a set of prior transactions input into the second fraud detection MLM that results in a second block rate of the second fraud detection MLM within a predetermined margin of the first threshold.

Abstract: Methods and apparatuses are provided for power control in a processor. The apparatus comprises a plurality of operational units arranged as a group of operational units. A power consumption monitor determines when cumulative power consumption of the group of operational units exceeds a threshold (e.g., either or both of the cumulative power threshold and the cumulative power rate threshold) during a time interval, after which a filter for issuing instructions to the group of operational units suspends instruction issuance to the group of operational units for the remainder of the time interval. The method comprises monitoring cumulative power consumption by a group of operational units within a processor over a time interval. If the cumulative power consumption of the group of operational units exceeds the threshold, instruction issuance to the group of operational units is suspended for the remainder of the time interval.

Abstract: Video signatures are generated when a small change in video information between consecutive frames N?1 and N is followed by a large change in video information between consecutive frames N and N+1. Information from frames N and/or N+1 is used to form a video signature.

Abstract: A microwave oven comprises a cooking cavity and a RF generation module configured to deliver microwave energy into the cooking cavity. A controller receives and processes a signal indicative of the current state of an associated energy supplying utility for determining whether to operate the microwave oven in one of a normal operating mode and a power saving mode in response to the received signal. A power source is operatively associated with the controller and the RF generation module, and is configured to receive a signal from the controller and cause the microwave oven to operate in normal operating mode or in power saving operating mode in accord with the signal.
