Abstract: A method, apparatus and computer program product to defend learning models that are vulnerable to adversarial example attack. It is assumed that data (a “dataset”) is available in multiple modalities (e.g., text and images, audio and images in video, etc.). The defense approach herein is premised on the recognition that the correlations between the different modalities for the same entity can be exploited to defend against such attacks, as it is not realistic for an adversary to attack multiple modalities. To this end, according to this technique, adversarial samples are identified and rejected if the features from one (the attacked) modality are determined to be sufficiently far away from those of another un-attacked modality for the same entity. In other words, the approach herein leverages the consistency between multiple modalities in the data to defend against adversarial attacks on one modality.

Abstract: A closing control method for a high-voltage DC circuit breaker. The method comprises: closing breaking units of the transfer branch (2) group by group, then closing the main branch (1), and finally open the transfer branch. During the process of closing the breaking units of the transfer branch group by group, determine whether there is a fault in the power transmission system after closing current breaking unit group. if there is no fault, proceed to close the next breaking unit group until all breaking unit groups are closed before proceeding to the next step; if there is a fault, all the breaking units that have been closed are opened and the closing operation is ended. The method can pre-charge the power transmission system during the closing process of the high-voltage DC circuit breaker, and lower the overvoltage and system oscillation caused by the closing operation.
