Abstract: This disclosure discloses an address translation method, apparatus, and system. The method includes: receiving, by a first address translation unit (ATU), an access request sent by a first virtual machine (VM), where the access request carries a first address and parameter information of the first address, and the parameter information of the first address includes an identifier of a target virtual function (VF); determining, by the first ATU, a matching relationship based on the parameter information of the first address and VF range description information in an address mapping table; and when an identifier of a target VF and the VF range description information are successfully matched, translating, by the first ATU, the first address into a second address based on the address mapping table.

Abstract: The present invention provides a method and an apparatus for determining an identity identifier of a face in a face image, and a terminal. The method includes: obtaining an original feature vector of a face image; selecting k candidate vectors from a face image database; selecting a matching vector of the original feature vector from the k candidate vectors; and determining, an identity identifier that is of the matching vector. In embodiments of the present invention, a face image database stores a medium-level feature vector formed by means of mutual interaction between a low-level face feature vector and autocorrelation and cross-correlation submatrices in a joint Bayesian probability matrix. The medium-level feature vector includes information about mutual interaction between the face feature vector and the autocorrelation and cross-correlation submatrices in the joint Bayesian probability matrix, so that efficiency and accuracy of facial recognition can be improved.

Abstract: A method and an apparatus for clearing a malicious power-consuming application, and a user terminal are provided. An application whose background working power consumption is not less than a power consumption threshold is determined as a malicious power-consuming application; and a wakelock occupying time of each application if a screen is turned off is periodically calculated, and if a background working application's wakelock occupying time is not less than a set time threshold, the application is determined as a malicious power-consuming application.
