Abstract: A method of detecting Android malware based on a heterogeneous graph and an apparatus thereof are provided, including: constructing a target heterogeneous graph according to entities and entity relationship information extracted from an application to be tested; determining a KL distance between any two meta-paths, and taking the meta-paths in which the KL distance is greater than a preset threshold as a plurality of finally selected meta-paths; carrying out, by RBM, feature fusion on the plurality of meta-paths, and adjusting, by an automatic encoder, fusion parameters of initial fusion vectors to meet a predetermined condition to obtain a plurality of fusion feature vectors; inputting the plurality of fusion feature vectors into a trained Deep Neural Network (DNN) for classification to obtain a final classification result, and determining whether the application to be tested is Android malware according to the final classification result.

Abstract: An assembling device is disclosed. The assembling device is used to assemble a plastic frame and a back plate together and includes: a pressing mechanism configured to press a region of the plastic frame; and a supporting device. The supporting device includes: a supporting platform configured to support the back plate and the plastic frame; and a supporting frame configured to support the pressing mechanism. The pressing mechanism is configured to contact the plastic frame at least one contact point, and a direction of a resultant force of forces applied at the at least one contact point by the pressing mechanism is at an acute angle with respect to a plane where a top surface of the plastic frame lies.
