Research on extended access control mechanism in online social network
Published 2021-10-01“…Aiming at the problem of inability to extend control over the data published by users in social networks, an extended access mechanism based on privacy labels was proposed.This mechanism granted users and data different types of labels based on the number of user relationship hops and resource forwarding hops, so as to achieve fine-grained extended access control to the data.The generation algorithm and distribution method of privacy labels were proposed.The constraint rules of privacy label were designed and the possible policy conflicts were analyzed.Finally, the test proves that the mechanism achieves fine-grained extended control in social networks, and proves its security and validity of the mechanism.…”

Research on medical small sample data classification based on SMOTE and gcForest
Published 2023-06-01“…Aiming at the problem of poor classification performance in traditional machine learning models caused by shallow model structure and complex data characteristics in small medical sample data, an combine multi- grained improved cascade forest (cgicForest) model was proposed.It enhances the representation learning ability of the model by adding random sampling into the multi-grained scanning and optimizing the transformation features.It also enhances the model's classification ability by updating the cascade forest’s hierarchical structure.Considering category imbalance problems in datasets, the safe-borderline-SMOTE (SBS) algorithm was proposed to dynamic interpolate around the few class samples belonging to the safety boundary, which can improve the quality of training data.The cgicForest was applied for training and learning, thus the SBS-cgicForest classification model was obtained which can support imbalanced medical small samples data.The model is used on three medical datasets for classification experiments.The results show that the performance indexes of the cgicForest model in the classification of medical small sample data with complex characteristics have increased by 4.1~5.4 percentage points, compared with the multi-grained cascade forest (gcForest) model.The performance indexes have increase by 6.6~11.2 percentage points after the combination with SBS algorithm, the F<sub>1</sub> score was 2~2.5 percentage points higher than that obtained by traditional sampling methods.It provides a reference for solving the classification problem of small medical sample data, and includes support for internet of things applications in smart medical scenarios.…”

Further investigation on microstructure refinement of internal crack initiation region in VHCF regime of high-strength steels
Published 2019-05-01“…The profile samples prepared by focused ion beam (FIB) in crack initiation region (CIR) and fish-eye (FiE) region of failed specimens subjected to rotary bending (RB) and ultrasonic axial (UL) fatigue testing with various stress ratios (R) were observed by transmission electron microscopy (TEM) with selected area electron diffraction (SAD) detection for two high-strength steels. The grain size and the thickness of nanograin layer along the crack growth path in CIR underneath fine-granular-area (FGA) were measured for the cases of R < 0, and a normalized quantity d* based on the detected SAD patterns was introduced to quantitatively demonstrate the variation of the grain size. …”
