You are where you have been: Sybil detection via geo-location analysis in OSNs
TLDR
In this study, we introduce a novel sybil detection approach by exploiting the fundamental mobility patterns that separate real users from sybil ones. Expand

Efficient Adversarial Training With Transferable Adversarial Examples
TLDR
We propose a novel adversarial training method called ATTA (Adversarial Training with Transferable Adversarial examples) that can enhance the robustness of trained models and greatly improve the training efficiency by accumulating adversarial perturbations through epochs. Expand

Smoke Screener or Straight Shooter: Detecting Elite Sybil Attacks in User-Review Social Networks
TLDR
We define, characterize, and detect elite Sybil attacks, which recruits organically highly-rated accounts to generate seemingly-trustworthy and realistic-looking reviews on popular URSN services. Expand

Analyzing the Interpretability Robustness of Self-Explaining Models
TLDR
We evaluate the interpretability robustness of SEMs and show that explanations provided by SEMs as currently proposed are not robust to adversarial inputs. Expand

Experimental Study and Numerical Analysis on the Vibration Characteristics of a Terraced Slope along an Embankment Section of a High-Speed Railway
The characteristics of the vibrations induced by the passage of a high-speed train do not only depend on the train speed, axle load, and track irregularity but also depend on the properties of theExpand
Study on the service life prediction of freeze–thaw damaged concrete with high permeability and inorganic crystal waterproof agent additions based on ultrasonic velocity
Abstract Based on a rapid freeze–thaw test of inner-doped silicon-ash concrete specimens that were coated using three different externally coated inorganic coating methods, ultrasonic wave velocityExpand
Cyclic oxidation behavior of NiCoCrAlY/YSZ@Ni composite coatings fabricated by laser cladding
Composite coating on GH4169 alloy is prepared by laser cladding yttria-stabilized zirconia (YSZ)@Ni core–shell powders mixed with NiCoCrAlY alloy powders. The cyclic oxidation behavior of theExpand
