Summary: Deep neural networks have achieved remarkable performance but are vulnerable to adversarial examples, leading to the need for evaluating and benchmarking model robustness. Current evaluations lack an understanding of defense limitations and weaknesses, resulting in an arms race between attack and defense. To address this, the authors propose a comprehensive evaluation framework with 23 metrics that consider both data and model perspectives. Through large-scale experiments, they demonstrate the effectiveness of their framework in inspiring deeper understanding and improving model robustness.

Summary: This paper presents an automatic dense correspondence method for matching the mesh vertices of two 3D shapes under near-isometric and non-rigid deformations. The method combines three types of graphic structure information and includes three major steps: describing the vertices based on three types of graphical information, formulating the match as an optimization problem, and resolving the optimal solution using the projected descent optimization procedure. The method achieves superior performance to existing methods in quantitative and qualitative evaluations on challenging 3D shape matching datasets.

Summary: A disturbance estimation and rejection technique based on the improved active disturbance rejection control (IADRC) approach is proposed and verified on a ground two-wheel differential drive mobile robot. The IADRC is adopted to eliminate the effect of system uncertainties and external torque disturbance on both wheels. A novel nonlinear sliding mode extended state observer (NSMESO) is used to observe and cancel the generalized disturbance in real-time. Numerical simulations show a significant reduction in the ITAE index for both wheels, validating the efficacy of the proposed dynamic speed controller in damping the chattering phenomena and providing high insusceptibility to torque disturbance.

Summary: In this paper, a Nonlinear Higher Order Extended State Observer (NHOESO) is proposed to replace the Linear Extended State Observer (LESO) in Conventional Active Disturbance Rejection Control (C-ADRC) solutions. The NHOESO extends the standard LESO by incorporating a two-term smooth nonlinear function with saturation-like characteristics. It allows for precise observation of generalized disturbances with higher-order derivatives. The stability of the NHOESO is analyzed using the Lyapunov method. Simulation results on an uncertain nonlinear Single-Input-Single-Output (SISO) system with time-varying external disturbances demonstrate the effectiveness of the proposed NHOESO in handling generalized disturbances compared to other ESOs.

Summary: This research paper models a new 3-D chaotic jerk system with a stable equilibrium and shows that it exhibits hidden attractors. Bifurcation analysis is performed on the system, revealing its multistability with coexisting attractors. Backstepping control is applied to synchronize a pair of new jerk systems, with Lyapunov stability theory used to establish synchronization results. The FPGA design of the jerk system is implemented using the FPGA Zybo Z7-20 development board, and experimental attractors are found to align with simulation results.

Experimental results demonstrate that this algorithm achieves a good bias-variance tradeoff and competitive classification performance compared to other high-dependence or ensemble learning algorithms.
