Abstract Aiming at the problem of multi-view high-resolution range profile (HRRP) target recognition under open set conditions, we proposed an method based on joint sparse representation (JSR), which solves low rate traditional methods conditions. This is applied to background radar single-station observation. JSR used solve reconstruction error HRRP by over-complete dictionary, while extreme v...

Deployed into an open world, object detectors are prone to open-set errors, false positive detections of classes not present in the training dataset.We propose GMM-Det, a real-time method for extracting epistemic uncertainty from identify and reject errors. GMM-Det trains detector produce structured logit space that is modelled with class-specific Gaussian Mixture Models. At test time, errors i...

As information technology advances, it provides user convenience but also has more vulnerabilities than ever before. In particular, attackers use advanced techniques to perform new attacks. cyber security, such attacks are defined as unknown and target previously undetected or excavate gaps in the system. Because these unidentified unanalyzed, they difficult identify signature-based misuse dete...
