硬示例挖掘方法通常可以改善对象探测器的性能，这些探测器患有不平衡的训练集。在这项工作中，将两种现有的硬采矿方法（LRM和焦点损失，FL）改编成最先进的实时对象检测器Yolov5。广泛评估了提出的方法改善硬性示例性能的有效性。与使用原始损失函数相比，该方法将MAP提高3％，而在2021 Anti-UAV挑战数据集上单独使用硬挖掘方法（LRM或FL）相比，MAP和1-2％左右。

Ranking intuitionistic fuzzy sets with distance based ranking methods requires to calculate the distance between intuitionistic fuzzy set and a reference point which is known to have either maximum (positive ideal solution) or minimum (negative ideal solution) value. These group of approaches assume that as the distance of an intuitionistic fuzzy set to the reference point is decreases, the similarity of intuitionistic fuzzy set with that point increases. This is a misconception because an intuitionistic fuzzy set which has the shortest distance to positive ideal solution does not have to be the furthest from negative ideal solution for all circumstances when the distance function is nonlinear. This paper gives a mathematical proof of why this assumption is not valid for any of the non-linear distance functions and suggests a hypervolume based ranking approach as an alternative to distance based ranking. In addition, the suggested ranking approach is extended as a new multicriteria decision making method, HyperVolume based ASsessment (HVAS). HVAS is applied for multicriteria assessment of Turkey's energy alternatives. Results are compared with three well known distance based multicriteria decision making methods (TOPSIS, VIKOR, and CODAS).

自动日志文件分析可以尽早发现相关事件，例如系统故障。特别是，自我学习的异常检测技术在日志数据中捕获模式，随后向系统操作员报告意外的日志事件事件，而无需提前提供或手动对异常情况进行建模。最近，已经提出了越来越多的方法来利用深度学习神经网络为此目的。与传统的机器学习技术相比，这些方法证明了出色的检测性能，并同时解决了不稳定数据格式的问题。但是，有许多不同的深度学习体系结构，并且编码由神经网络分析的原始和非结构化日志数据是不平凡的。因此，我们进行了系统的文献综述，概述了部署的模型，数据预处理机制，异常检测技术和评估。该调查没有定量比较现有方法，而是旨在帮助读者了解不同模型体系结构的相关方面，并强调未来工作的开放问题。
