机器学习4--Imbalance data:重复采样;合成数据;集成算法 数据不平衡是指在数据集中,一类(或多类)样本特别多而另一类(或多类)样本特别少。这种问题广泛存在于金融欺诈、医学检测、网络入侵、异常检测等场景中。 由于多数类的样本在总样本占据的比重太多,少数类样本被忽视,训练出来的分类器更偏向于多数类导致分类器的...

SMOTE ("SyntheticMinorityOversamplingTEchnique") is an oversampling technique that works by drawing lines between the minority data points and generate data throughout those lines as shown in the figure below. We will use thesmote-variantsPython library which is a package that includes 85 variants...

Behavioral data analysis Markerless pose estimation were based on Faster-RCNN and HRnet using mmopenlab framework, annotations were semi-automatically performed, and training was initiated using customized configuration file (written by Guangwei Zhang, in Python 3.7). For the forced swimming test and ...
The faults were modeled using Python programming language [46] according to fault modeling methods provided in Refs. [47,48] and introduced into the verified prototype medium office building model. 14 faults, including control, sensor, packaged air conditioner and VAV terminal faults, were simulated...
Among them, SMOTE, Borderline-SMOTE (BLSMOTE), ADASYN, and MWMOTE were implemented using the smote-variants python tool package [50]. All methods are oriented toward data balance. In parameter settings, k1=5 Conclusion A novel oversampling method called NanBDOS has been proposed in this paper...
