Sudden Drift:典型例子就是这次疫情,瞬间击穿了大量预测模型 Gradual Drift: 例如电视的销量预测,随着人们用手机,用电脑,电视的销量逐渐发生了变化。 Incremental Drift: 新概念取代旧概念,例如手机的使用预测,过去是用来接打电话发短信,现如今逐渐赋予更多功能更高的角色。 Reoccurring Concepts: 旧概念重新发生。例如疫...

drift understanding(when, how, where it occurs) anddrift adaptation(reaction to the existence of drift) as shown in Fig. 2. These will be discussed in Sections 3, 4, and 5.
The system adapts to the increasing imbalance of the training data, as reflected by a decrease (increase) of the class-wise error for the over-represented (under-repre- sented) class, respectively. The weighted overall error track also decreases, i.e., the presence of class bias ...

This task finds wide application in our life, so it has been attracting great attention of researchers....
Newly, the concept drift is considered as a challenging data imbalance that should be ignored by the NDMs, and only system changes and outliers represent novelty. The field of application for such NDMs is broad. For example, the method can be used as a supportive method for real-time system...
Attention must also be given to concomitant drivers of brain dysfunction, such as decreased cerebral perfusion, severe hypoxaemia, sepsis, high temperature, electrolyte imbalance, sleep disturbances and deliriogenic medications. Short-term sedation may be required while these precipitants are corrected. ...
