Data drift machine learning

WebConcept drift. In predictive analytics, data science, machine learning and related fields, concept drift or drift is an evolution of data that invalidates the data model. It happens when the statistical properties of the target variable, which the model is trying to predict, change over time in unforeseen ways. WebAug 3, 2024 · Concept Drift. When we train a machine learning model on data, the model learns a function that maps the features to the target variable. As previously stated, if all things were static and nothing evolved over time, then we’d expect the relationship from the features to the target to hold true, thus the model should perform as it always has.

WebSep 18, 2024 · This blog discusses how to detect and address model drift. Types of Drift in Machine Learning. Model drift can occur when there is some form of change to feature data or target dependencies. We can broadly classify these changes into the following three categories: concept drift, data drift, and upstream data changes. Concept Drift WebConcept drift (CD) in data streaming scenarios such as networking intrusion detection systems (IDS) refers to the change in the statistical distribution of the data over time. There are five principal variants related to CD: incremental, gradual, recurrent, sudden, and blip.
