Concept Drift Machine Learning
Concept Drift Machine Learning. Adopted from data and concept drifts in machine learning | towards data science. The term concept refers to the quantity to be predicted.
Concept drift is a term you seldom hear from companies selling ai & machine learning solutions, but it’s crucial to understand if you want to realise a sustained return on your machine learning investment. The generic way to monitor concept drift is depicted in the following image: This is particularly true in the world of machine learning models.
The Objective Of Machine Learning Models Is To Extract.
Contrary to data drift, where the data changes, concept drift occurs when the model’s predicted target or its statistical properties change over time. The fraudulent model above is an example of concept drift, where the classification of what is ‘fraudulent’ changes.

It Can Be Gradual (Expected), Sudden (You Get It), And Recurring (Seasonal).
The model performs worse on unknown data regions. The model is continuously monitored against a golden data set which is curated by human experts. Concept drift’s issue is a decisive problem of online machine learning, which causes massive performance degradation in the analysis.
We Can Decompose The Joint Probability P (X,Y) Into Smaller Components To Better Understand What Changes In These Components Can Trigger Concept Drift:
Data drift is a type of model drift where the properties of the independent variable(s) change(s). In predictive analytics and machine learning, concept drift means that the statistical properties of the target variable, which the model is trying to predict, change over time in unforeseen ways. As the incoming data drifts away from the historical data which was used for training, the relationships and correlations between features changes as well.
It Refers To Changes In The Production Data That Can Cause A Model's Generalization To Alter.
The generic way to monitor concept drift is depicted in the following image: Drift is an important concept in machine learning and artificial intelligence. A concept drift means changes of posterior probabilities between two situations.
Common Types Of Concepts Are Weather Patterns, Customer Preferences, Temperature And Behavioral.
Concept drift is a specific type of model drift, and can be understood as changes in the relationship between the input and target output. First, the training data set is collected and curated, then the model is trained on that. In machine learning and predictive analytics, the concept drift means the statistical properties of the target variable of the data, of which the model is trying to predict, changes over time in very unpredicted ways.
