Concept Drift Handling

======================

In this problem, you will implement a concept drift handling system to adapt to changes in the distribution of a dataset over time. The system should be able to detect concept drift and update the model accordingly.

Example:

Suppose we have a model that predicts house prices based on features like number of bedrooms and square footage. We want to handle concept drift by updating the model's parameters.

Constraints:

The model's parameters should be updated based on the new data. The updated model should be able to make predictions on new data.
