How does an already trained machine learning model takes new scope of data into account?

Tuesday, 06 May 2025 by fabien lambergeon

When a machine learning model is already trained and encounters new data, the process of integrating this new scope of data can take several forms, depending on the specific requirements and context of the application. The primary methods to incorporate new data into a pre-trained model include retraining, fine-tuning, and incremental learning. Each of these
