What is an essential characteristic of curriculum learning in machine learning?

An essential characteristic of curriculum learning in machine learning is the approach of training on progressively more complex tasks. This methodology mirrors human learning, where individuals often grasp simpler concepts before moving on to more challenging ones. By starting with easier tasks, models can build foundational knowledge and gradually incorporate more difficult tasks, enhancing their ability to learn effectively and efficiently. This structured progression helps to maintain the model's focus and reduces the risk of overwhelming it with complexity too soon.

Curriculum learning allows for a more structured training process, where the model is given a clear pathway to develop its skills. This can lead to improved performance and reduced training time, as the model can leverage its understanding from simpler tasks to tackle more complex scenarios.
