Understanding the Training Process

In the training process, an AI model learns from labeled data, grasping patterns and relationships to make predictions on new, unseen data. It starts with an **initializing** phase, where the model’s parameters are set to random values. Next, the model **iteratively** refines these parameters by comparing its predictions with the known labels in the training data, using a specific algorithm. The model **adjusts** its parameters at each iteration to minimize the difference between its output and the expected values.

*Training an AI model is analogous to a student learning from practice exercises to improve their performance.*
