Validation: This step ensures that the model generalizes well to unseen data, preventing overfitting.

Training Methods

Several approaches are utilized during training:

Supervised Learning: Learning from labeled data to make predictions or classifications.
Unsupervised Learning: Finding patterns in data without labels, useful for clustering and dimensionality reduction.
Reinforcement Learning: Learning through trial and error, maximizing rewards based on actions taken in an environment.

The Role of Inference in AI

Inference follows training and involves making predictions or decisions based on the learned model. It is the operational phase where the trained model is applied to new data.

Key Aspects of AI Inference
