• Regression models predict numerical values.
• Clustering models group similar data.
• Neural networks solve complex learning tasks.
• Transformers power modern language models.

Step 5: Train the Model

Training involves exposing the AI model to large datasets so it can recognize patterns and relationships.

The model adjusts its internal parameters over multiple iterations to minimize prediction errors.

Step 6: Evaluate Performance

After training, evaluate the model using testing data.

Common evaluation metrics include:

• Accuracy
• Precision
• Recall
• F1 Score
• Mean Squared Error (MSE)
• ROC-AUC

Performance testing ensures the model generalizes well to new data.

Step 7: Deploy the Model

Once validated, deploy the model into production.

Deployment options include:

• Cloud platforms
• Mobile applications
• Web applications
• Enterprise software
• Edge devices

Users can now interact with the AI model in real-world environments.

Step 8: Monitor and Improve

AI models require continuous monitoring to maintain performance.

Regular maintenance includes:
