4. Training AI Models
During training, the AI model analyzes large datasets to understand patterns and relationships.
The system adjusts its internal parameters to improve performance and accuracy.
Once trained, the model can analyze new information and make decisions.
5. AI Decision-Making
After training, AI systems can:
- Predict outcomes
- Classify data
- Provide recommendations
- Automate tasks
This is where AI becomes useful in real-world applications.
What Are AI Agents?
AI agents are intelligent programs that can observe their environment, make decisions, and perform actions to achieve specific goals.
In artificial intelligence, an agent interacts with its environment through sensors and actuators.
AI agents typically perform these steps:
- Perceive the environment
- Process information
- Make decisions
- Take action
AI agents are commonly used in:
- Chatbots
- Smart assistants

2. Model-Based Agents
Model-based agents maintain an internal representation of the environment.
This helps them make better decisions in dynamic situations.
Example:
Navigation systems and autonomous vehicles.
3. Goal-Based Agents
Goal-based agents make decisions to achieve specific objectives to evaluate different possible actions before selecting the best one.
Example:
AI route planners.
4. Utility-Based Agents
Utility-based agents choose the action that provides the highest benefit.
They analyze different outcomes and select the optimal solution.
Example:
AI financial decision systems.
5. Learning Agents
Learning agents improve their performance over time.
They adapt based on experience and feedback.
Examples include:
- Recommendation engines
- AI chatbots
- Personalization systems
These are the most advanced AI agents used today.
