What is an AI Agent?

An AI agent is an autonomous software system that can perceive its environment, make decisions, and take actions to achieve specific goals. These agents leverage artificial intelligence (AI) and machine learning (ML) technologies and most importantly the Natural Language Processing (NLP) to operate independently and understand the instructions or goal to be achieved.

AI agents consist of multiple capabilities which make it stand out from other AI, includes:

• Perception: The ability to collect data from its environment through sensors or other means like text inputs, documents, or even from a database.
• Reasoning: The act of thinking about something logically in order to draw conclusion or make decision. To learn more about reasoning, check out our blog on Prompt Engineering: Mastering the Art of Generative AI.
• Learning & Adaptation: The agent continuously learn from the results of its actions with the support of Large Language Model (LLM) and adjusts its behavior to improve performance over time. Learn more about LLM on Unveiling the Power of LLM: Shaping the AI Landscape.
• Acting: AI agent can taken necessary steps to execute its chosen course of action in the real world based on the gathered information and the reasoning about the situation.
• Objective: AI agents often designed with a clear objectives or goals as the expected outcome which could be ranged from simple tasks to more complex ones line optimizing business operation.
• Autonomy: The ability to operate independently, making decisions and taking actions without the constant supervision or intervention of human users. This is often facilitated through the use of Robotic Process Automation (RPA), which interact with applications, just like a human would, and requires defined rules to function.

AI Agent Workflow

Other than using the single agents itself, it is also common to connect multiple agents or APIs to facilitate tasking solving process or tackle more complex tasks. This connection of multiple agents or APIs are usually named as Multi-agent System (MAS) or in simple words, agentic workflow. There are a few keys that make workflow possible to solve more complex tasks:

• Data Integration: AI agent workflow usually start with the seamless integration of data from various sources, such as databases, APIs, and real-time sensor inputs. This data serves as an extra data source for the agent's decision-making and learning processes.
• Decision Points: Every AI agent are specialized with a specific subtask as a crucial decision point in the whole workflow. Through connecting multiple "decision points", the workflow will be possible to automate complex decisions which originally needs extensive human analysis
• Feedback Mechanisms: AI agents incorporate feedback mechanisms that allow them to learn from their experiences and continuously improve their performance. This feedback can come from direct user input, monitoring of outcomes, or even from other agents which gives a review on its work.

‍

Types of AI Agent

AI agents can be categorized into several different types, each with its own unique characteristics and capabilities.

1. Simple Reflex Agents

Simple reflex agents ignore the percept history and base their decisions solely on the state of their environment at the time, without taking long-term effects or planning into account. Therefore, this type of agents will have limited intelligence and not adaptive to the changes in the environment.

2. Model-Based Reflex Agents

These agents maintain an internal model of their environment, where model means "the knowledge about the world". Therefore, these agents are capable of tracking events and operating in partially visible environments which depends on the size of the model.

3. Goal-Based Agents

These agents add a goal to the model-based reflex agent to further extend its capabilities. With the goal they can decide on the best actions to take among all actions to meet the specific goal. This process of choosing the goal simulate the planning process and allow the agents to be proactive.

4. Utility-Based Agents

Further build on top of the goal-based agents, utility-based agents provide another component — utility, to measure the level of success on achieving the goal. Therefore, when there are multiple actions that could possibly achieve its goal, it is possible to differentiate between the actions with utility and choose the best step to take.

5. Learning Agents

These agents are designed to learn and improve their performance over time, adapting their behavior based on feedback and new experiences. For more details on different types of AI agents, please visit here for more information.

Not really. ChatGPT is a LLM developed by OpenAI. Although It do have some characteristic of AI agents such as autonomy (generating response without relying on preprogrammed script), goal-oriented (assist users by providing helpful information, answering questions, and completing tasks), and perception (make use of the inputs to generate corresponding responses), it still miss some important capabilities that AI agents have. For example, it cannot really learn or update its knowledge in real time, and it is not adapt with tools or communicate with other AI agents on it own. Therefore, ChatGPT is more like a foundation of an AI agent that make it possible to understand language rather than an AI agent itself.

2. Is AI agent biased?

Possible. AI agent could be biased mainly due to the following perspectives:

• Training Data: The data used to train AI models can contain human-created biases, stereotypes, and prejudices. If the training data reflects societal biases, the AI agent may learn and perpetuate those biases.
• Algorithm: The machine learning algorithms used to train AI agents can inadvertently amplify or introduce biases, even if the training data is unbiased. Decisions made by AI agents are ultimately based on the algorithms powering them, which may have inherent biases.
• Developer: The humans who design, develop, and deploy AI agents may have their own biases and assumptions that get reflected in the final system. Lack of diversity and inclusive practices in AI development teams can contribute to biased outputs.

3. What are some more potential applications of AI agents?

AI agents have a wide range of applications, including personal assistants, chatbots, autonomous vehicles, robotic systems, recommendation engines, financial trading, and medical diagnosis. They can excel at tasks that require rapid data processing, pattern recognition, or complex decision-making.

4. How AI agents learn and improve over time?

Agents can use feedback from their environment, interactions with users, or new data to refine their models and improve their performance. Common methods include reinforcement learning, where agents learn from trial and error, and deep learning, where neural networks can be continuously updated with new information.
