Let’s get started by learning what AI agents are.
What are AI agents?
An AI agent is essentially a software robot designed to perform specific jobs, kind of like a virtual employee. They're digital assistants that can understand complex commands and complete sophisticated tasks for you. The key thing that makes an AI agent smart is its ability to learn over time based on interactions and experiences.
How AI agents work
AI agents operate by utilizing advanced machine learning algorithms and neural networks to analyze vast amounts of data, identify patterns, and make decisions or predictions without explicit human programming.
For example, you can see how they work in this demo video of the Lindy AI Meeting Prep Assistant:
Let's dive deeper into how these intelligent agents work and adapt.
1. Data ingestion and preprocessing
The first step for any AI agent is to gather data from its environment. This data can come from various sources, such as user inputs, sensors, or databases. Before the AI can use this data, it needs to be cleaned and preprocessed.
This involves:
- Data cleaning: Removing any errors, duplicates, or inconsistencies in the data. For example, correcting misspelled names in a customer list or removing duplicate entries from a sales database.
- Normalization: Converting the data into a standard format so that the AI agent can interpret it accurately. For example, customers' ages and income levels can be adjusted on a scale of 0 to 1 to ensure consistency during analysis.
- Feature extraction: Identifying and selecting the most relevant pieces of information from the data to use in the model. For example, you can look at a dataset of customer interactions and find purchase history and locations to predict future purchases.
2. Training the AI agent
Once the data is preprocessed, the AI agent undergoes training using large datasets to detect patterns and learn relationships between different data points.
There are three primary methods through which AI agents learn:
- Supervised learning: In supervised learning, the AI agent is trained on a labeled dataset where each input comes with a corresponding output. For example, an AI agent designed to identify spam emails is trained on a dataset of emails that are labeled as “spam” or “not spam.”
Over time, the agent learns to recognize patterns in the emails that indicate whether they are likely to be spam.
- Unsupervised learning: Here, the AI agent is fed data without any labels, meaning it must find patterns and relationships within the data on its own. For example, an AI agent used in market segmentation might analyze customer data to identify groups with similar buying behaviors, even though it doesn't have predefined categories.
- Reinforcement learning: In reinforcement learning, the AI agent learns through trial and error. It performs actions in its environment, receives feedback in the form of rewards or penalties, and adjusts its strategies accordingly. For example, an AI-powered robotic arm in a manufacturing plant might learn the most efficient way to assemble a product by receiving rewards for correctly placing parts and penalties for errors like misalignment or dropping components.
Over time, the robotic arm improves its precision and speed, optimizing the assembly process.
3. Model building and deep learning
AI agents use deep learning, which involves neural networks — a series of algorithms that attempt to recognize relationships in a set of data through a process that mimics the human brain.
Here’s how it works:
- Neural networks: Consist of layers of interconnected nodes ("neurons") that process information. The input layer receives the raw data, which passes through multiple hidden layers where the neural network assigns "weights" to various data features, helping the AI agent to make decisions.
- Backpropagation: A technique used during training to adjust weights in the neural network based on errors in the output, effectively teaching the AI agent how to improve its predictions. This process is repeated thousands or millions of times until the model's accuracy is satisfactory.
- Deep learning models: Include convolutional neural networks (CNNs) for image recognition, recurrent neural networks (RNNs) for sequence prediction (like text or speech), and transformers (such as GPT) for natural language understanding.
4. Decision-making process
Once trained, AI agents make decisions based on incoming data, using various strategies suited to their design. These strategies differ depending on how the agent is programmed to operate and the complexity of the tasks it needs to perform.
For example, some agents rely on simple, rule-based approaches to respond to immediate stimuli, while others use internal models to predict outcomes before acting. Certain agents are designed to pursue specific goals and adjust their actions to reach those objectives effectively.
Others evaluate multiple possible actions and select the one that offers the greatest overall benefit, balancing factors like speed, safety, or cost-efficiency.
In the coming section, we will explore these different decision-making methods in more detail, explaining how each type of agent chooses its actions and the advantages and limitations of each approach.
5. Continuous learning and adaptation
Many AI agents can continue to learn and adapt to new data after deployment, refining their models to improve performance over time. For example:
- Online learning: The AI agent updates its model in real time as it processes new data. This is especially useful in dynamic environments where the agent must adapt quickly, like stock trading or weather prediction.
- Batch learning: The AI agent retrains periodically on batches of new data, allowing it to incorporate recent trends or changes in the environment.
- Feedback loops: AI agents use feedback loops to monitor their performance and make adjustments. For instance, a customer service AI might analyze customer satisfaction ratings and adjust its responses to improve future interactions.
6. Deployment and integration
Once trained and tested, AI agents are deployed in their intended environment. They are integrated with existing systems or tools to start performing their tasks. For example:
- APIs (Application Programming Interfaces): Allow AI agents to interact with other software applications, like integrating a chatbot with a website.
- Cloud platforms: Enable scalability and provide the computational resources required for AI agents to handle large-scale tasks.
7. Real-time monitoring and updates
AI agents require constant monitoring to ensure they perform correctly and efficiently. This involves:
- Performance tracking: Analyzing the agent’s actions and results to measure success against predefined goals.
- Regular updates: Continuously update the agent’s algorithms and data sets to improve accuracy and adapt to new conditions or challenges.
Types of AI agents
Listen up because we’re about to give you the lowdown on all the main types of AI agents.
(One caveat: Several of these AI agent types can overlap, as is the case with utility-based and model-based agents in self-driving cars.)
1. Simple-reflex agents
Simple-reflex agents react to their environment using pre-set rules without learning or adapting from their actions.
How they work: These agents make decisions based solely on the current situation. They operate by using "if-then" rules, responding to specific inputs with predefined outputs without any memory of past events.
Here are some examples:
- Old-school chatbots: Respond to user queries with canned answers from a database without understanding or adapting to context.
- Basic security systems: Trigger alarms or lock doors when a motion sensor is activated, based purely on pre-set rules.
2. Goal-based agents
Goal-based agents are designed to achieve specific objectives by working step-by-step toward a goal.
How they work: These agents make decisions by evaluating which action will best help them achieve their defined goals. They are focused on long-term success but can struggle in unexpected situations.
Here are some examples:
- Game-playing AIs (like Deep Blue): Aim to win a game (e.g., chess) by following the rules and calculating the best possible moves.
- Automated stock trading systems: Execute trades to maximize profit based on predefined financial strategies.
3. Learning agents
Learning agents continuously improve by observing their environment and learning from their past actions.
How they work: These agents monitor their environment, experiment with different strategies, and adjust their behavior based on what works best. They learn from successes and mistakes to optimize future actions.
Here are some examples:
- AlphaGo: Learns to play Go by playing thousands of games and adapting its strategy based on outcomes.
- Self-driving cars: Improve driving techniques by learning from real-world driving experiences, like adjusting turns or braking more smoothly.
4. Model-based reflex agents
Model-based reflex agents use an internal model to make decisions based on how they perceive their environment.
How they work: These agents maintain a representation of their environment and use it to predict the outcomes of their actions. They react to the current state by referring to their internal model, which can be updated with new data.
Here are some examples:
- Robot vacuum cleaners (like Roomba): Use a map of the house to navigate around obstacles and clean efficiently.
- Self-parking cars: Build a model of the parking space and calculate the best route to park autonomously.
5. Utility-based agents
Utility-based agents evaluate all possible actions and choose the one that maximizes their utility or usefulness.
How they work: These agents assess various potential actions and select the one that offers the highest value or chance of success, balancing multiple objectives to find the optimal outcome.
Here are some examples:
- Self-driving cars: Choose the safest and fastest route based on real-time traffic data.
- Recommendation systems: Suggest products that align with a user's preferences and past behavior to maximize engagement or sales.
6. Multi-agent systems
Multi-agent systems consist of multiple AI agents working together to solve complex problems that a single agent cannot handle alone.
How they work: These agents collaborate by sharing information, dividing tasks based on specialization, and coordinating actions to achieve a common goal. Their interaction can result in emergent behavior, where simple rules lead to complex, coordinated outcomes.
Here are some examples:
- Supply chain management systems: AI agents optimize inventory levels, predict demand, and coordinate logistics for efficient product delivery.
- Disaster response networks: Multiple AI agents collaborate to assess damage, manage rescue efforts, and allocate resources during emergencies.
And yes, you’ve guessed it: Lindy functions as a multi-agent system, enabling different AI agents to coordinate and share information to complete tasks more effectively.
