What is an AI Agent and Why AI Agents are Important
An AI agent is a computer program designed to assist people by performing tasks and answering questions. The key term here is helping people. AI agents learn from various language inputs to help with everyday tasks, like managing emails and scheduling appointments.
Tasks can range from setting reminders and managing schedules to providing information like weather updates or news. AI agents are programmed to understand and respond to human language, making interactions with them more natural and user-friendly.
Types of AI Agents: Assistive vs. Autonomous and Their Use Cases
There are many AI agents, including assistive and autonomous agents. An example of assistive agents is those that can be embedded within employee tools to help them with personalized tasks specific to their role.
Meanwhile, autonomous agents can understand and respond to customer inquiries without human intervention. This is done by using an agent builder, like Agentforce, to create agents that operate dynamically instead of following predefined rules triggered by changes in data and automations.
Understanding How AI Agents Work
Before building an AI agent, you must know the basic working principles. Having a fundamental grasp of their operations, you can better assess their capabilities and determine the resources required to develop an AI agent.
Training on Data
AI agents train on massive amounts of data. This data could be anything relevant to your product or service, such as:
- Customer purchases
- Website Traffic
- User preferences
- Healthcare records
Finding Data Patterns
Over time, the agent finds patterns in data that give insights into how things work. For example, an AI agent in an e-commerce store might discover that people buying running shoes often buy them with sports socks, which can be used to make product recommendations.
Performing Actions and Goals
AI agents take actions that meet your expected outcomes based on what they learn and what you instruct them to do. For instance, you can build your custom AI agent for customer service. When a customer submits a ticket, it can automatically categorize the submission based on keywords and other parameters.
For common issues with clear solutions, your AI agent can provide an automated response with the following:
- Troubleshooting steps
- Relevant FAQs
- Links to your existing articles
Then, you can configure it to route more complex complaints to your human staff intelligently.
Types of AI Agents: What's Out There?
You can choose from many AI agents depending on your industry and application. Here are the main types:
Simple Reflex Agents
These are the most basic types. They react to their environment based on pre-programmed rules.
Model-Based Reflex Agents
A step up from simple reflex agents, these build an internal model of their environment. Instead of simply reacting to triggers, they refer to their model before acting.
Goal-Based Agents
These agents have specific goals in mind and actively work towards them. They can plan their actions and consider different options to achieve their objectives.
Utility-Based Agents
These agents evaluate different options based on a predefined “goodness” or utility measure. For instance, a recommendation system might consider user preferences and product popularity to suggest the most valuable items.
Learning Agents
As the name suggests, these agents can improve their performance by learning from experience. For example, an AI spam filter that gets better at identifying spam emails as it sees more examples is a learning agent.
Why AI Agents Matter
AI agents are critical in improving our daily lives and accomplishing particular objectives.
They can:
- Lowering the human labor required to complete routine operations increases production and efficiency.
- Analyze enormous volumes of data to offer conclusions and suggestions that support decision-making.

How to Build an AI Agent for Smarter Automation & Decision-Making
Building an AI Agent: The First Steps
Building and training an AI agent involves teaching it to understand and respond to human language in a valuable and relevant way. Your data is at the heart of everything from generative AI to conversational AI. Training incorporates several key concepts from the fields of artificial intelligence, particularly machine learning and natural language processing.
Natural Language Processing
Natural language processing is a branch of AI that deals with the interaction between computers and humans through natural language. The aim is for computers to process and understand large amounts of natural language data. In the context of an AI agent, NLP enables the system to understand, interpret, and generate human language in a natural and meaningful way.
Machine Learning
Machine learning is an AI that allows systems to automatically learn and improve from experience without being programmed. When training an AI agent, machine learning algorithms use historical data (examples of human interactions) to find patterns and make decisions. The more data the AI processes, the better it gets at predicting and responding to user requests.
Data Labelling
Data labelling is a key step in training AI. Humans annotate data by adding meaningful tags or labels to the raw data so the AI can understand it. For example, in training an AI agent, data labelling might involve tagging parts of speech in sentences, identifying the sentiment of a text, or categorizing queries into topics. This labelled data then guides the AI in learning from and using these labels to understand the context and intent behind user inputs.
1. Define the Purpose and Scope of Your AI Agent
The first step in building an AI agent is clearly defining what you want it to do. This involves deciding on the specific tasks and functions the agent will perform.
Here’s how to approach this:
Defining Your AI Agent’s Purpose and Key Functions
Determine the tasks and functions of the AI agent. List the problems you want the AI agent to solve or the tasks you want it to handle.
- Do you want an autonomous agent?
- Do you need it to answer customer queries, help users shop online, or provide information about your business?
Your AI agent’s functions should align with the needs it aims to fulfill. For instance, do you need a virtual shopping agent? This agent helps users navigate online shops, offering personalized advice based on user preferences and past shopping behavior. It can suggest:
- Gift ideas
- Find the best deals
- Help with fashion choices
Understanding Your Target Audience for AI Agent Development
Identify your target audience. Different users have different expectations and ways of interacting with technology. For example, an AI agent designed for medical professionals might need to understand and use medical terminology accurately.
Defining Use Cases to Shape Your AI Agent’s Features
Consider use cases or specific situations in which your AI agent will be used. Determining these can help clarify what features and capabilities are necessary. For instance, a customer service chatbot must handle:
- Inquiries
- Complaints
- Transactions
At the same time, a virtual shopping agent should be able to suggest:
- Products
- Compare prices
- Understand user preferences
2. Pick a Platform
There’s no shortage of AI agent platforms to choose from. While I won’t compare platforms here because, admittedly, I’m partial to ours – I can share a few key factors to consider when selecting the right platform for your project: Make sure you pick an AI platform that:
- Has a broad swath of educational resources. There will always be a learning curve, so ensure you’re well-equipped.
- Matches your intent. Don’t pick a platform that specializes in customer service if you want a sales bot or a multi-agent system.
- Includes a free tier, so you can test it out before (or without) making a financial commitment. Once you pick a platform, you can start building your AI agent.
3. Collect and Prepare Training Data
Like a student learns from textbooks, an AI agent learns from data. If the data is incorrect or of poor quality, the AI will learn the wrong things and make mistakes. High-quality data ensures the AI can accurately understand and process user inputs. You need to gather data reflecting user interactions to train your AI agent.
This could include:
- Text transcripts: Collect transcripts of conversations from chat logs, support tickets, or emails that are similar to the expected interactions with the AI.
- Voice recordings: If the AI responds to spoken commands or inquiries, voice recordings are essential to help it understand different accents, intonations, and speech patterns.
- Interaction logs: Data from previous interactions with similar systems can provide insights into user behaviors and common queries or commands.
Data Preparation and Labeling for AI Training
Once you have your data, it needs to be prepared for training by cleaning it. This involves removing irrelevant or incorrect data, correcting errors, and ensuring consistency across the dataset, such as fixing typos in text transcripts or filtering out background noise in voice recordings. Label it. This is about adding labels—tags or metadata—to describe what each piece of data represents. For instance, labelling a text with the user’s intent, such as “booking a flight” or “asking for store hours,” helps the AI understand the context and purpose of user inputs.
4. Choose the Right Machine Learning Model
This step involves selecting the right machine learning model to determine how well your AI can learn from data and perform its tasks. There are two types of machine learning models:
- Neural networks: These are powerful models that mimic how human brains operate. They are particularly good at processing large amounts of data and recognizing patterns, making them ideal for understanding and generating human language.
- Reinforcement learning: This model learns through trial and error, using feedback from its actions to improve over time. It's useful for AI agents that need to make decisions or optimize their behaviour based on user interactions.
Choosing the Right AI Model for Your Agent’s Needs
So, how do you choose the appropriate model? Consider the AI agent’s functions and tasks you want it to perform. For example, a neural network might be the best choice if the agent needs to understand and generate human-like responses. Consider the data you collected. Neural networks require large amounts of data to train effectively, while reinforcement learning is suitable for scenarios where the AI can learn from ongoing user interactions.
Leveraging Pre-Trained Models for AI Agent Development
You also have the option of pre-trained models. These are models developed and trained by researchers on large datasets. They can be a great starting point because they have already learned a lot of general information about the language and human interactions. Here are some examples of pre-trained models:
- GPT (Generative Pre-trained Transformer): This model is excellent for generating text and can be fine-tuned to perform specific tasks, such as answering questions or writing content.
- BERT (Bi-directional Encoder Representations from Transformers): Known for its ability to understand the context of a word based on its surroundings, making it useful for tasks that require a deep understanding of language, such as sentiment analysis or translation.
Fine-Tuning Pre-Trained Models for Specialized AI Tasks
While pre-trained models are broadly knowledgeable, they might not specialize in the tasks your AI agent needs to perform. You’ll have to fine-tune them. Fine-tuning involves continuing the training of a pre-trained model on your exact dataset, allowing it to adapt to the nuances of your particular application.
5. Train the AI Agent
It’s time to train the machine learning model using your prepared data. This step is where your AI begins to learn from the examples you've provided so it can eventually perform tasks independently. Here are the steps to train your AI agent:
- Set up your environment: Before you start training, set up your machine learning environment. This could involve installing software libraries and frameworks necessary for machine learning.
- Load your data: Import the cleaned and labelled data into your environment for training.
- Split the data: Divide your data into at least two sets: training and testing. The training set will be used to teach your model, and the testing set will be used to evaluate how well your model has learned.
- Choose a model: Initialize the machine learning model you want to train based on this decision.
- Configure training parameters: Set the parameters that will guide the training process. This includes the learning rate, batch size, and number of epochs. The learning rate dictates how much the model adjusts its parameters in response to the observed errors during data processing. The batch size is the number of data samples the model sees before it updates its internal parameters.
Also, the number of epochs representing complete passes through the training dataset affects learning depth. Most epochs provide the model with more opportunities to learn from the data.
- Train the model: Start the training process. The model will use the training data to learn, adjusting its internal parameters to minimize errors.
- Monitor the training process: Track performance metrics such as accuracy or loss during training. These metrics will tell you how well the model is learning. You might need to adjust the training parameters if the model isn’t performing as expected. For example, if the training loss is not decreasing, consider lowering the learning rate.
6. Test and Validate the AI Agent
Developing an AI agent involves testing and validating the system to ensure it performs as expected and meets your goals. This step helps you to identify and fix any issues before the AI agent is fully deployed. Start by running the AI agent through predefined tasks or queries to see how it responds. This is like giving it a mini-exam to see if it learned what it should. Measure how accurately and efficiently the AI agent performs tasks. Check if the responses are correct, how long it takes, and whether the interactions are smooth.
Testing Your AI Agent: Methods and Avoiding Overfitting
Then, you’ll want to choose from the different testing methods:
- Unit testing: Test individual components or parts of the AI agent to ensure each one functions correctly on its own.
- User testing: Invite real users to test the AI agent in controlled settings. This will help you see how the agent performs in real-world scenarios and how users interact with it.
- A/B testing: Compare two versions of the AI agent against each other to determine which one performs better. For instance, test two different response styles or interaction flows to see which is more effective.
Be aware of overfitting and underperformance. Overfitting occurs when an AI agent performs well on the training data but poorly on new, unseen data. To address overfitting, you can use techniques like cross-validation to rotate the data used for training and testing to ensure the model generalizes well.
Continuous Improvement: Fine-Tuning and User Feedback for AI Performance
If the AI agent isn’t performing up to expectations, consider revisiting the training phase to:
- Adjust parameters
- Add more data
- Retrain the model
Set up mechanisms to collect feedback from users, such as:
- Surveys
- Feedback forms
- Direct interviews
Pay attention to what users like and dislike and what they find confusing. Use the feedback to continuously improve the AI agent. This might involve tweaking the conversation flows, training the model with more data, or adjusting the user interface.
7. Deploy and Monitor the AI Agent
It’s time to deploy your AI agent in a live environment and determine how the AI interacts with actual users. Decide where to deploy the AI agent—your website, within a mobile app, or voice-activated platform. Then, integrate the AI agent into your chosen platform. This might involve embedding code into a website, configuring the agent in a mobile app, or setting up the agent with the APIs of a voice platform.
Effective Launch and Ongoing Performance Monitoring for AI Agents
Once integrated, launch the AI agent to start interacting with users. Ensure that all support systems are in place for a smooth launch. Regularly check how well the AI agent is performing.
- Does it understand user queries correctly?
- How is it handling complex conversations?
You can use tools that provide real-time insights into how the AI agent is performing. These tools can show you:
- Response times
- Success rates
- User satisfaction levels
Gathering User Feedback and Error Monitoring for Continuous AI Improvement
You can do this by collecting user feedback directly through the platform. This can be in ratings, comments, or direct survey links after interactions with the AI agent. You can also set up error logging to capture when things go wrong. Get notified if there’s a sudden spike in errors or a drop in performance, allowing for quick action. By deploying the AI agent carefully and setting up monitoring systems, you can ensure that it starts strong and adapts and improves over time, continuing to meet user needs and expectations.
