Artificial Intelligence (AI) is having a profound impact on the direction of business and society as a whole. Its ability to create autonomous systems capable of performing complex tasks is redefining the limits of what was previously thought impossible. And the best news is that building an AI system is no longer an intimidating or expert-only process, but is within the reach of many.

From AIs writing articles about themselves to AIs winning art competitions, the limits of autonomous systems are being challenged and expanded every day. This inspiring scenario makes many people curious about how to build their own AI systems and wonder if this complex technology is within the reach of ordinary people.

The answer is yes! While building an AI system from scratch can be a complex challenge requiring advanced technical expertise, there are several tools available to facilitate the process. Both commercial and open-source solutions offer user-friendly features and interfaces that allow beginners, even those with no prior programming experience, to take their first steps into the fascinating world of AI.

This article serves as a practical guide to the process of building an AI system, opening the door for you to explore the fascinating world of AI system with complete confidence. Prepare to embark on a journey of learning and discovery where you can master the basics of AI system.

Programming Languages and AI

Before we dive into the stages of building an AI system, it’s important to understand the programming languages that are best suited for the job. While any robust language can be used, some stand out in the context of AI, here are a few:


This general-purpose language is a popular choice because of its readability and the wide variety of libraries available. Python is particularly well suited to AI, with frameworks such as PyTorch simplifying the development process. But what makes Python so great for AI?

  • Simplicity and readability: Python’s intuitive syntax makes it easy to learn and write code, even for beginners. This allows you to focus on AI concepts rather than the complexities of the language.
  • Versatility: Python is a general-purpose language, which means it can be used for a wide range of tasks, from data analysis and web development to, of course, AI. This versatility makes it a valuable tool for any professional in the field.
  • Rich libraries and tools: The Python universe offers a vast set of AI-specific libraries and frameworks such as NumPy, Pandas, TensorFlow, and PyTorch. These tools facilitate the development of machine learning, natural language processing, and computer vision models, accelerating your development process.
  • Vibrant community: The Python community is extremely active and engaged, with numerous online forums, tutorials, and support groups to help beginners and experts alike. This community ensures that you will always have access to valuable help and resources on your learning journey.


A newer language, Julia was designed specifically for scientific computing and data analysis. Its streamlined syntax and impressive performance make it an attractive option for AI projects.

  • Less syntactic complexity: Compared to languages like Java or C++, Julia presents a more intuitive and less complex syntax, making it easier for beginners to learn and write code.
  • Superior performance: Julia excels in processing speed, outperforming languages like Python or R, making it ideal for efficiently handling large datasets and complex algorithms.
  • Designed for data science: Unlike other general-purpose languages, Julia was designed specifically to meet the needs of data science. This means it has native features and functionality that make it easy to work with data, from collection and preprocessing to analysis and visualization.


Although it has been eclipsed in popularity by Python, R remains a solid choice, especially for statistical tasks and data analysis. Its large collection of packages makes it a valuable tool for data scientists. Although its syntax can be challenging for beginners, R offers a vast universe of libraries that specialize in various areas of data science, such as

  • Statistical analysis: A complete set of tools for performing complex statistical analysis, from hypothesis testing to linear regression and nonlinear modeling.
  • Data Processing: Robust libraries for manipulating, cleaning, and preparing large data sets for analysis.
  • Data Visualization: Powerful tools for creating meaningful graphs and visualizations that help you understand your data.

What are the steps in building an AI system?

The importance of the AI system is symbolized by an image of AI in a human hand.

Now that we understand the tools at our disposal, let’s dive into the practical steps of building an AI system.

1. Set a goal

Before you start writing code, it’s important to clearly define the problem your AI system will solve. The more precise your goal, the more effective your solution will be. Determine the value proposition of your product and why investing in it is a smart decision.

2. Collect and clean data

As the saying goes, “garbage gets in, garbage gets out.” Data quality is critical to the success of an AI project. Make sure you collect relevant, unbiased data and spend time cleaning and organizing it. In the AI universe, data can be divided into two main types: Structured data, which is organized in a defined format, such as spreadsheets, relational databases, or CSV files. Unstructured data is not organized in a formal format, such as free text, images, audio, or video. What makes data “right” for AI?

  • Relevance: The data must be directly related to the problem the AI model is trying to solve. This means that the data must contain the necessary information for the model to learn and make accurate predictions.
  • Adequacy: The amount of data should be sufficient to adequately represent all variables and nuances of the problem. A trained model with insufficient data can lead to incorrect generalizations and inaccurate results.
  • Impartiality: Data should not contain biases or distortions that could lead the AI model to make unfair or discriminatory decisions. It is critical to ensure that data is collected and pre-processed impartially to avoid algorithmic bias.

3. Create the algorithm

There are several techniques and algorithms available for building an AI system, from deep neural networks to supervised learning algorithms. Choose the most appropriate one for your problem and start developing it. 

  • Neural Networks and Deep Learning: Inspired by the workings of the human brain, artificial neural networks excel at complex machine learning tasks such as image recognition, natural language processing, and time series prediction. Deep learning, a subset of artificial intelligence, uses multi-layer artificial neural networks to achieve even more impressive levels of performance.
  • Random Forests: Ideal for classification and regression tasks, Random Forests combine multiple decision models in a single algorithm, increasing the robustness and reliability of predictions.
  • K-Nearest Neighbors (KNN): A simple and intuitive algorithm, KNN relies on comparing new data with known data points to make classifications or predictions.
  • Symbolic regression: This approach uses mathematical models to represent the relationships between the variables of the problem, allowing for a better understanding of the data and identification of relevant patterns.

4. Training the algorithm

Training is a critical part of the AI development process. Using a portion of your data to train the algorithm allows it to recognize patterns and make accurate predictions. Training an AI algorithm involves presenting the algorithm with a set of pre-processed data.

By analyzing the data, the algorithm identifies patterns, relationships, and rules that highlight the problem. This information is used to adjust the algorithm’s parameters so that it can make accurate predictions and generalize the knowledge it has gained to new data. In practice, most data scientists use a technique called data partitioning to ensure the robustness and reliability of the training. In this technique, the entire data set is divided into two parts:

  • Training Set (80%): This part, which consists of most of the data, is used to train the algorithm and adjust its parameters.
  • Test Set (20%): This part, reserved for evaluation, is used to test the performance of the algorithm on data that it did not see during training.

5. Implementation of the final product

With the algorithm trained, it’s time to prepare the final product for launch. Develop a user-friendly interface and finalize the details before making it available for use.
