Definition of artificial intelligence
What is artificial intelligence?
Artificial intelligence refers to the ability of machines to perform tasks that, when carried out by humans, require intelligence. This includes activities such as learning, understanding natural language, image recognition, and decision-making.
AI makes it possible to artificially improve how machines interact with their environment, aiming to predict and respond appropriately to various situations.
If you want a quick understanding of what AI is, we’ve written a complete article on the simple definition of artificial intelligence.
Narrow AI vs. strong AI
Narrow (or weak) AI is designed to perform a specific task, such as facial recognition or movie recommendations. By contrast, strong (or general) AI would be able to understand, learn, and apply its skills broadly, similar to a human being, with intelligence comparable to ours.

Timelessly, how can we talk about AI without mentioning science fiction? In science fiction, artificial intelligence systems have often been imagined as entities with critical intelligence, able to predict future events and classify information with remarkable accuracy.
Today, learning algorithms—such as those used to develop self-driving cars—use deep neural networks and learning techniques to achieve intelligence in a more sophisticated way.

These systems, often powered by an artificial data source, rely on hidden layers and vectors to optimize performance. The gradient, along with linear and non-linear approaches, plays a crucial role in the learning process, enabling automated systems to build accurate predictive models and adapt to complex environments.
AI techniques and technologies
Machine learning algorithms
Machine learning relies on algorithms that can learn from data. The main types of learning are supervised learning, unsupervised learning, and reinforcement learning. These learning algorithms form the foundation of intelligence in modern systems.
Supervised learning vs. unsupervised learning
- Supervised Learning: Algorithms learn from labeled examples, meaning each data input is associated with a correct output.
- Unsupervised Learning: Algorithms look for patterns in data without prior labels. This type of learning is often used for data analysis and discovering new insights.
Deep learning and neural networks
Deep learning uses deep neural networks to model complex relationships in data. These networks are made up of successive layers of artificial neurons, each adjusting its parameters to reduce prediction error. These networks, or deep networks, are at the heart of many modern AI applications.

How AI systems based on deep networks and advanced algorithms work
Modern artificial intelligence systems, especially those using deep networks, have become AI engines capable of predicting outcomes with high accuracy.
These artificial systems rely on sophisticated learning algorithms that allow an intelligent machine to improve over time. For example, a recognition algorithm can analyze labeled datasets to learn how to identify images or texts autonomously.
The algorithms used for these tasks often rely on neural networks, where each neuron plays a key role in the learning process.
An intelligent algorithm
An intelligent algorithm designed to filter spam uses powerful algorithms to detect unwanted messages by relying on past data. In an artificial setting, these AI algorithms can be integrated into decision-support systems to provide predictive recommendations.
