Welcome to the first post of our series on Artificial Intelligence (AI). Today we will explore the basic concepts of AI, the difference between AI, machine learning, and deep learning, and some examples of everyday applications. We will also look at the state of AI in Portugal. The goal is to introduce you to AI and its importance in today’s world.
What is Artificial Intelligence?
Artificial Intelligence, or AI, is a branch of computer science dedicated to creating systems capable of performing tasks that typically require human intelligence. This includes skills such as learning, pattern recognition, decision making, and problem-solving. AI attempts to mimic human cognitive processes so that machines can perform tasks autonomously and efficiently.
Brief History of AI
The idea of intelligent machines has existed for centuries, but AI as we know it began to develop in the 1950s. Here are some important milestones in the history of AI:
- 1950: Alan Turing proposes the “Turing Test” to evaluate machine intelligence.
- 1956: The term “Artificial Intelligence” is coined at the Dartmouth Conference, marking the official birth of the field.
- 1966: ELIZA, one of the first AI programs, simulates a human therapist.
- 1997: Deep Blue, an IBM computer, defeats world chess champion Garry Kasparov.
- 2011: Watson, another IBM system, wins the Jeopardy! quiz show.
- 2016: AlphaGo, by DeepMind, defeats the world champion of Go, a game considered more complex than chess.
Basic Concepts
AI vs. Machine Learning vs. Deep Learning
- Artificial Intelligence (AI): A broad field encompassing any technique that allows a machine to mimic human intelligent behavior.
- Machine Learning: A subfield of AI that uses algorithms to analyze data, learn from it, and make predictions or decisions without being explicitly programmed.
- Deep Learning: A subfield of machine learning that uses artificial neural networks with many layers (deep neural networks) to model complex patterns in large volumes of data.
Everyday Applications Examples
AI is present in many aspects of our daily lives. Here are some examples:
- Virtual Assistants: Siri, Alexa, and Google Assistant use AI to understand voice commands and perform tasks.
- Content Recommendations: Platforms like Netflix, Spotify, and YouTube use AI to recommend movies, music, and videos based on user preferences.
- Image and Video Recognition: Facebook uses AI to recognize and tag faces in photos. YouTube uses AI to identify and remove inappropriate content.
- Autonomous Cars: Companies like Tesla and Waymo are developing vehicles that can drive themselves using sensors and AI algorithms.
- Healthcare: AI is used to diagnose diseases, predict epidemic outbreaks, and even develop new medications.
The State of AI in Portugal
Portugal is making significant strides in adopting and developing AI, both in the public and private sectors. Here are some highlights:
Initiatives and Development
- National Plans: Portugal launched the National Initiative for Digital Skills (INCoDe.2030), which includes promoting AI as one of its priorities. This initiative aims to improve the digital skills of the population and encourage technological innovation.
- Investment and Startups: The country has seen a significant increase in the number of startups focused on AI. Companies like Feedzai (specializing in fraud prevention) and Unbabel (which uses AI for translation) are examples of international success.
- Education and Research: Portuguese universities, such as Instituto Superior Técnico (IST) and the University of Porto, are leading AI research. Additionally, AI courses and training are becoming increasingly common, preparing the next generation of specialists.
Comparison with Europe and the World
- Competitiveness: Although Portugal is not yet at the level of major European countries in terms of AI investment, such as Germany, France, and the United Kingdom, it is making rapid progress. Collaboration with other European countries and participation in EU-funded research projects are helping to accelerate this development.
- Adaptation and Implementation: Compared to many countries, Portugal has shown a good ability to adapt and implement AI technologies. Portuguese companies are adopting AI solutions to improve operational efficiency and offer better services to customers.
Examples of Portuguese Projects
- Feedzai: A company that uses AI to detect and prevent fraud in financial transactions. Feedzai has clients worldwide and is an example of how Portugal can compete on the global stage.
- Unbabel: Combines artificial intelligence with human translation to offer high-quality translation services. The company has attracted international investors and is rapidly expanding.
- Academic Projects: Universities in Portugal are involved in various AI research projects, from robotics to big data analysis, often collaborating with companies and international institutions.
The Importance of AI
AI is transforming virtually every industry. Here are some reasons why AI is so important:
- Efficiency: Automates repetitive tasks and quickly analyzes large volumes of data.
- Innovation: Opens up new possibilities in areas such as healthcare, transportation, education, and entertainment.
- Precision: Can outperform humans in tasks that require precision, such as medical diagnostics or weather forecasting.
- Personalization: Enables the customization of products and services at scale, improving user experience.
