Summary of "Aula 01 - INTELIGÊNCIA ARTIFICIAL"
Main Ideas and Concepts:
- Definition of Artificial Intelligence (AI):
AI is the field of study focused on creating computational systems that perform tasks requiring human intelligence, such as image recognition, Natural Language Processing, and decision-making.
- Historical Context:
The development of AI is closely linked to the evolution of computing, beginning with the creation of the first digital computer in 1941. Key milestones include:
- 1943: Introduction of artificial neurons, laying the groundwork for Neural Networks.
- 1956: The term "Artificial Intelligence" was coined at the first official AI Conference.
- 1960s: Development of early AI programs that could simulate human communication and decision-making.
- 1970s: Formalization of theories and mathematical foundations for AI.
- 1980s: Global investments in AI, particularly in Japan and the USA.
- 1990s: Transition of AI from academia to practical applications in various industries.
- Interdisciplinary Nature of AI:
AI draws from multiple fields, including psychology, linguistics, philosophy, and computer science, to simulate human-like functions.
- Knowledge Representation:
AI systems need to represent knowledge effectively to process and solve complex problems, involving identification of objects, properties, categories, and events.
- Natural Language Processing (NLP):
NLP is essential for AI to understand and interact using human language, which is often imperfect and ambiguous. Components of NLP include:
- Lexical analysis (word identification)
- Syntactic analysis (sentence structure)
- Semantic analysis (meaning of sentences)
- Pragmatic analysis (context interpretation)
- Creativity and Problem Solving in AI:
AI must demonstrate creativity by generating innovative and relevant responses, rejecting outdated problem-solving methods, and maintaining persistence in achieving goals. Problem-solving involves formulating problems, defining objectives, and exploring possible solutions using Search Strategies.
- Search Strategies in AI:
Different Search Strategies include:
- Blind Search: Systematic exploration without prior knowledge of the best node to expand.
- Breadth-First Search: Expands the shallowest unexplored node.
- Depth-First Search: Expands the deepest unexplored node.
- Iterative Deepening Search: Combines the benefits of breadth and depth-first searches, ideal for large search spaces.
- Performance Evaluation:
Criteria for evaluating Search Strategies include completeness, time complexity, space complexity, and optimization of the solution.
Methodology and Key Points:
- Understanding AI's Role: Recognize AI's integration into daily life (e.g., recommendations, voice assistants).
- Key Historical Milestones: Familiarize with significant developments in AI history from the 1940s to the 1990s.
- Interdisciplinary Approach: Acknowledge the various fields contributing to AI's evolution.
- NLP Components: Understand the layers of Natural Language Processing essential for AI communication.
- Creativity in AI: Identify characteristics of Creativity in AI systems.
- Problem Solving and Search Strategies: Learn about different Search Strategies and their applications in AI problem-solving.

— 30:40 — « PLN natural language processing is the ability of an Artificial Intelligence system to interact with humans using human language. »
— 31:44 — « The four characteristics that indicate a creative solution are the use of existing elements in an innovative and relevant way. »
— 32:01 — « There's no point in me talking to her about a ship and she talking to me about a boy. She has to understand what I'm saying. »
— 32:32 — « It has to reach the objective she has to get as far as she proposed at the beginning of the problem. »
— 33:31 — « Non-computable problems are those that cannot be solved by such procedures and require the search for solutions through strategies that explore different possibilities typical of real-world problems. »
