Probabilistic Reasoning

Artificial Intelligence (AI) has established itself as a revolutionary field in computing, defining the future of technology. In its quest to emulate human intelligence, this discipline has developed systems capable of performing complex tasks, opening up endless possibilities. Probabilistic reasoning, as a key subdiscipline, stands out for its ability to model and handle the uncertainty inherent in many decision-making processes.

Machine Learning: The Foundation of AI

Definition and Scope of Machine Learning

Machine Learning (ML) refers to systems that learn and adapt from data, without being explicitly programmed for each task. Its ability to improve with experience makes it a cornerstone of modern AI.

Neural Networks: The Pillar of ML

Neural Networks simulate the information processing of the human brain. These data structures, formed by interconnected nodes (artificial neurons), are fundamental for pattern learning and decision making.

Types of Neural Networks

Deep Neural Networks (DNNs): Learn complex patterns, being crucial in fields like language processing and computer vision.
Convolutional Neural Networks (CNNs): Specialized in multidimensional data, they excel at tasks such as image classification.
Recurrent Neural Networks (RNNs): Suitable for processing data sequences, they are fundamental in time series prediction and language processing.
Generative Neural Networks (GANs): Create artificial data, consisting of two parts: a generative and a discriminative one.

Complementary Techniques in ML

Finite State Machines (FSM): Used to control devices or processes through a set of states and transitions.
Genetic Algorithms (GA): Seek optimal solutions using genetic operators.
Reinforcement Learning (RL): Trains agents to make optimal decisions in an environment, based on rewards and punishments.
