Probabilistic inference is the process of deriving the likelihood of certain outcomes or hypotheses based on known probabilities and observed data, often using Bayesian methods. It is fundamental in fields like machine learning and statistics, enabling predictions and decision-making under uncertainty.

likelihood of certain outcomes

A hypothesis is a testable statement that predicts a possible explanation to a scientific question or problem. It serves as a foundational element in the scientific method, guiding experimentation and observation to validate or refute its claims.

known probabilities

Observed data refers to information collected through direct measurement or observation of a phenomenon, often used as the foundation for statistical analysis and empirical research. It is crucial for validating hypotheses and building models that reflect real-world conditions and behaviors.

Bayesian methods provide a probabilistic framework for updating beliefs in the presence of new data, using Bayes' theorem as the core principle. These methods are particularly powerful for incorporating prior knowledge and handling uncertainty in complex models, making them widely applicable in fields like statistics, machine learning, and data science.

Bayesian methods

Machine learning is a subset of artificial intelligence that involves the use of algorithms and statistical models to enable computers to improve their performance on a task through experience. It leverages data to train models that can make predictions or decisions without being explicitly programmed for specific tasks.

Statistics is the science of collecting, analyzing, interpreting, presenting, and organizing data to make informed decisions and predictions. It provides the tools to handle variability and uncertainty in data, enabling researchers and analysts to draw valid conclusions and insights from empirical evidence.

Decision-making under uncertainty involves choosing actions based on incomplete information and unpredictable outcomes, often requiring probabilistic reasoning and risk assessment. It is crucial in fields like economics, management, and artificial intelligence, where decisions must account for variability and unknowns to optimize results.
