Aleatoric Uncertainty

Aleatoric uncertainty refers to the inherent variability in a system or process that cannot be reduced.

Anomaly Detection

AD

Anomaly Detection is the identification of patterns in data that do not conform to expected behavior.

Approximation error

AE

Approximation error measures the difference between an estimated value and the actual value.

Autocovariance

Autocovariance measures how a variable correlates with itself over time, indicating its internal structure and dependencies.

Autoregressive

AR

Autoregressive refers to a type of model that predicts future values based on past values in a time series.

Bartlett’s Test

Bartlett's Test assesses the equality of variances across multiple groups in statistics.

Bayesian Deep Learning

BDL

Bayesian Deep Learning combines deep learning with Bayesian inference for improved uncertainty estimation in predictions.

Bayesian Network

BN

A Bayesian Network is a graphical model representing probabilistic relationships among variables.

Bayesian Optimization

BO

Bayesian Optimization is a probabilistic model-based approach for optimizing complex functions.

Bayesian programming

BP

Bayesian programming is a statistical approach to programming that applies Bayes' theorem for decision-making and predictions.

Bias Term

BT

A bias term is an additional parameter in machine learning models that helps adjust predictions.

Bootstrap Sampling

BS

Bootstrap Sampling is a statistical technique for estimating the distribution of a sample statistic by resampling with replacement.

Calibration Plot

A calibration plot visually assesses the performance of a predictive model by comparing predicted probabilities to actual outcomes.

Causal Inference

Causal inference is a method to determine cause-and-effect relationships from data.

Causal Reasoning

CR

Causal reasoning is the process of identifying cause-and-effect relationships between events or phenomena.

Causal Tracing

CT

Causal tracing is a method used to identify and analyze cause-and-effect relationships in data or systems.

Central Limit Theorem

CLT

The Central Limit Theorem states that the distribution of sample means approaches a normal distribution as sample size increases.

Chi-Square Distribution

χ²

The Chi-Square Distribution is a statistical distribution used to assess the goodness of fit of observed data to expected data.

Class Imbalance

CI

Class imbalance occurs when the classes in a dataset are not represented equally, affecting model performance.

Combinatorial Bandit

CB

A combinatorial bandit is a type of algorithm that helps make decisions when multiple options are available simultaneously.

Computational statistics

CompStat

Computational statistics involves using computer algorithms to analyze and interpret statistical data.

Conditional Probability

Conditional probability measures the likelihood of an event given that another event has occurred.

Confidence Bounds

Confidence bounds are statistical limits that quantify uncertainty in predictions or estimates.

Confidence Interval

CI

A confidence interval estimates a range of values likely to contain a population parameter, reflecting uncertainty in measurements.

Contingency Table

A contingency table displays the frequency distribution of variables and helps analyze relationships between them.

Continuous Variable

A continuous variable is a type of quantitative data that can take any value within a given range.

Correlation Coefficient

r

A statistical measure that describes the strength and direction of a relationship between two variables.

Correlation Matrix

A correlation matrix displays the correlation coefficients between multiple variables in a dataset.
