Results for "uncertainty measure"

43 results

Entropy Intermediate

A measure of randomness or uncertainty in a probability distribution.

AI Economics & Strategy
Inter-Annotator Agreement Intermediate

Measure of consistency across labelers; low agreement indicates ambiguous tasks or poor guidelines.

Foundations & Theory
Active Learning Intermediate

Selecting the most informative samples to label (e.g., uncertainty sampling) to reduce labeling cost.

Foundations & Theory
Rademacher Complexity Intermediate

Measures a model’s ability to fit random noise; used to bound generalization error.

AI Economics & Strategy
Information Gain Intermediate

Reduction in uncertainty achieved by observing a variable; used in decision trees and active learning.

AI Economics & Strategy
Mutual Information Intermediate

Quantifies shared information between random variables.

AI Economics & Strategy
Fisher Information Intermediate

Measures how much information an observable random variable carries about unknown parameters.

AI Economics & Strategy
Variance Advanced

Measure of spread around the mean.

Probability & Statistics
Stochastic Approximation Intermediate

Optimization under uncertainty.

Foundations & Theory
Objective Function Intermediate

A scalar measure optimized during training, typically expected loss over data, sometimes with regularization terms.

Optimization
Generalization Intermediate

How well a model performs on new data drawn from the same (or similar) distribution as training.

Foundations & Theory
Next-Token Prediction Intermediate

Training objective where the model predicts the next token given previous tokens (causal modeling).

Foundations & Theory
Reproducibility Intermediate

Ability to replicate results given same code/data; harder in distributed training and nondeterministic ops.

Foundations & Theory
VC Dimension Intermediate

A measure of a model class’s expressive capacity based on its ability to shatter datasets.

AI Economics & Strategy
Cross-Entropy Intermediate

Measures divergence between true and predicted probability distributions.

AI Economics & Strategy
