Results for "true negative rate"

14 results

ROC Curve Intermediate

Plots true positive rate vs false positive rate across thresholds; summarizes separability.

Foundations & Theory
Learning Rate Schedule Intermediate

Adjusting learning rate over training to improve convergence.

AI Economics & Strategy
Gradient Descent Intermediate

Iterative method that updates parameters in the direction of negative gradient to minimize loss.

Optimization
Perplexity Intermediate

Exponential of average negative log-likelihood; lower means better predictive fit, not necessarily better utility.

Evaluation & Benchmarking
Recall Intermediate

Of true positives, the fraction correctly identified; sensitive to false negatives.

Foundations & Theory
Specificity Intermediate

Of true negatives, the fraction correctly identified.

Foundations & Theory
Calibration Intermediate

The degree to which predicted probabilities match true frequencies (e.g., 0.8 means ~80% correct).

Foundations & Theory
Cross-Entropy Intermediate

Measures divergence between true and predicted probability distributions.

AI Economics & Strategy
Warmup Intermediate

Gradually increasing learning rate at training start to avoid divergence.

AI Economics & Strategy
Overconfidence Intermediate

Probabilities do not reflect true correctness.

Model Failure Modes
Throughput Ceiling Intermediate

Maximum system processing rate.

AI Economics & Strategy
Takeoff Speed Advanced

Rate at which AI capabilities improve.

AI Safety & Alignment
False Negative Intermediate

Failure to detect present disease.

AI in Healthcare
Learning Rate Intermediate

Controls the size of parameter updates; too high diverges, too low trains slowly or gets stuck.
