Investigate How do sequential and pairwise array reductions behave on cancellation-heavy inputs?

Listing reviewed · source terms apply
Datasets

Iris

UCI Machine Learning Repository

Flower measurements for a compact, interpretable multiclass baseline and leakage audit.

Listing reviewed · source terms apply
Original examples

Exact binomial coverage of Wald and Wilson intervals

Executable Science local pilot drafts

Enumerate all binomial outcomes at n=20 and p=0.05, then compare exact interval-coverage calculations with a fixed-seed simulation.

Investigate Do nominal 95% intervals achieve that coverage in this prespecified small-sample setting?

Listing reviewed · source terms apply
Software

Hypothesis

Upstream project repository

Property-based testing tools that generate and simplify test inputs.

Investigate Can a fixed property-based test expose a specified floating-point overclaim within a bounded search protocol?

Methods

3.1. Cross-validation: evaluating estimator performance

scikit-learn documentation

A guide to model-evaluation splits, including grouped and time-series data, nested model selection and permutation-based assessment.

Investigate How much optimism arises when repeated observations from the same group are split across train and test?

Listing reviewed · source terms apply
Software

SciPy

Upstream project repository

Numerical routines for integration, differential equations, optimization, transforms, and statistical analysis.

Investigate Which declared tolerances are attained by adaptive quadrature on a fixed family of endpoint-singular integrals?

Listing reviewed · source terms apply
Methods

1.13. Feature selection

scikit-learn documentation

A guide to variance filters, univariate tests, recursive elimination, model-based selection and selection inside pipelines.

Investigate How much apparent accuracy is introduced by selecting features before cross-validation on noise-only data?

Listing reviewed · source terms apply
Methods

1.16. Probability calibration

scikit-learn documentation

A probability-calibration guide covering reliability curves and sigmoid, isotonic and temperature-scaling approaches.

Investigate How do calibration methods trade off log loss and reliability when the calibration sample is small?

Listing reviewed · source terms apply
Methods

2.7. Novelty and Outlier Detection

scikit-learn documentation

A guide distinguishing outlier detection from novelty detection and comparing assumptions of several anomaly-detection methods.

Investigate How does training-set contamination alter detection rates at a fixed false-positive target?

Listing reviewed · source terms apply
Datasets

2D elastodynamic metamaterials

UCI Machine Learning Repository

Pixelated metamaterial unit-cell designs and band-gap locations and widths for investigating simulation surrogate reliability.

Investigate How does a band-gap surrogate generalize to held-out metamaterial design regions?

Listing reviewed · source terms apply
Methods

3.4. Metrics and scoring: quantifying the quality of predictions

scikit-learn documentation

A broad scoring reference that distinguishes classification, regression, ranking and clustering metrics and their scorer interfaces.

Investigate Can a scoring implementation reproduce independently computed confusion-matrix and probability-loss examples, including undefined edge cases?

Datasets

3W dataset

UCI Machine Learning Repository

Oil-production process signals for studying event detection across operating scenarios.

Investigate How does event detection change when complete wells or production episodes are held out?
