UCI Machine Learning Repository
Generated card hands with rule-based labels for testing rare combinatorial classes.
Investigate Can a poker-hand classifier identify rare hand classes on a split that excludes reordered duplicates?
Upstream project repository
Columnar DataFrame processing with query planning and parallel execution.
Investigate Do eager and lazy query plans preserve exact grouped totals under filtering and null values?
Upstream project repository
Management and retrieval of data files with registry and checksum support.
Investigate Does a fixed registry detect a deliberately changed input rather than silently accepting stale bytes?
UCI Machine Learning Repository
City electricity-demand measurements for studying seasonal and multi-zone forecasts.
Investigate Does a zone-aware load forecast improve on seasonal persistence in a chronological Tetouan holdout?
UCI Machine Learning Repository
Artificial oscillatory sequences for testing methods against controlled temporal structure.
Investigate Can a period-aware baseline outperform persistence on a fixed pseudo-periodic holdout?
Upstream project repository
Python support for the OPeNDAP data-access protocol.
Investigate Do fixed constraint expressions select the expected cells from a tiny synthetic dataset?

Upstream project repository
Python bindings for coordinate transformations and geodetic calculations in PROJ.
Investigate Does a fixed coordinate transformation preserve the declared axis convention and a prespecified round-trip tolerance?
Upstream project repository
Discrete and continuous wavelet transforms for numerical signal analysis.
Investigate How do boundary modes affect reconstruction and coefficient interpretation for short synthetic signals?
UCI Machine Learning Repository
Chemical descriptors and aquatic bioassay outcomes for a bounded ecotoxicology regression audit.
Investigate Which compounds dominate aquatic-toxicity error after train-only preprocessing and influence analysis?
UCI Machine Learning Repository
Molecular descriptors and biodegradation labels for checking chemical prediction protocols.
Investigate How does chemical-group-aware splitting change biodegradation classification performance?
UCI Machine Learning Repository
Chemical descriptors and fish bioconcentration factors for studying environmental-property prediction.
Investigate How does bioconcentration prediction change when related chemicals are kept in the same fold?
