dubicube vs fastml: at a glance
What is dubicube?
dubicube grew from a bootstrap helper into the uncertainty layer other B-Cubed packages call.
dubicube supplies bootstrapping and confidence-interval machinery for biodiversity data cubes in the B-Cubed project. The 0.10–0.12 series added the things a library needs to be depended on rather than copied: automatic detection of group-specific versus whole-cube bootstrapping, an optional boot backend, and then a second capability area in 0.12.0 with data quality diagnostics and cube filtering. The sibling indicator package b3gbi now delegates its confidence intervals here.
What is fastml?
fastml added survival modelling and leakage-proof resampling, moving past classification and regression.
A tidymodels-based AutoML wrapper that trains, tunes and compares many engines from one call. The 0.6.x line added engine-specific tuning parameters, class-imbalance handling, early stopping and DALEX-based explainability. The 0.7.5 release is far larger: a full survival analysis task with its own engines, MICE imputation and integrated Brier scoring, plus unbiased nested cross-validation, grouped, blocked and rolling resampling helpers, fold-wise imputation, recipe leakage checks, and a sandbox for user-supplied preprocessing.

dubicube grew from a bootstrap helper into the uncertainty layer other B-Cubed packages call.
◆ Current state
dubicube supplies bootstrapping and confidence-interval machinery for biodiversity data cubes in the B-Cubed project. The 0.10–0.12 series added the things a library needs to be depended on rather than copied: automatic detection of group-specific versus whole-cube bootstrapping, an optional boot backend, and then a second capability area in 0.12.0 with data quality diagnostics and cube filtering. The sibling indicator package b3gbi now delegates its confidence intervals here.
◆ Where it's heading
Release notes are terse — usually one line and an issue number — but the direction is legible in what gets automated. Decisions the caller used to make explicitly are being inferred: resampling scope in 0.10.0, the no-bias option in 0.11.0, and process_cube_args threaded through filter_cube() so the filtering path matches cube processing. The diagnostics work in 0.12.x is the newer line, and 0.12.2's rename of the heatmap option to rule suggests that surface is still settling.
◆ Prediction
The diagnostics and filtering additions have needed a follow-up fix in each of the two releases since they landed, so the next release is most likely more consolidation there rather than a new capability area.
fastml
0.0ANALYTICS
fastml added survival modelling and leakage-proof resampling, moving past classification and regression.
◆ Current state
A tidymodels-based AutoML wrapper that trains, tunes and compares many engines from one call. The 0.6.x line added engine-specific tuning parameters, class-imbalance handling, early stopping and DALEX-based explainability. The 0.7.5 release is far larger: a full survival analysis task with its own engines, MICE imputation and integrated Brier scoring, plus unbiased nested cross-validation, grouped, blocked and rolling resampling helpers, fold-wise imputation, recipe leakage checks, and a sandbox for user-supplied preprocessing.
◆ Where it's heading
The package is moving from convenience wrapper to something that has to be defensible statistically. Nested cross-validation, fold-wise rather than up-front imputation, and explicit leakage checks are all corrections to the shortcuts that make AutoML easy and its scores optimistic. Survival adds a third task type alongside classification and regression, and it arrived with its own metrics rather than being bolted onto the existing ones. Note the entry body is cut off at 8,000 characters, so the release is larger than what is shown.
◆ Prediction
Expect the remaining survival engines to fill in and the sandboxing of custom preprocessing to tighten, since both were still being iterated on within this same release's commit list.
