dubicube vs e2tree
A side-by-side editorial comparison of dubicube and e2tree — release velocity, themes, recent moves, and the top alternatives to consider.
dubicube vs e2tree: 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 e2tree?
The explainable-ensemble-tree package now measures whether its own explanations are faithful.
e2tree builds a single interpretable tree that approximates a fitted ensemble, working from the proximity structure the ensemble induces between observations. The 1.0.0 release added the piece that had been missing: a Goodness of Interpretability index quantifying how well the approximating tree reconstructs the ensemble's own proximity matrix, with a permutation test for significance. Interactive visualisation and a C++ backend with OpenMP parallelism arrived alongside, and support now spans ranger and CatBoost as well as the original targets.

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.
e2tree
0.0ANALYTICS
The explainable-ensemble-tree package now measures whether its own explanations are faithful.
◆ Current state
e2tree builds a single interpretable tree that approximates a fitted ensemble, working from the proximity structure the ensemble induces between observations. The 1.0.0 release added the piece that had been missing: a Goodness of Interpretability index quantifying how well the approximating tree reconstructs the ensemble's own proximity matrix, with a permutation test for significance. Interactive visualisation and a C++ backend with OpenMP parallelism arrived alongside, and support now spans ranger and CatBoost as well as the original targets.
◆ Where it's heading
Development has moved from producing an explanation to defending it. The GoI index and its permutation test change the package's claim from here is a tree that resembles your ensemble to here is how closely it resembles it and whether that could have happened by chance — the question a reviewer asks of any surrogate model. Around that, the work is engineering: the proximity matrix construction moved from R-level parallel loops into C++ with thread-level parallelism, and recent releases have been absorbing the awkwardness of supporting multiple ensemble backends, where a multi-class CatBoost objective returns a score matrix where a vector was expected. Interactive visNetwork output and standalone HTML export point at explanations meant to be shared rather than only inspected.
◆ Prediction
Given how much recent effort has gone into per-backend adapters, expect further work on ensemble compatibility; the entries do not indicate whether the interpretability index is heading toward comparing surrogate trees against each other.
