A side-by-side editorial comparison of aniread and e2tree — release velocity, themes, recent moves, and the top alternatives to consider.
aniread keeps finding that every tracker lies about coordinates in its own way.
aniread is the reader package of the animovement suite, importing output from pose-estimation and centroid trackers into aniframe objects. The 0.4.0 release standardised something every reader had been getting differently — source data using an image top-left origin is now reflected into a conventional bottom-left origin, across eleven readers. Since then the work has been Octron and BORIS specifics, and 0.5.0 extended the package past tracking data into behavioural events.
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.

Each release reads as a catalogue of the ways a source format is imprecise: Octron omitting frames where nothing was detected, BORIS exports whose image index puts a STOP before its START, idtracker.ai renaming its leading column, Windows UNC shares reporting a false negative on read permission. The fixes share a posture of reconstructing what the format left implicit rather than passing the gap through — reinstating missing frames as all-NA rows, recovering a frame interval from time and FPS. Format support now tracks aniframe's class work closely, with 0.5.0 requiring aniframe 0.6.0 for the anievent class it produces.
get_supported_sources() was added so downstream packages can discover formats programmatically instead of hard-coding them, which suggests the next additions are more sources behind that registry rather than changes to the reader API.
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.
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.
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.
