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.

What is fluxnet-package?

fluxnet keeps swapping its own plumbing — first a Python downloader, now a DuckDB backend.

fluxnet gives R users access to FLUXNET eddy covariance data: listing sites, downloading, quality control and citation. Two releases in three months replaced the parts underneath the user-facing functions — 0.3.0 moved downloading off httr2 onto the fluxnet_shuttle Python library, and 0.6.0 added experimental DuckDB ingest so data can be queried with dplyr without being read into memory. The API around them has been churning in step, with site_ids='all' deprecated and max_gapfill renamed to threshold.

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.

F0.0

fluxnet keeps swapping its own plumbing — first a Python downloader, now a DuckDB backend.

◆ Current state

fluxnet gives R users access to FLUXNET eddy covariance data: listing sites, downloading, quality control and citation. Two releases in three months replaced the parts underneath the user-facing functions — 0.3.0 moved downloading off httr2 onto the fluxnet_shuttle Python library, and 0.6.0 added experimental DuckDB ingest so data can be queried with dplyr without being read into memory. The API around them has been churning in step, with site_ids='all' deprecated and max_gapfill renamed to threshold.

◆ Where it's heading

The direction is toward handling data volumes that do not fit the read-it-all-into-R model, and toward borrowing rather than reimplementing — a Python library for transfers, DuckDB for storage. That comes with dependency weight the package now has to manage itself, which is what flux_install_shuttle() and its virtualenv handling exist for. Renames and deprecations in nearly every release suggest the interface is being fixed as the backend settles rather than the other way around.

◆ Prediction

The DuckDB functions are marked experimental and cover connect, build and update only, so the next step is most likely stabilising them and routing the existing quality-control and extraction functions through the database rather than around it.
