MOABB interface to tombolo for analysis of ML benchmarks

moabbr

MOABB interface to tombolo for analysis of machine learning benchmarks in R.

MOABB evaluation results are a pandas DataFrame with one row per pipeline/dataset/subject/session. moabbr transforms evaluation results, then calls tombolo to run the analysis. Each dataset is treated as an independent study and each pipeline as a treatment.

Requirements

Docker must be installed and running, and the tombolo image must be pulled:

docker pull ethandavisecd/tombolo:latest

Installation

pip install moabbr

Usage

results is the pd.DataFrame returned by a MOABB evaluation, with columns dataset, pipeline, subject, and score.

from moabbr import nma, bnma

result = nma(results)    # frequentist NMA via netmeta
result = bnma(results)   # Bayesian NMA via gemtc

Both functions accept a greater_is_better flag (default True). Set to False for metrics where lower is better (e.g. error rate).

Plots

from moabbr.plots import (
    ranking_plot,
    league_table,
    forest_plot,
    heterogeneity_table,
    prediction_table,  # nma only
    convergence_table, # bnma only
)

ranking_plot(result)
league_table(result)
forest_plot(result, reference="my_pipeline")
heterogeneity_table(result)

Each function returns a matplotlib.figure.Figure.
