v0.5.0

BetaML v0.5.0

Diff since v0.4.1

What’s new in v0.5 (compared to 0.4.1):

Documentation

• Extensive step-by-step tutorial to BetaML algorithms (and in a certain sense to ML and Julia in general), with comparisons with Clustering.jl, GaussianMixtures.jl, Flux.jl and DecisionTree.jl packages;
• Added option to "preview" the documentation without running the code in the tutorial (push!(ARGS,"preview"); include("make.jl"))

MLJ API

• Integration with the MLJ API. The following models have been made available to the MLJ framework : PerceptronClassifier, KernelPerceptronClassifier, PegasosClassifier, DecisionTreeClassifier, DecisionTreeRegressor, RandomForestClassifier, RandomForestRegressor, KMeans, KMedoids, GMMClusterer, MissingImputator

Package reorganisation

• All the functionality of the different sub-modules is now re-exported at the root level, so the user needs just to using BetaML to access it
• The Utils module has been split in different files

Stochasticity management

• Added the parameter rng to all stochastic models to allow fine-tuning of the stochasticity/replicability trade-off
• Added function generateParallelRngs to allow repeteable results indipendently from the number of thread used
• Extended Random.shuffle function to allow multiple matrices and specify the dimension over which to shuffle

Utilities (BetaML.Utils)

• Added dims and copy parameters to partition
• Added crossValidation, with a user defined function/do block and configurable sampler (SamplerWithData{T <: AbstractDataSampler})
• Added ConfusionMatrix
• Added the pool1d activation function

Other

• Improved the grid initialisation for clusters
• Updated the JOSS paper
• New package dependencies: StableRNGs and ForceImport
• Several bugfixes, optimisations and updated dependencies (see the commit log for details)

Closed issues:

• Avoid observation-by-observation construction of UnivariateFinite objects in MLJ interface (#19)
• MLJ interface: fit should not mutate model fields (#20)

Merged pull requests:

• CompatHelper: bump compat for "MLJModelInterface" to "1.0" (#21) (@github-actions[bot])
