ML library implementing linear boosting with L1 and L2 regularization. For tree based boosting, consider EvoTrees.jl.
Supported loss functions:
- mse (squared-error)
- logistic (logloss) regression
- poisson
- gamma
- tweedie

Build a configuration struct with EvoLinearRegressor. Then EvoLinear.fit takes x::Matrix and y::Vector as inputs, plus optionally w::Vector as weights and fits a linear boosted model.
using EvoLinear
config = EvoLinearRegressor(loss=:mse, nrounds=10, L1=1e-1, L2=1e-2)
m = EvoLinear.fit(config; x, y, metric=:mse)
p = m(x)Splines - Experimental
Number of knots for selected features is defined through a Dict of the form: Dict(feat_id::Int => nknots::Int).
config = EvoSplineRegressor(loss=:mse, nrounds=10, knots = Dict(1 => 4, 5 => 8))
m = EvoLinear.fit(config; x, y, metric=:mse)
p = m(x')
