Model Settings

Lasso (L1)

L1 regularized linear regression with feature selection

Fit Intercept

Include bias term in the model

Alpha (α)1.00

10⁻³ = weak1 = default10³ = strong

Log-scale: higher α → more coefficients driven to exactly zero (sparser model).

Train / Test Split

Holdout proportion for evaluation

Test Size20%

Projection

2D visualization method

PCA for quick linear projection. UMAP for complex manifolds.
