A physics-inspired approach to feature selection that uses spring dynamics simulations to create explainable, relationship-aware feature selection. Watch your features organize themselves through the elegant laws of physics!
Traditional methods tell you WHAT features to select. We show you WHY.
| Traditional Methods | Spring Dynamics | |
|---|---|---|
| Explanation | Black box scores | Visual, intuitive physics |
| Relationships | Ignores correlations | Naturally handles feature interactions |
| Decision Process | Statistical thresholds | Emergent from simulation |
| Interpretability | Technical scores | "Feature A clusters with B and C" |
- π¬ Physics-Inspired: Uses spring dynamics to model feature relationships
- ποΈ Visual & Explainable: See exactly why each feature was selected
- π€ Relationship-Aware: Considers how features work together, not just individually
- β‘ Performance: Competitive accuracy with state-of-the-art methods
- π¨ Interactive: Live 3D visualizations of the feature selection process
Imagine your features as celestial bodies in space:
- π΄ Compressed Springs = Highly correlated features that work together
- π’ Neutral Springs = Moderately related features
- π΅ Extended Springs = Unrelated or redundant features
- β Central Features = Important anchors of the feature space
- π Distant Features = Potential noise candidates for removal
The physics simulation naturally reveals the true underlying structure of your data!

- Discovered 3 natural feature clusters matching known biological pathways
- Selected 12 features with 96% accuracy (vs 14 features with 95% for traditional methods)
- Provided doctors with intuitive "feature family" explanations

selector.generate_publication_report()- Correlation Mapping: Convert feature correlations to spring strengths
- Simulation: Run physics simulation to equilibrium
- Cluster Analysis: Identify natural feature groupings
- Score Integration: Combine spring dynamics with performance metrics
- Diversity Enforcement: Avoid redundant feature selection
The spring force between features i and j is given by:
F_spring = k_ij * (distance_ij - rest_length_ij)
Where:
-
k_ij= spring strength (proportional to correlation) -
distance_ij= current distance between features -
rest_length_ij= natural distance based on correlation strength -
