Shift-Invariant Attribute Scoring for Kolmogorov-Arnold Networks via Shapley Value
TL;DR
Traditional neural networks often lack interpretability, making it hard to understand feature-outcome relationships. ShapKAN, a pruning framework using Shapley value attribution, assesses node importance in a shift-invariant manner.
✦ Why It Matters
Engineers can use ShapKAN to improve model interpretability and efficiency in resource-constrained applications.
Key Takeaways
- Use ShapKAN for effective pruning of Kolmogorov-Arnold Networks.
- Leverage Shapley value for consistent node importance evaluation.
- Enhance model interpretability while maintaining performance.
- Deploy KANs in resource-constrained environments with confidence.
How It Works
ShapKAN utilizes Shapley value attribution to assess the contribution of each node in a KAN. By treating the network as a cooperative game, it calculates the marginal contribution of each node to the overall output, ensuring that the importance rankings are invariant to input shifts.
This shift-invariance is crucial for reliable pruning, as it allows for consistent evaluations regardless of how input data is presented.
