What is KAN?

Kolmogorov-Arnold Network (KAN) is a novel neural network architecture that replaces traditional fixed activation functions with learnable activation functions, typically based on splines.

Core Principle

Unlike MLPs which have fixed activation functions at nodes, KANs place learnable activation functions on the edges, effectively parametrizing them as splines. This provides theoretical precision for function approximation, inheriting O(h^4) polynomial bounds.

Application to Audio

This unique architecture makes KAN a promising candidate for Implicit Neural Representations (INRs) in audio, enabling high-fidelity reconstruction by approximating sound signals as a linear combination of basis functions, similar to FFT or wavelets.

Hypernetwork Integration

FewSound is a hypernetwork-based meta-learning method designed to enhance KAN's utility for audio representation. It uses a hypernetwork to adapt universal INR weights for specific audio tasks.

Key Components

  • Encoding Network E(): Processes raw audio input into a low-dimensional representation (Es).
  • Universal Weight Encoder G(): Compresses universal weights (θ) of the target KAN into a representation (Eθ).
  • Hypernetwork H(): Takes concatenated Es and Eθ to output an adjustment (Δθ) to the universal weights.

Dynamic Parameter Update

The final target model parameters (θ') for KAN are derived by adding this adjustment (θ' = θ + Δθ). This allows FewSound to dynamically generate and optimize KAN parameters for entirely different sounds efficiently, enabling few-shot learning.

KAN's Standalone Performance

KAN demonstrates superior perceptual performance over previous INRs, achieving the lowest Log-Spectral Distance of 1.29 and the highest Perceptual Evaluation of Speech Quality of 3.57 for 1.5s audio. It is competitive across most metrics, especially for shorter audio signals.

FewSound's Superiority

FewSound significantly outperforms the state-of-the-art HyperSound, achieving a 33.3% improvement in MSE, a 60.87% increase in SI-SNR, and an 8.66% increase in PESQ. This highlights the effectiveness of hypernetwork-enhanced KANs for robust and adaptable audio representation.

Architecture Impact

While FewSound with NeRF as the target network often shows strong overall performance, KAN remains highly competitive, especially for HyperSound models where KAN can be superior in several key metrics across various datasets.

Feature KAN Advantages Traditional INR Limitations (e.g., SIREN, NeRF)
Perceptual Quality (PESQ)
  • ✓ Highest PESQ score (3.57 for 1.5s audio), indicating superior human-like sound perception.
  • ✓ Often lower PESQ scores, struggling to capture fine auditory nuances.
Spectral Fidelity (LSD)
  • ✓ Lowest Log-Spectral Distance (1.29 for 1.5s audio), signifying closer spectral match to ground truth.
  • ✓ Generally higher LSD, indicating less accurate frequency representation.
Architecture
  • Learnable activation functions (splines) on edges, leading to higher expressiveness and theoretical approximation bounds.
  • ✓ Fixed activation functions (e.g., ReLU, Sine, Gabor) can limit flexibility and detail capture.
Adaptability with Hypernetworks
  • ✓ Successfully integrated with FewSound hypernetwork for efficient, few-shot adaptation to new audio tasks.
  • ✓ While some INRs use hypernetworks, KAN's learnable functions may offer unique advantages in adaptation.
