Abstract

In the context of Few-Shot Learning (specifically limited to ~100 samples per class), this research aims to utilize a systematic Pipeline to discover the optimal combination of foundational data augmentation operations. The objective is to verify that a superimposed strategy (multi-op) significantly enhances model accuracy and robustness compared to single-operation baselines.

key Innovations

  • Stability-Aware Search: A novel three-stage pipeline initialized based on “Human Priors” restricts the search space to avoid overfitting.
  • Multi-Op Superposition: Verifying that rational combinations of operations outperform single operations.
  • Joint Search: Moving away from fixed probability constraints to jointly optimize magnitude (mm) and probability (pp).

Methodology

  1. Phase A: Breadth-first screening to identify effective individual operations.
  2. Phase B: Depth-first parameter tuning to find the optimal magnitude and probability.
  3. Phase C: Greedy superposition to construct the final combinatorial strategy.
