VSEngineering Contradiction Analysis

1Reliability

If automated data augmentation processes employ joint optimization of augmentation parameters and neural network parameters, then model performance can be improved, but the search space size increases to 10^32 and training time significantly increases

Engineering Contradiction:

Solution Approach 1:

The patent segments the joint optimization problem into two separate optimization problems: (1) optimizing augmentation parameters independently using a unidimensional search space, and (2) optimizing neural network parameters using standard backpropagation. This segmentation reduces the search space from 10^32 to a manageable size while maintaining model performance.

Inventive Principle:

Solution Approach 2:

The patent transforms the high-dimensional joint optimization problem into a unidimensional search space by parameterizing augmentation transformations using a single parameter θ. This dimensionality reduction allows efficient optimization without sacrificing the ability to explore diverse augmentation strategies.

Inventive Principle:
