| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary The proposed sensitivity analysis framework uses set-valued mapping to understand how deep neural network solutions respond to training data perturbations. The focus is on the sensitivity of the solution set, rather than a single solution, as DNNs may not have unique minima and algorithms can produce different solutions with minor input data changes. The framework provides a deeper understanding of robustness and reliability during training by analyzing the expansion and contraction of the solution set in response to perturbations. This approach does not require non-singular Hessian assumptions. Set-level metrics, including distance, convergence, derivatives, and stability, are developed to prove that Fully Connected Neural Networks exhibit Lipschitz-like properties. A graphical-derivative-based method is introduced for general neural networks (e.g., Resnet) to estimate the new solution set following perturbations without retraining. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary This paper helps us understand how deep learning models behave when their training data changes slightly. It looks at how the model’s solutions change in response to these small changes, rather than just focusing on a single solution. This is important because deep learning models can have many possible solutions and may not always work well if their training data is changed. The paper proposes a new way of analyzing these models that doesn’t require making certain assumptions about how they work. It also introduces new metrics to measure how well the model’s solutions are changing in response to the changes in its training data. |
