Engineering Contradiction Analysis
1Productivity
If pre-trained models are publicly available for transfer learning, then data availability and computational resource requirements are reduced, but security vulnerabilities increase due to easier identification of attacks
Solution Approach 1:
The system performs preliminary security testing by generating adversarial inputs and evaluating them against the pre-trained model before deployment. This includes defining evaluation metrics, selecting defense algorithms, and testing the model's vulnerability to various attacks in advance, allowing security issues to be identified and addressed before the model is deployed to production environments
Solution Approach 2:
The system applies defense algorithms as preliminary protective measures against anticipated adversarial attacks. By selecting and applying defenses from a predefined set based on evaluation metrics, the system proactively counteracts potential security threats before they can exploit the model in production
2Reliability
If evaluation metrics are defined to test model responses against adversarial inputs, then model security can be assessed, but computational resources and time requirements increase
Solution Approach 1:
The system extracts and isolates specific evaluation metrics from the overall model assessment process. By defining discrete metrics such as accuracy measurements and similarity measures that can be independently calculated, the system enables focused security evaluation without requiring complete re-testing of the entire model system
Solution Approach 2:
The system uses pre-generated adversarial inputs as test cases that can be reused across multiple evaluation scenarios. By creating a set of adversarial examples once and using them to test different defense algorithms and evaluation metrics, the system avoids the need to generate new adversarial inputs for each evaluation, significantly reducing computational overhead
3Reliability
If multiple defenses are selected and incorporated into the model, then model robustness against attacks improves, but device complexity increases
Solution Approach 1:
The system applies different defense algorithms to different aspects of the model based on specific vulnerability assessments. By selecting defenses that target particular types of adversarial attacks identified through evaluation metrics, the system provides localized protection where needed rather than applying uniform complexity across the entire system
Solution Approach 2:
The system combines multiple defense algorithms into a unified defense mechanism that works together to protect the model. By integrating selected defenses from the predefined set into a cohesive security layer, the system achieves enhanced robustness while managing complexity through coordinated operation of defense components

AI summary
Techniques are disclosed for providing a framework for fast prototyping attacks and defenses on transfer learning settings. For example, a system can include at least one processing device including a processor coupled to a memory, the at least one processing device being configured to perform the following steps: defining a set of evaluation metrics, each evaluation metric configured to test responses by a machine learning model when applying a given defense among a set of defenses against a set of adversarial inputs generated for the model; selecting one or more defenses from the set of defenses based on the evaluation metrics; and generating a secured model based on incorporating the selected defenses into the model.
