In sensitive areas, such as self-driving cars, medical diagnostics, and loan approvals, it is essential to guarantee that AI decisions are sensible and free from serious errors. However, AI systems can sometimes make mistakes, and these errors can have serious consequences.
The researchers focused on developing methods to analyze neural networks that have been trained to classify input data into specific categories. They identified two critical characteristics that these networks must possess robustness and fairness. Robustness ensures that the network produces the same result for similar input data, while fairness guarantees that the network is not biased towards specific parameters, such as gender or ethnicity.
Existing verification techniques typically focus on local definitions of fairness and robustness, checking for these properties in specific inputs. However, the researchers aimed to define global properties, ensuring that the neural network always exhibits these characteristics, regardless of the input.
To achieve this, they developed a system based on confidence, which checks for certain properties and provides a level of confidence in the results. This approach allows for the identification of edge cases where small changes in input may lead to different outputs, while ensuring that the network is globally robust in other regions.
The researchers also had to overcome the challenge of analyzing the entire input space, which can be computationally intensive. They developed mathematical tricks to simplify the process, allowing for reliable and rigorous statements about the neural network as a whole.
This breakthrough has significant implications for human-AI collaboration, ensuring that AI systems can be trusted to make critical decisions. By certifying the safety and fairness of neural networks, we can confidently rely on AI to make decisions that are sensible, unbiased, and free from serious errors.
The researchers' work will be presented at the 36th International Conference on Computer Aided Verification (CAV 2024) in Montreal, Canada.
