Will my system work if image quality starts to drop significantly? If my system works at a given occlusion level, how much stronger can occlusion get before the system starts to underperform? I have faced such issues repeatedly in the past, all related to an overarching question: How robust is my model and when does it break?

As users increasingly rely on Large Language Models (LLMs) to accomplish their daily tasks, their concerns about the potential leakage of private data by these models have surged.

A: At the beginning there was 10 cookies, then 2 of them were eaten, so 8 cookies were left. Then 5 cookieswere given toa friend, so 3 cookies were left. 3 cookies + 2 boxes of 2 cookies (4 cookies) = 7 cookies. Youhave 7 cookies.

As developers, we often face daunting questions as we build a model toward production. For instance:
I have faced such issues repeatedly in the past, all related to an overarching question: How robust is my model and when does it break?
We all know that building production-level computer vision systems is challenging. The number of factors that can influence input images or videos in the real world is daunting. As such, gathering evidence that the systems we built will work under these varying factors is key and a major challenge for that final push to production.
Ultimately, we as developers carry the burden of proof.
A major tool at our disposal to bring transparency to how a computer vision system will perform in the real world and provide answers to the questions above is stress-testing. Systematically answering such questions (for example, how occluded do objects have to be before my systems break) provides two major advantages:
1. If the system’s robustness is unacceptably low (for example, the system is highly affected by increased occlusion), gathering the right data to increase robustness becomes easier to strategize (by prioritizing images with highly occluded objects). This includes generating the right synthetic data and augmentations.
2. It helps communicate to the product’s users its limitations, ultimately ensuring transparency and safer use.
The fundamental insight relies on the idea of metamorphic relations. Some visual changes result in clear, predictable effects in the image’s annotations. For example, a rotated dog is still a dog, or a horizontal flip on a gauge reading should result in a symmetric reading. This allows us to measure performance while exploring such visual changes using techniques from the fuzz testing world. To learn more about these, take a look at our blog post on metamorphic relations and fuzz testing.
