Debugging complex AI Solutions

In our latest release, version, we have added a new powerful debugging technique that visually shows the  areas within an image that impact the firing of each label, and do so with the newly released CUDA 11.2/cuDNN 8.1 from NVIDIA.

Model Impact Visualization

The example above shows the areas within the CIFAR-10 [1] dataset images that actually have the most impact on firing each detected label.

Unlike the label impact visualization, originally inspired by [2], the model impact visualization shows the impact of each area of the image space on all labels, whereas the label impact shows the impact on a single label.
