But just as Corona has left its mark on our lives, many walkers also leave unwelcome traces in the environment.

Whether intentional or not, littering harms nature and makes your daily walk less worthwhile to experience. Even if it’s on…

Instance-based visualization techniques for CNNs: An overview for non-AI-experts to comprehend classification results

TL;DR For the enforcement of Convolutional Neural Networks (CNN), it is crucial that users accept the model and trust in the classification. However, since the networks are not intuitively comprehensible, non-transparent misclassification leads to a loss of trust in the model. To increase comprehensibility, visualization methods can be used that show the relevance of the image regions to non-AI experts. In the following post, some of them are presented and their use is evaluated based on selected evaluation criteria. The main groups of instance-based visualization methods are considered: perturbation-based, activation-based, backpropagation-based and concept-based.

The post was written as part of…
