XAI: Explanations of AI decisions in Image classification tasks: Methods and questions


Today AI tools are largely used for information analysis and decision making. For critical applications such as healthcare, security… the users of AI tools need to understand why the system has taken such a decision.

Image classification is one of the most frequent problems AI tools such as Deep Neural Networks are designed for. The explanation methods aim to highlight elements in the input accordingly to their contribution to the final decision.

In case of image classification tasks we are speaking of pixel importance or explanation maps. The methods of their building can be divided into two categories: the so-called black-box methods and white -box methods.

In the talk we will present the taxonomy of the main explainers nowadays. We will go into details of some methods developed by us and also speak about evaluation of explainers, which is an open research question per se.
