What do we do?

We study specific AI models applied to network problems like mobile traffic forecasting and resource allocation and develop tools that augment the understanding of the corresponding models’ logic and their robustness. We strive to ensure that explanations are comprensible and actionable, i.e., network experts can relate the semantic of the explanations with their expert knowledge and the knowledge of the explanations can be capitalized by routines and algorithms for further optimizations. Examples of such tools are DeExp, EXPLORA, and AIChronoLens.
