The transformer model attends to the regions that are relevant for path loss prediction and, therefore, scales efficiently to maps of different size.

We propose generative channel modeling to learn statistical channel models from channel input-output measurements.

Our work consists of two sides: We introduce sampling attack, a novel membership inference technique that unlike other standard membership adversaries is able to work under severe restriction of no access to scores of the victim model.

Personal photos of individuals when shared online, apart from exhibiting a myriad of memorable details, also reveals a wide range of private information and potentially entails privacy risks (e. g., online harassment, tracking).

We find such passive defenses ineffective against DNN stealing attacks.

We formulate model functionality stealing as a two-step approach: (i) querying a set of input images to the blackbox model to obtain predictions; and (ii) training a "knockoff" with queried image-prediction pairs.

At the core of FL is a network of anonymous user devices sharing training information (model parameter updates) computed locally on personal data.

Third, we propose models that predict user specific privacy score from images in order to enforce the users' privacy preferences.
