When Hanna Wallach first started testing machine learning models, the tasks were well-defined and easy to evaluate. Did the model correctly identify the cats in an image? Did it accurately predict the ...

Abstract: We consider the problem of detecting and mitigating the effect of multipath on GNSS observations. In particular, we focus on carrier-phase observations that are collected at an array of GNSS ...

Abstract: A preliminary study concerning the design of a simultaneous multibeam antenna system is addressed. The exploitation of radiating elements with different radiation patterns is at the basis of ...
