UAV-aided RF Mapping for Sensing and Connectivity in Wireless Networks [article]

David Gesbert, Omid Esrafilian, Junting Chen, Rajeev Gangula, Urbashi Mitra
2022 arXiv   pre-print
The use of unmanned aerial vehicles (UAV) as flying radio access network (RAN) nodes offers a promising complement to traditional fixed terrestrial deployments.  ...  In practice, the selection of a proper location or trajectory for the UAV very much depends on local terrain features, including the position of surrounding radio obstacles.  ...  As an alternative to probabilistic channel models, trajectory design can instead exploit channel prediction based on local terrain features.  ...

phishGILLNET—phishing detection methodology using probabilistic latent semantic analysis, AdaBoost, and co-training

Venkatesh Ramanathan, Harry Wechsler
2012 EURASIP Journal on Information Security  
The first layer (phishGILLNET1) employs Probabilistic Latent Semantic Analysis (PLSA) to build a topic model.  ...  The topic model handles synonym (multiple words with similar meaning), polysemy (words with multiple meanings), and other linguistic variations found in phishing.  ...  Most of the above research is limited to website detection; however, we propose a generic content-based approach that can be applied to email, web pages, blogs, and social networking posts.  ...
