SIM-IPS: Stacked Intelligent Metasurface-Based Indoor Positioning System by Aisha Javed, Naveed Ul Hassan, Marco Di Renzo, Chau Yuen

“…In this paper, we introduce a stacked intelligent metasurface-based indoor positioning system (SIM-IPS), which is a novel IPS developed using an SIM, a transmissive metasurface with multiple layers of independently controlled meta-atoms. These layers function analogously to the hidden layers in a deep neural network (DNN) and enable advanced beamforming in the electromagnetic (EM) wave domain, thus improving the control of the power distribution at the receiver plane. …”

Attention-Based Batch Normalization for Binary Neural Networks by Shan Gu, Guoyin Zhang, Chengwei Jia, Yanxia Wu

“…Experimental analyses show that our ABN method helps to capture image features, provide additional activation-like functions, and increase the imbalance of the activation distribution, and these features help to improve the performance of BNNs. …”

The Method for Generating a Set of Reference Images for Assessing the Condition of Critical Infrastructure Facilities Using Mobile Robots by Tymochko O., Burdin M., Najafli E., Tsukan O., Olizarenko S., Biryukov I., Tiurina V., Zakirov S., Padalka I.

“…The difference from known works is that the perspective and scale distortions are considered at the stage of formation of a set of reference images, which ensures high accuracy of the system functioning in conditions of orientation and sighting geometry changes.…”
