Using RF Signals to Generate Indoor Maps

ACM TRANSACTIONS ON SENSOR NETWORKS, 19(1).

By: U. Khan n, R. Venkatnarayan  n & M. Shahzad n

author keywords: RF maps; radar; through wall mapping; indoor mapping
TL;DR: This article proposes RFMap, which generates fully connected maps, and does not require the measurement setup to be moved along the sides of the buildings, and trains a deep generative adversarial network (GAN) to intelligently predict the missing information. (via Semantic Scholar)

Contactless Monitoring of PPG Using Radar

PROCEEDINGS OF THE ACM ON INTERACTIVE MOBILE WEARABLE AND UBIQUITOUS TECHNOLOGIES-IMWUT, 6(3).

By: U. Khan n, L. Rigazio & M. Shahzad n

author keywords: Radar; PPG; Deep Learning; Vital Signs; Attention; Encoder Decoder Networks
TL;DR: Evaluations show that VitaNet accurately estimates the PPG waveform and its derivatives with high accuracy, significantly improves the heart rate and heart rate variability estimates from the prior works, and also accurately estimates several useful PPG features. (via Semantic Scholar)

Left or Right: A Peek into the Political Biases in Email Spam Filtering Algorithms During US Election 2020

PROCEEDINGS OF THE ACM WEB CONFERENCE 2022 (WWW'22), pp. 2491–2500.

By: H. Iqbal n, U. Khan n, H. Khan n & M. Shahzad n

author keywords: US Elections; Emails; Spam; Bias; Political Bias; Algorithm Bias
TL;DR: It is observed that the SFAs of different email services indeed exhibit biases towards different political affiliations, and the impact of the interactions (such as reading or marking emails as spam) of email recipients on these biases is studied. (via Semantic Scholar)
