The Efficacy of the Connect America Fund in Addressing US Internet Access Inequities
Published in ACM SIGCOMM ’24, 2024
In this article, a novel time-frequency (TF) domain deep learning approach is proposed for the automated detection of atrial fibrillation (AF) using multi-lead ECG signals. The wavelet-based synchrosqueezing transform (WSST) is used to evaluate the TF image of each lead ECG signal. Furthermore, the modified vision transformer (ViT) model detects AF arrhythmia using the WSST-based TF images of the three best lead ECG signals. The proposed approach is tested using a public database’s multi-lead ECG time series. The results reveal that the suggested WSST-based modified ViT model has obtained the accuracy, precision, recall, and F1-score values of 95.50%, 93.36%, 98.00%, and 0.957, respectively.

Time-Frequency Domain Modified Vision Transformer Model for Detection of Atrial Fibrillation using Multi-lead ECG Signals

The Efficacy of the Connect America Fund in Addressing US Internet Access Inequities
Published in ACM SIGCOMM ’24, 2024
Residential fixed broadband internet access in the US remains inequitable, despite significant taxpayer investment. This paper evaluates the efficacy of the Connect America Fund (CAF), which subsidizes new broadband monopolies in underserved areas to provide internet access comparable to that in urban regions.
