Wi-Fi and Bluetooth Contact Tracing Without User Intervention
Brosnan Yuen, Yifeng Bie, Duncan Cairns +5
Previous contact tracing systems required the users to perform many manual actions, such as installing smartphone applications, joining wireless networks, or carrying custom user d…
Passive Indoor Localization with WiFi Fingerprints
Minh Tu Hoang, Brosnan Yuen, Kai Ren +5
This paper proposes passive WiFi indoor localization. Instead of using WiFi signals received by mobile devices as fingerprints, we use signals received by routers to locate the mob…
Universal Activation Function For Machine Learning
Brosnan Yuen, Minh Tu Hoang, Xiaodai Dong +1
This article proposes a Universal Activation Function (UAF) that achieves near optimal performance in quantification, classification, and reinforcement learning (RL) problems. For…
A CNN-LSTM Quantifier for Single Access Point CSI Indoor Localization
Minh Tu Hoang, Brosnan Yuen, Kai Ren +5
This paper proposes a combined network structure between convolutional neural network (CNN) and long-short term memory (LSTM) quantifier for WiFi fingerprinting indoor localization…
Semi-Sequential Probabilistic Model For Indoor Localization Enhancement
Minh Tu Hoang, Brosnan Yuen, Xiaodai Dong +3
This paper proposes a semi-sequential probabilistic model (SSP) that applies an additional short term memory to enhance the performance of the probabilistic indoor localization. Th…
Hardware/Software Codesign for Training/Testing Multiple Neural Networks on Multiple FPGAs
Brosnan Yuen
Most neural network designs for FPGAs are inflexible. In this paper, we propose a flexible VHDL structure that would allow any neural network to be implemented on multiple FPGAs. M…
A Soft Range Limited K-Nearest Neighbours Algorithm for Indoor Localization Enhancement
Minh Tu Hoang, Yizhou Zhu, Brosnan Yuen +5
This paper proposes a soft range limited K nearest neighbours (SRL-KNN) localization fingerprinting algorithm. The conventional KNN determines the neighbours of a user by calculati…
Classifying Multi-Gas Spectrums using Monte Carlo KNN and Multi-Resolution CNN
Brosnan Yuen
A Monte Carlo k-nearest neighbours (KNN) and a multi-resolution convolutional neural network (CNN) were developed to detect the presences of multiple gasses in near infrared (IR) s…
Multi-label Classification with Optimal Thresholding for Multi-composition Spectroscopic Analysis
Luyun Gan, Brosnan Yuen, Tao Lu
In this paper, we implement multi-label neural networks with optimal thresholding to identify gas species among a multi gas mixture in a cluttered environment. Using infrared absor…
Recurrent Neural Networks For Accurate RSSI Indoor Localization
Minh Tu Hoang, Brosnan Yuen, Xiaodai Dong +3
This paper proposes recurrent neuron networks (RNNs) for a fingerprinting indoor localization using WiFi. Instead of locating user's position one at a time as in the cases of conve…
Low Cost Radiation Hardened Software and Hardware Implementation for CubeSats
Brosnan Yuen, Mihai Sima
CubeSats are small satellites used for scientific experiments because they cost less than full sized satellites. Each CubeSat uses an on-board computer. The on-board computer perfo…
