A Lightweight Algorithm for Classifying Ex Vivo Tissues Samples
Tzu-Hao Li, Ethan Murphy, Allaire Doussan +2
In this paper, we present a novel algorithm for classifying ex vivo tissue that comprises multi-channel bioimpedance analysis and a hardware neural network. When implemented in a m…
Analog Gated Recurrent Neural Network for Detecting Chewing Events
Kofi Odame, Maria Nyamukuru, Mohsen Shahghasemi +2
We present a novel gated recurrent neural network to detect when a person is chewing on food. We implemented the neural network as a custom analog integrated circuit in a 0.18 um C…
Extracting Fractional Inspiratory Time from Electrocardiograms
Maria Nyamukuru, Kofi Odame
Non-invasive at-home monitoring of lung and lung airways health enables the early detection and tracking of respiratory diseases like asthma and chronic obstructive pulmonary disea…
Inferring COPD Severity from Tidal Breathing
Kofi Odame, Graham Atkins, Maria Nyamukuru +1
Objective: To develop an algorithm that can infer the severity level of a COPD patient's airflow limitation from tidal breathing data that is collected by a wearable device. Method…
