Reliable and Reconfigurable MET Estimation Using Wearables

Parastoo Alinia, Ramin Fallahzadeh, Ali Rokni, and Hassan Ghasemzadeh

project1 We introduce a power-aware sensor localization approach that allows users to wear the sensors on different body locations without the need for adhering to a specific installation protocol. Furthermore, we propose a novel transductive transfer learning approach, which gives end-users the ability to add new sensors to the network without the need for collecting new training data. This is accomplished by transferring the knowledge of already trained sensors to the untrained sensors in real-time.

Cross-Domain Step Counting in Wearable Sensors

Parastoo Alinia, Christopher Connolly, and Hassan Ghasemzadeh

project2 We introduce a filter-based step counting algorithm that is reliable against various walking speeds and intensities. ParaLabel aims to learn the algorithm parameters autonomously in new domains (e.g., in new users) without a need for collecting sensor data and manually tuning the algorithm parameters. We formulate this problem as a transfer learning problem where parameters of the algorithm in a new domain are mapped onto a parameter bank containing previously fine-tuned parameters in a different domain.

Sequence to Sequence Classification for Lying Posture Tracking

Parastoo Alinia, Hassan Ghasemzadeh, and Saman Parvaneh

project3 In this study, we implement two models (feature-based and deep learning models) to detect three main lying postures (lying supine, prone, and on the sides) from a single tri-axial accelerometer sensor. The feature-based model is an ensemble tree classifier which is built on 48 time-domain features. The deep learning model is a long short-term memory (LSTM) classifier that is trained on raw accelerometer data. In this study, we 1) compare performance of feature-based and deep learning models for lying posture detection, 2) identify the optimal sensor wearing site (from nine different body locations including the chest, right and left thigh, ankle, arm, and wrist) for accurate lying posture detection using a single accelerometer, and 3) identify the optimal set of time-domain features in feature-based model for accurate lying posture detection.
