Master Thesis / Project - SENSEI: Sensor Teaching in Multi-Activity classification from Video and Wearables for Wheelchair Users
In this project, we focus on continuous and quantitative monitoring of activities of daily living (ADL) in SCI individuals with the goal of identifying cardiovascular events and PI-related risk behaviors. ADLs specific to SCI patients and their lifestyles shall be discussed and narrowed down in the scope of this work, therefore an autonomous camera-based system is proposed to classify ADLs. The Current work builds on a previous project where a SlowFast network [1] was trained to identify SCI-specific classes and we aim to further improve the classification and temporal resolution for transferring to wearables' time-series data.

Project Background
In this project, we will develop an ADL monitoring system for smart wheelchairs using wearable sensors (i.e., camera, inertial measurement units). The core idea is to classify ADL by leveraging different sensing and feature computation modalities to extract relevant and complementary context bits. For example, the presence of and the interaction with distinctive objects within the camera scene provides strong cue about the ongoing user activity [1, 2, 3]. From another perspective, inertial sensors record distinct orientation and acceleration signatures of ADL-related temporal patterns [4]. Moreover, previous literature provides strong evidence that the combination of video cameras and inertial sensors improves the recognition performance compared to one or the other [5, 6]. Based on the general multi-modal activity recognition paradigm, we are seeking a novel solution tailored to the smart wheelchair. The outcome of the study will be key to analyse the expected cardiovascular function at different moments of the day in free living.

Master's Thesis: AI-powered nap detection from Fitbit data
The uprise of consumer-grade fitness trackers has opened the doors to long-term activity monitoring in the wild in research and clinics. However, Fitbit does not identify napping episodes shorter than 90 minutes. Hence, there is a need to establish a robust algorithm to detect naps.
Keywords

Bachelor Thesis , Master Thesis , ETH Zurich (ETHZ)
Description
We provide the student with a large Fitbit dataset sampled at a 1-minute resolution. Initially, the student must develop suitable algorithms to extract powerful features from the multi-modal data. The student may hand-craft the features and/or leverage state-of-the-art techniques of deep representation learning. These features are then used as input to a model that detects napping episodes. The student is encouraged to start with simple threshold-based algorithms and advance to AI-based approaches. The results from the novel algorithm are then compared against methods from clinical routine. The comparison must include agreement analyses (e.g., Bland-Altman) and performance metrics (e.g., sensitivity and specificity). Eventually, the detected naps are tested as potential biomarkers in the central disorder of hypersomnolence using clustering techniques and statistical tests.
Goal
The student will develop a nap detection algorithm based on artificial intelligence in this project. The student will then assess the predictive power of the novel algorithm against established methods. Finally, the naps are tested as a potential biomarker in the central disorder of hypersomnolence.
