Sensor Artificial Intelligence and its Application to Space Systems - A White Paper
A white paper resulting from the 1st Workshop on Sensor AI, April 2020; organized by DLR and the ECDF.Information and communication technologies have accompanied our everyday life for years. A steadily increasing number of computers, cameras, mobile devices, etc. generate more and more data, but at the same time we realize that the data can only partially be analyzed with classical approaches. The research and development of methods based on artificial intelligence (AI) made enormous progress in the area of interpretability of data in recent years. With growing experience, both, the potential and limitations of these new technologies are increasingly better understood. Typically, AI approaches start with the data from which information and directions for action are derived. However, the circumstances under which such data are collected and how they change over time are rarely considered. A closer look at the sensors and their physical properties within AI approaches will lead to more robust and widely applicable algorithms. This holistic approach which considers entire signal chains from the origin to a data product, "Sensor AI", is a highly relevant topic with great potential. It will play a decisive role in autonomous driving as well as in areas of automated production, predictive maintenance or space research. The goal of this white paper is to establish "Sensor AI" as a dedicated research topic. We want to exchange knowledge on the current state-of-the-art on Sensor AI, to identify synergies among research groups and thus boost the collaboration in this key technology for science and industry
CycleSense: Detecting Near Miss Incidents in Bicycle Traffic from Mobile Motion Sensors
In cities worldwide, cars cause health and traffic problems which could be
partly mitigated through an increased modal share of bicycles. Many people,
however, avoid cycling due to a lack of perceived safety. For city planners,
addressing this is hard as they lack insights into where cyclists feel safe and
where they do not. To gain such insights, we have in previous work proposed the
crowdsourcing platform SimRa, which allows cyclists to record their rides and
report near miss incidents via a smartphone app. In this paper, we present
CycleSense, a combination of signal processing and Machine Learning techniques,
which partially automates the detection of near miss incidents. Using the SimRa
data set, we evaluate CycleSense by comparing it to a baseline method used by
SimRa and show that it significantly improves incident detection
Regularized linear discriminant analysis of EEG features in dementia patients
The present study explores if EEG spectral parameters can discriminate between healthy elderly controls (HC), Alzheimer’s disease (AD) and vascular dementia (VaD) using. We considered EEG data recorded during normal clinical routine with 114 healthy controls (HC), 114 AD, and 114 VaD patients. The spectral features extracted from the EEG were the absolute delta power, decay from lower to higher frequencies, amplitude, center and dispersion of the alpha power and baseline power of the entire frequency spectrum. For discrimination, we submitted these EEG features to regularized linear discriminant analysis algorithm with a 10-fold cross-validation. To check the consistency of the results obtained by our classifiers, we applied bootstrap statistics. Four binary classifiers were used to discriminate HC from AD, HC from VaD, AD from VaD, and HC from dementia patients (AD or VaD). For each model, we measured the discrimination performance using the area under curve (AUC) and the accuracy of the cross-validation (cv-ACC). We applied this procedure using two different sets of predictors. The first set considered all the features extracted from the 22 channels. For the second set of features, we automatically rejected features poorly correlated with their labels. Fairly good results were obtained when discriminating HC from dementia patients with AD or VaD (AUC = 0.84). We also obtained AUC = 0.74 for discrimination of AD from HC, AUC = 0.77 for discrimination of VaD from HC, and finally AUC = 0.61 for discrimination of AD from VaD. Our models were able to separate HC from dementia patients, and also and to discriminate AD from VaD above chance. Our results suggest that these features may be relevant for the clinical assessment of patients with dementia

GreenDB: Toward a Product-by-Product Sustainability Database
The production, shipping, usage, and disposal of consumer goods have a
substantial impact on greenhouse gas emissions and the depletion of resources.
Modern retail platforms rely heavily on Machine Learning (ML) for their search
and recommender systems. Thus, ML can potentially support efforts towards more
sustainable consumption patterns, for example, by accounting for sustainability
aspects in product search or recommendations. However, leveraging ML potential
for reaching sustainability goals requires data on sustainability.
Unfortunately, no open and publicly available database integrates
sustainability information on a product-by-product basis. In this work, we
present the GreenDB, which fills this gap. Based on search logs of millions of
users, we prioritize which products users care about most. The GreenDB schema
extends the well-known schema.org Product definition and can be readily
integrated into existing product catalogs to improve sustainability information
available for search and recommendation experiences. We present our proof of
concept implementation of a scraping system that creates the GreenDB dataset
A Rapid Review on Application Scenarios for Artificial Intelligence in Nursing Care – Review Protocol
This is a protocol for a rapid review that aims to identify and systemize scientific publications on described and researched application scenarios for AI in nursing practice considering different care settings, dimensions of AI and aspects of ethical, legal and social implications (ELSI). Overarching goal is the display of typical abilities of AI that aim to support nursing care-specific challenges and requirements. Furthermore, barriers for suitable application scenarios will be identified
