“…To make this inference of trusted ties, we use the recently emerging direction of using deep learning approaches for sensor and ubiquitous data [12][13][14][15]. However, while current deep learning architectures are typically well-designed to handle low-level neighborhood notions within an entity of interest (e.g., neighboring pixels within an image or the next Bluetooth reading within a stream), they typically do not consider the inter-entity notions of a neighborhood.…”

Interpersonal trust mediates multiple socio-technical systems and has implications for personal and societal well-being. Consequently, it is crucial to devise novel machine learning methods to infer interpersonal trust automatically using mobile sensor-based behavioral data. Considering that social relationships are often affected by neighboring relationships within the same network, this work proposes using a novel neighbor-aware deep learning architecture (NADAL) to enhance the inference of interpersonal trust scores. Based on analysis of call, SMS, and Bluetooth interaction data from a one-year field study involving 130 participants, we report that: (1) adding information about neighboring relationships improves trust score prediction in both shallow and deep learning approaches; and (2) a custom-designed neighbor-aware deep learning architecture outperforms a baseline feature concatenation based deep learning approach. The results obtained at interpersonal trust prediction are promising and have multiple implications for trust-aware applications in the emerging social internet of things.
