Smart Devices are Different: Assessing and MitigatingMobile Sensing Heterogeneities for Activity Recognition
Allan Stisen,Henrik Blunck,Sourav Bhattacharya,Thor Siiger Prentow,Mikkel Baun Kjærgaard,Anind K. Dey,Tobias Sonne,Mads Møller Jensen +7 more
TL;DR: It is indicated that on-device sensor and sensor handling heterogeneities impair HAR performances significantly and a novel clustering-based mitigation technique suitable for large-scale deployment of HAR is proposed, where heterogeneity of devices and their usage scenarios are intrinsic.
Proceedings ArticleDOI
DeepX: a software accelerator for low-power deep learning inference on mobile devices
Nicholas D. Lane,Sourav Bhattacharya,Petko Georgiev,Claudio Forlivesi,Lei Jiao,Lorena Qendro,Fahim Kawsar +6 more
TL;DR: Experiments show, DeepX can allow even large-scale deep learning models to execute efficently on modern mobile processors and significantly outperform existing solutions, such as cloud-based offloading.
Proceedings ArticleDOI
Sparsification and Separation of Deep Learning Layers for Constrained Resource Inference on Wearables
TL;DR: This paper proposes SparseSep, a new approach that leverages the sparsification of fully connected layers and separation of convolutional kernels to reduce the resource requirements of popular deep learning algorithms, and allows large-scale DNNs and CNNs to run efficiently on mobile and embedded hardware with only minimal impact on inference accuracy.
Journal ArticleDOI
Multimodal Deep Learning for Activity and Context Recognition
Valentin Radu,Catherine Tong,Sourav Bhattacharya,Nicholas D. Lane,Cecilia Mascolo,Mahesh K. Marina,Fahim Kawsar +6 more
TL;DR: This paper studies the benefits of adopting deep learning algorithms for interpreting user activity and context as captured by multi-sensor systems under wearable data by evaluating four variations of deep neural networks based either on fully-connected Deep Neural Networks (DNNs) or Convolutional Neural networks (CNNs).
Proceedings ArticleDOI
An Early Resource Characterization of Deep Learning on Wearables, Smartphones and Internet-of-Things Devices
TL;DR: The aim of this investigation is to begin to build knowledge of the performance characteristics, resource requirements and the execution bottlenecks for deep learning models when being used to recognize categories of behavior and context.
