Query: Autonomous Human Activity Classification from Ego-vision Camera and
  Accelerometer Data   There has been significant amount of research work on human activity
classification relying either on Inertial Measurement Unit (IMU) data or data
from static cameras providing a third-person view. Using only IMU data limits
the variety and complexity of the activities that can be detected. For
instance, the sitting activity can be detected by IMU data, but it cannot be
determined whether the subject has sat on a chair or a sofa, or where the
subject is. To perform fine-grained activity classification from egocentric
videos, and to distinguish between activities that cannot be differentiated by
only IMU data, we present an autonomous and robust method using data from both
ego-vision cameras and IMUs. In contrast to convolutional neural network-based
approaches, we propose to employ capsule networks to obtain features from
egocentric video data. Moreover, Convolutional Long Short Term Memory framework
is employed both on egocentric videos and IMU data to capture temporal aspect
of actions. We also propose a genetic algorithm-based approach to autonomously
and systematically set various network parameters, rather than using manual
settings. Experiments have been performed to perform 9- and 26-label activity
classification, and the proposed method, using autonomously set network
parameters, has provided very promising results, achieving overall accuracies
of 86.6\% and 77.2\%, respectively. The proposed approach combining both
modalities also provides increased accuracy compared to using only egovision
data and only IMU data.
