Abstract EN
A novel methodology, the double layer methodology (DLM), for modeling an individual’s lifestyle and its relationships with health indicators is presented.
The DLM is applied to model behavioral routines emerging from self-reports of daily diet and activities, annotated by 21 healthy subjects over 2 weeks.
Unsupervised clustering on the first layer of the DLM separated our population into two groups.
Using eigendecomposition techniques on the second layer of the DLM, we could find activity and diet routines, predict behaviors in a portion of the day (with an accuracy of 88% for diet and 66% for activity), determine between day and between individual similarities, and detect individual’s belonging to a group based on behavior (with an accuracy up to 64%).
We found that clustering based on health indicators was mapped back into activity behaviors, but not into diet behaviors.
In addition, we showed the limitations of eigendecomposition for lifestyle applications, in particular when applied to noisy and sparse behavioral data such as dietary information.
Finally, we proposed the use of the DLM for supporting adaptive and personalized recommender systems for stimulating behavior change.
