1. The authors have not covered more on the types of activities captured in the datasets, and their importance in smart homes, particularly from the perspective of occupant comfort and energy efficiency.
2. The number of sensors used to collect data seems a lot. In practice, its not practical to have so many sensors in a home collecting information. The authors should try some benchmarking on a subset of sensors if the dataset permits.
3. How will a sensor fusion approach work in this scenario?
4. What are the motivations behind hierarchical approach?
5. For Milan and Cairo, the temporal method might not be effective since the number of days in the experiment is less.
