“…The initial policy d 1 is selected as a naive estimation, which increases the estimation when E C k = e 1 , reduces it when E C k = e 2 , and keeps it unchanged otherwise. This policy is popularly adopted in commercial sensing systems, but is known to have accumulative errors [33,34]. We consider five groups of experiments.…”

“…In this section, we derive an estimator of as a function of the measurements and and the estimated room dynamics , , . Let (10) and consider the levels prediction error (11) Under the stated assumptions is a zero-mean Gaussian white noise [41]. Substituting (10) into (11) and rearranging properly, we obtain (12) where the unknowns are only and , since can be computed given the available information.…”

“…When there are many occupants, the uncertainty of occupants' movement may have a great impact on building load. Based on our previous work in [14] and [15], we can use the statistical data from the RFID system to estimate the occupants' distribution in different buildings. Then scenario tree is also used to illustrate the uncertainty of occupants distribution in the following section.…”

“…There are 1000 occupants and their distribution is estimated as shown in Table. 1 (mainly based on students' activity). In our previous work [14] and [15], RFID system is used to estimate the occupants' distribution. The historical statistical data can be used to establish a more accurate distribution model.…”
