Fusing Mobile Phone and Travel Survey Data to Model Urban Activity Dynamics

Algorithm 2

EM-based solution algorithm.

	Step 0: Let fill the missing values in with random values. Set .
	Step 1: Decompose tensor :
	And
	Step 2: Let fill the missing values in with values in .
	Step 3: Convergence check:
	If , terminate the algorithm, . Otherwise , go to Step 1.
