Data format

The file heat.csv contains the raw temperature data. The 200 rows correspond to the 200 timestep, and the 41 columns are the 41 space points. The file heat_relations.csv contains the spatial relation between the 41 space points. It is a 41 by 41 adjacency matrix A, where A(i, j) = 1 means that series i is a direct neighbor of series j in space, and is 0 otherwise.
