data.csv is a 4-order tensor. The file has five columns. Each row is a non-zero entry of the tensor. Each of the first four columns has "item" ID of the dimension/order. The last column is the value of the entry.

For example, suppose we have 100 users, 50 movies, 10 websites, and 24 hours (each is a dimension), a row "34 12 4 5 5.0" means the User34 gives rating 5.0 to Movie12 on Website4 at Hour5.
