error in fm_get_p function

[wsgtcyx]

Hi, I found that in the 51th line of your fm_parallel_sgd.scala file, the result of "val phi = 0.5*(VX:VX - VX_square).sum" and "val phi = 0.5(VX:*VX :- VX_square).sum" is different, which the second one should be right, described in original paper. please check. Thank you!
