Dear Andreas, Thanks a lot for your help,
about the random assignment of values to my labels y. What I mean is that being suspicious about the too good performances, I changed the labels manually, retaining the 50% 1,0 but in different orders, and the labels were always predicted very well, with accuracy no lower than 60%. I mean, by chance I aspected values lower than 50% as well as values higher than 50%. I didn't perform an exhaustive test (I only did it manually for few combinations)...
