RGB vs all-one vector features #386

Should we expect to get better performance when add RGB as the feature in the sparse tensor? For my application, instead I found performance drop when using RGB ( I did normalize the values to [-0.5, 0.5] as shown in given examples). Any thoughts?

Have you ever solved this problem or figure anything out?
