It was brought to my attention that gender information was not included in the family label information provided, which should have been. In response, we added another bundle structured the same way, except now with 2 additional files, mid_gender_lut.mat (which is same as mid_lut.mat, except with a 3rd column containing gender information) and mid_lut.csv (same as mid_gender_lut.mat, except CSV formatted).
We kept the old bundles there to avoid confusion and added the new labels as traindata_updated.zip. Here is the link (https://1drv.ms/u/s!AkDk_XdBkJ9wgwx0bcRNBIv8vMET), which will be added under the "Get Data" tab as well.
I hope this helps!
Best regards,
Joe
