I had presented the “Ethics and Data Science” materials to my research group today, a 30 people data visualization group at HKUST! It was an underdiscussed issue, but not anymore! Thank you, @jeremy and @rachel !

Here is my slides, copied and annotated the original course slides on Github.

@Jdemlow

I’m facing the same issue but couldn’t able to solve it.
After looking into forums i ran this conda install -c defaults intel-openmp -f but nothing happend & also i don’t know what’s the significance of it.

Have you solved it? Can you please help me.

Thanks,
Sumit

yes , its the same … I later realized that feature logic is not working in my system now sure why .


(Sumit) #712

Can you tell what’s the shape of df and y?
& what’s showing after you run proc_df , I mean any error or anything which will be helpful to figure what’s wrong ?

and also if at all df & y has values then can you post first 4-5 rows in here .

Thanks,
Sumit

Hi Jeremy since these videos are not to be found on courses.fast.ai and only on youtube am I right in presuming that they have not been formally launched as of yet for the ML course


(Yoong Kang Lim) #718

Hey everyone! First post here.

In the video for lesson 7, about 18 minutes in @jeremy makes a point about imbalanced datasets. He mentioned a recent paper that looked at some approaches to deal with this and concluded that oversampling from the smaller category wins out consistently.

Has anyone tracked down this paper? I’d love to have a look at it.
