### Re: Grammar Time!

We have a matrix of data X and an outcome variable Y, which could be discrete or continuous.
The matrix? The outcome variable? Both? What can be either discrete or continuous?

It's ambiguous and therefore sloppy.

Clarity would force a change to the writing:
"...both which can be...."
"...the later which can be...."
"...the former which can be...."

Ambiguity does have its uses.

There are two kinds of people: digital and analog. It's a kind of Sapir-Whorf.

e.g. in maths you are good in algebra or analysis.

"We have a matrix of data X and an outcome variable Y, which could be gigabytes in size."

"We have a matrix of data X and an outcome variable Y, which could be derived from empirical results."

"We have a matrix of data X and an outcome variable Y, which has an associated utility function."

X, Y, or X&Y?

"We are all joined together as one American family and your suffering is our burden also, (...)"
Is that correct use of 'also'?

Not very popular in British English, but correct, IMHO. (see https://english.stackexchange.com/quest ... -with-also also [sic])

Off the top of your head, can you estimate how many frames a state of the art DQN needs to reach human performance?
How can one know ex ante a break is required after "needs"?

Red Cross reveals 21 staff paid for sexual services
does that mean that the staff are the ones paying for sexual services or the ones being paid for sexual services?

Depends on the context.
Grammatically, it could be an action verb. In the other case, we could remove the ambiguity by 'were paid'. (?)
