Thanks for pointing the missing glyph. I will paste the correct code.
backbias←{+/,⍵}
logistic←{÷1+*-⍵}
maxpos←{(,⍵)⍳⌈/,⍵}
backavgpool←{2⌿2/⍵÷4}⍤2
meansqerr←{÷∘2+/,(⍺-⍵)*2}
avgpool←{÷∘4{+/,⍵}⌺(2 2⍴2)⍤2⊢⍵}
conv←{s←1+(⍴⍵)-⍴⍺⋄⊃+/,⍺×(⍳⍴⍺){s↑⍺↓⍵}¨⊂⍵}
backin←{(d w in)←⍵⋄⊃+/,w{(⍴in)↑(-⍵+⍴d)↑⍺×d}¨⍳⍴w}
multiconv←{(a ws bs)←⍵⋄bs{⍺+⍵ conv a}⍤(0,(⍴⍴a))⊢ws}Comment · 2 years ago

I like the 19/20 French system.
Numberphile has a nice video about it: https://www.youtube.com/watch?v=QzrRkhU248A

Google spreadsheets have been neglected for a long time.
The sad part is that if this new project succeeded, it could catch google's attention and they will be able to launch a better version in a very short time.
They have too much power to strangle/buy any innovation. Just to let them die.
This is why I don't like google anymore.
