Now we have it in sw we can display it easy enough:
sa: load the-doors--people-are-strange.sw sa: table[lyrics] lyrics-for |the doors: People are strange> +-------------------------------------------+ | lyrics | +-------------------------------------------+ | "People Are Strange" | | | | People are strange when you're a stranger | | Faces look ugly when you're alone | | Women seem wicked when you're unwanted | | Streets are uneven when you're down | | | | When you're strange | | Faces come out of the rain | | When you're strange | | No one remembers your name | | When you're strange | | When you're strange | | When you're strange | | | | People are strange when you're a stranger | | Faces look ugly when you're alone | | Women seem wicked when you're unwanted | | Streets are uneven when you're down | | | | When you're strange | | Faces come out of the rain | | When you're strange | | No one remembers your name | | When you're strange | | When you're strange | | When you're strange | | | | When you're strange | | Faces come out of the rain | | When you're strange | | No one remembers your name | | When you're strange | | When you're strange | | When you're strange | +-------------------------------------------+And we are done. All nice and pretty.
Update: say we want to pick a doors song randomly. That is easy enough. And say that we have weights that represent how much we like them. Maybe something like:
list-of-songs |The Doors> => 10|the doors: People are Strange> + 10|the doors: Light My Fire> + 7|the doors: The End> + 6|the doors: Love Me Two Times> + ... + 0.2|the doors: Moonlight Drive>Then simply enough:
sa: load the-doors.sw sa: table[lyrics] lyrics-for weighted-pick-elt list-of-songs |The Doors>And we need some mechanism to filter out songs we have recently heard, and longer term changes in weights for when we get bored of a song.
Maybe we need something along the lines of:
list-of-songs |heard recently> => |the doors: Light My Fire>
list-of-interesting |songs> => complement(list-of-songs |heard recently>,list-of-songs |The Doors>)
Though I don't yet have a complement function, but shouldn't be hard to write one.
Update: wrote a couple of lines of code, so we can now do this example (and it turns out I already had complement() defined in another way, so exclude() seemed the best name).
First the code tweaks (in the functions file):
# exclude(|a> + |c>,|a> + |b> + |c> + |d>) == |b> + |d>
#
def exclude_fn(x,y):
if x > 0:
return 0
return y
def exclude(one,two):
return intersection_fn(exclude_fn,one,two).drop()
Now put it to use:
sa: list-of-songs |The Doors> => 10|the doors: People are Strange> + 10|the doors: Light My Fire> + 7|the doors: The End> + 6|the doors: Love Me Two Times> + 0.2|the doors: Moonlight Drive> sa: list-of-songs |heard recently> => |the doors: Light My Fire> + |the doors: The End> sa: list-of-interesting |songs> => exclude(list-of-songs |heard recently>,list-of-songs |The Doors>) sa: list-of-interesting |songs> 10|the doors: People are Strange> + 6|the doors: Love Me Two Times> + 0.2|the doors: Moonlight Drive>It works! And this idea of "list-of-something |heard recently>" and then excluding it from a list, seems to me a common pattern humans use. Maybe something as simple as telling jokes. You want to keep track of the ones you have already said. And the reverse, dementia. You forget the stories you have just told to your grandchild. And the child says "Grandma, you already told me that one!".
In this case the child might be doing something like:
you-already-told-me-that-one |*> #=> do-you-know mbr(|_self>,list-of-stories|heard recently>)
The other thing about the exclude function, it reminds me of this Sherlock Holmes quote:
"Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth."
list-of |options> => exclude(list-of |impossible>,list-of-all |possible>)
And then the "no matter how improbable" means the highest coeff in "list-of |options>" is small. But, nonetheless, it is the best option left.
