this is part of the wish to get sklearn into the system, which would give us a much better system to swap out different algorithms that may be better at doing this kind of thing
2019-03-12 07102, 2019
alastairp
but there are other ideas, like instead of doing 1 classifier for 15 classes, do 15 "yes"/"no" classifiers
2019-03-12 07129, 2019
reosarevok
Yeah, I remember studying that :D
2019-03-12 07135, 2019
alastairp
there was a participant in one of our challenges a few years ago who did subgenre classifiers
2019-03-12 07141, 2019
reosarevok
It does seem more relevant to how genre works
2019-03-12 07154, 2019
alastairp
so they had 1 to say "it's one of these 10 main genres", and then another for each genre to say "it's this subgenre"
2019-03-12 07102, 2019
alastairp
working out to combine them is a bit more complex though
2019-03-12 07125, 2019
alastairp
also, because a 600-class classifier is a bit shit
2019-03-12 07141, 2019
reosarevok
I mean
2019-03-12 07151, 2019
reosarevok
You could do it in two steps, but not limit it to one main genre
2019-03-12 07151, 2019
alastairp
also, because genre is a bit shit
2019-03-12 07155, 2019
alastairp
is that what you want to say?
2019-03-12 07156, 2019
reosarevok
haha. That it is
2019-03-12 07103, 2019
amCap1712
outsidecontext: once tagger is set up
2019-03-12 07126, 2019
alastairp
but yeah, lots of ideas, and if I had the time to get a better ML framework in place we could try many of them
2019-03-12 07132, 2019
reosarevok
But still. If you run it for each main genre, then pick any where yes P is bigger than X and then run the subgenre classifiers for *those* only, it's a bit less shit :)
2019-03-12 07141, 2019
alastairp
right
2019-03-12 07104, 2019
alastairp
the concern is, if the main classifier gets it really wrong, then the subclassifer is a bit of a moot point
2019-03-12 07110, 2019
reosarevok
Sure
2019-03-12 07123, 2019
reosarevok
But then you should realize by seeing the subclassifiers are all like "wait wat"
2019-03-12 07131, 2019
alastairp
actually getting an evaluation for a model is pretty cheap though... there's no reason to not run it on _all_ subclassifiers
2019-03-12 07109, 2019
alastairp
and then use that to say "these sub-cls really strongly thought it was a particular subgenre, let's see if the main genre one picks one of these ones as the top probability"
2019-03-12 07125, 2019
reosarevok
I feel the main problem for subclassifiers would just be how similar many would be, so that you'd be struggling to find enough data to differentiate them without overfitting
2019-03-12 07117, 2019
alastairp
and then working out what defines a subgenre, and if it makes sense to put it as a subgenre of genre x, given the features that are being used to discriminate it
2019-03-12 07142, 2019
alastairp
pulkit6559: that's not super important... maybe we might decide to do it after each class in a dataset has at least 10 example, or 100
Just reached room from lab. I will start with server and get back to you.

uh oh. too much time hacking on open source stuff?

Not premium.

Yes. I almost consume everyday in open source
2019-03-12 07126, 2019

are you familiar with "daily mixes" ?
2019-03-12 07129, 2019

Have bunked a hell lot of classes. Attendance is short.

Ma'am told me today. Leave it.
2019-03-12 07142, 2019

Yes.
2019-03-12 07153, 2019
ruaok
tsk tsk. uni is more important than open source. please stay on top of your classes!
2019-03-12 07156, 2019
pristine--
We should build playlist?
2019-03-12 07120, 2019
pristine--
Like daily mixes
2019-03-12 07132, 2019
ruaok
yes.
2019-03-12 07155, 2019
ruaok
because the features of "make me a playlist, LB" doesn't fit into our systems very well.
2019-03-12 07114, 2019
ruaok
however, making daily mixes for people is much easier.
2019-03-12 07120, 2019
ruaok
interstingly enough.
2019-03-12 07131, 2019
ruaok
we can re-use some code bits to make this happen.
2019-03-12 07140, 2019
pristine--
Daily mixes also require history of users, right?
2019-03-12 07148, 2019
ruaok
you know how the user reports get automatically refreshed when the user logged in the last month?
2019-03-12 07151, 2019
pristine--
I mean they are not just tope trending
2019-03-12 07156, 2019
ruaok
yes, correct.
2019-03-12 07159, 2019

Spotify broken for others too?
2019-03-12 07114, 2019
ruaok
unlink and relink, reosarevok.
2019-03-12 07121, 2019
reosarevok
No, no, not in LB, in general
2019-03-12 07123, 2019
pristine--
No. Not about this automatically refreshed.
2019-03-12 07137, 2019

reosarevok: relink the matrix then. man ld
2019-03-12 07152, 2019
pristine--
What is this last month thing.
2019-03-12 07158, 2019
ruaok
don't worry about it.
2019-03-12 07111, 2019
ruaok
I'll make it clear in a sec.
2019-03-12 07132, 2019
ruaok
so, if a user has enough listens and was active in a day, we can create a daily mix for the user.
2019-03-12 07142, 2019
ruaok
automatically at midnight or something like that.
2019-03-12 07101, 2019
ruaok
the main server requests it for the user and the mixes get created in a batch.
2019-03-12 07117, 2019
ruaok
and then they get sent back to the main server.
2019-03-12 07126, 2019
ruaok
and like the reports, the main server stores that info for the user.
2019-03-12 07139, 2019
ruaok
and if the user listens to their daily mix, we'll make another one for them tomorrow.
2019-03-12 07146, 2019
ruaok
if they don't we won't bother updating it.
2019-03-12 07119, 2019
ruaok
and I think we make daily mixes out of the collaborative filtering stuff you're building.
2019-03-12 07123, 2019
ruaok
with me so far?
2019-03-12 07104, 2019
pristine--
Yes
2019-03-12 07130, 2019
ruaok
so, I propose that this ought to be the plan for the summer.
2019-03-12 07140, 2019
ruaok
and thus the heart of your gsoc proposal.
2019-03-12 07110, 2019

Okay.
2019-03-12 07114, 2019

2019-03-12 07125, 2019

I use Google docs?
2019-03-12 07148, 2019
ruaok
and for a bonus, if you have time, we'll create discover weekly. 🤣
2019-03-12 07104, 2019
ruaok
yes, google docs is great for this.
2019-03-12 07109, 2019

Lol. Sure.

Have you ever got 9/20?

gr0uch0mars: Thats fine but the problem is that there is no efficient way of using a viewmodel inside the activity. We need to pass in a context and that will result in memory leaks. So the repository should directly return the data to the acitvity.
2019-03-12 07105, 2019

I went back and cleaned up all my bad grades, except calculus 1. I understood it, but the teacher didnt give any partial credit.
2019-03-12 07114, 2019

I understood the material, so I let the D stand.
