<BPlayer>
egg: "The first and immediate thing to catch the reader's eye is the coherence between [...]"
<egg>
SnoopJeDi: no, unmittelbar is immediately
<SnoopJeDi>
egg, oh yes I think I caught your meaning, I just decided I wanted to say "aha I see" in Spanish because distractionbrain is strong today
<egg>
SnoopJeDi: my msc thesis doesn't have any obvious or clear fwiw
<egg>
those are silly words
<egg>
it does have one immediate and two trivials,
<SnoopJeDi>
trivial I can live with
<egg>
(immediately actually)
<egg>
eggsactly an unmittelbar :_p
<SnoopJeDi>
I prefer to either not put a descriptor at all, or just describe directly the operation(s) to which I'm referring
<SnoopJeDi>
but sometimes it's just clumsier without it, yea
<SnoopJeDi>
I don't necessarily *treat* it like a syntax error, but a bright red background reminds me to check if I *really* want to say it that way
<egg>
SnoopJeDi: tbh I just dislike "obvious" as a word, it sounds less nice than "trivial", "immediate" etc.
<SnoopJeDi>
egg, I think the thing I don't like about "obvious" and "clear" is that it prescribes the reader's state of mind
<BPlayer>
Either of those sound discouraging to me if the thing in question is not evident at first
<SnoopJeDi>
I'm coming up with muddled results for poking around on scholar with queries for "es claro que" and the like, might ask my mx labmate

but tbf I'm also that guy who pokes Wikipedia and goes "ohhhhhhh L-systems are a superset of this class of fractals" despite being superficially acquainted with both long prior, so I think I'm on the wrong side of the bell curve wrt grammar 😅

hey I want to make a neural net train on images of speed signs to learn when a roadsign is a speed sign and then a separate network can grab the numbers from it, how hard would it be to do this?
<SilverFox>
is this sort of stuff something that takes a lot of time to implement, like months, excluding training time?
<e_14159_>
SilverFox: Do you have experience with neural networks?
<SilverFox>
none
<e_14159_>
Maybe a week or two.
<SilverFox>
okay that's not bad
<UmbralRaptop>
egg: for the record, e = 0, K=277.52, and this is around a 1.39 M_☉ star.
<e_14159_>
But you can directly classify speed limit including numbers.

!wpn
* Qboid
gives egg a neurosis which strongly resembles a vtable
<UmbralRaptop>
Uh, since I dropped units, K is in m/s
<SilverFox>
e_14159_, yeah but wouldn't that require me to just train with only 60km/h speedsigns, and then I'd haev to repeat for each speed limit?
<UmbralRaptop>
Qboid: that's mean
<SilverFox>
I want to explicitly train it on common ones, but have it able to just recognize speedsigns that it hasn't been trained on, like the 100km/h ones
<SilverFox>
on the 2 hour drive to my gf's place there's a fuckton of roadsigns, so I'd just tape a camera to the windshield of my car and manually press a button on my raspi that would take a burst of pictures
<SilverFox>
and then I'd use those pictures, crop em, and then train the system
<e_14159_>
Ah. Well, the main example I have is the German Traffic Sign Benchmark, which contains 50,000 pictures. It has 20, 30, 50, 60, 70, 80, 100, and 120km/h signs labeled.
<e_14159_>
For arbitrary speed limits, it's a bit more complicated; you can check out the Streetview House Numbers for inspiration
<SilverFox>
also, the speedlimit signs in canada are like, square
<SilverFox>
not the round circle ones
<SilverFox>
our signs are rectangular anyways
<e_14159_>
Ah, right. In that case, I'm not aware of pre-labeled datasets.
<SilverFox>
I'm fine with taking the pictures myself
<egg>
SilverFox: "which contains 50,000 pictures"
<e_14159_>
On the order of 10k images?
<SilverFox>
I predict my system can take an image at least every quarter of a second
<SilverFox>
so 4/second, so like, 20-30 images every sign
<UmbralRaptop>
I sense a problem with this dataset.
<SilverFox>
I can't train it on a dataset that's pristine and clear, because that's not real-world, I need it trained at an angle that my car would realistically see
<egg>
you'll be very good at recognizing the sign that you photographed dozens of times at least :-p
<SilverFox>
if it could take the pictures itself everytime it senses a "roadsign" then that'd be neat, save me some work while driving anyways, would still have to comb through them afterwards but whatevs
<e_14159_>
SilverFox: The issue is overfitting and amount of data. Probably, you need about 10k examples (more would be better). That's probably about 10-15 hours of labeling.
<SilverFox>
I'll also like some winter-time datasets as well
<SilverFox>
so this would be over the course of a few months
<SilverFox>
perhaps I'll train a stop sign recognition system with a more standard dataset, as a trial of how well it can perform real-world
<SilverFox>
would a 720p webcam be enough or should I go for a 1080p one?
<e_14159_>
Again, the main time-hog will be labeling - I could probably throw together a prototype for the NN as-is in a day.
<SilverFox>
what's included in the process of labelling?
<e_14159_>
But I can talk a bit more tomorrow - for now, I'll head to bed (have to be awake to be training neural networks tomorrow :-) )
<egg>
!wpn e_14159_

it's the one that fucks with spacing right?

<SilverFox>
would result in some stupid error or something?

Ada 2012 even has those
<egg>
(if condition then value_if_true else value_if_false)
<egg>
iirc
* egg

<SilverFox>
is there like, a way of visually representing a neural net learning?
<SilverFox>
I could make a twitch stream of it learning
<awang>
egg: What have you used Ada for?
<egg>
generating LEGO walls
<SilverFox>
is labelling a dataset tedious or something?
<SilverFox>
like just "this picture has a speed sign" and just repeat for each picture?
<SilverFox>
or is it more like "this area has the sign in it" ?
<SilverFox>
also, a monochrome image would be the best here, as colour is irrelevant
<SilverFox>
so I can reduce filesize by a good chunk, like 2/3rds?
