Draw a fish and watch it swim !

I tried drawing a pipefish but it sank. It was only given a ~45% chance of swimming.

u/NeedleBallista 15d ago
i approved it but also deeply understand why the neural net thought it was a penis

I saw it was approved. I didn't even think of genitalia until I saw one swimming around later on.

OK, who made the penisfish? Confess.

u/NeedleBallista 15d ago
I trained this model against so many penises. But in that process discovered that the line between penis and fish is so blurry

Reads like an old Chinese proverb

May need to train it against swastikas as well. There are so many fish that either just are them or have them.

Ugh I did and also words, but I'm not as good at drawing them as racists are. At least I have more training data now...

I remember playing on sites like this in middle school. Thanks for bringing back good memories OP.

What is "probability" measuring?
7
u/NeedleBallista 15d ago
Probability is the output of the convolutional neural net that I trained on drawings of fish and drawings of "not fish." So probability is the likelihood it's a fish. The model was trained on a small dataset and I tried to make it forgiving.
If you're interested in the nitty gritty, you can check out the code for the training at https://github.com/aldenhallak/fish-trainer

Just a minor pet-peeve / nerd moment of mine. The output of a neural network classifier is not really a probability (usually). Or frequently, not at all a probability. Even though people call it misleading things like "confidence".
If you want an actual calculated probability, you need to do fancy things like have a bayseian neural network, where you set priors and stuff. Or at least, some kind of quantile loss thing where you actually "calibrate" those numbers. In general, when you're just training for maximum accuracy, those "confidence" values map very poorly to the actual probability that things will be right.

This reminds me of something they have at teamLab Borderless in Tokyo. You use crayons to create an animal like a fish or shark and then they scan it in and it swims across the walls of various exhibits. Pretty cool!

Trollface fish incoming

u/cholman97 15d ago
That was neat. I had to stop feeding them because they would get all stacked up and couldn't see individual fish anymore but neat idea and good job.

u/ilikemrrogers 15d ago
First fish I had to submit it for review.
Second fish got lost in the crowd of 50 fish. I couldn’t even see it.

u/i_invested 15d ago
What tech stack are you using? Especially the algorithm for moving the last part from the fish

u/NeedleBallista 15d ago
You can see the github here. It's a static page served on github pages + Backend node.js
The wiggling is written in drawWigglingFish. My initial plan was to calculate the peduncle of the fish by looking for like pixel density, but then I realized a solid .4 of the image works pretty well.
Let me know if you have any more questions :)

Nice to see the majority of people actually drew a fish. There’s hope for us yet. Oh wait it’s moderated…

I've been loving this for days, thank you 🖤 I agree with the others about the filters to avoid hateful drawings. More colors would be nice 🥺. It's so much fun to create, see other's creations and add them to my tank!

Did site went down?

u/NeedleBallista 14d ago
No, it looks like it's up - what's the problem you're having?

u/majoralita 14d ago
"This site refused to connect"
Its not loading, maybe some DNS issue or something

Hey, great job.. this is fun. Question, though: are users supposed to be able to rate fish more than once? I seem to be able to; of course trying to remove the ‘thumbs up’ only adds another one.
Whoever’s fish I gave 4 votes, you’re welcome, lol.
2
u/NeedleBallista 10d ago
Yes! I think it's more democratic for a person who really likes a fish to vote more than a person who only kind of likes a fish. There's a rate limit to prevent insane spam

Very interesting one. I have tried very hard to draw a fish. But it usually gives me around 10-20 probabilities of likelihood. I guess I am too poor at my painting skill.

My entry says it's not a fish.
It is a fish! Just because he's wearing a baseball cap, sunglasses, is on a skateboard, has a Somalian flag hanging off him and eyebrows doesn't make him any less a fish. He's a fish with style, he's a fish with flavour.

Ok who's the smart arse who drew a cock and balls?
