Reblog if you’re still seeing porn bots despite the NSFW ban. I’m still seeing them. Plenty of legitimate followers seem to be blocked from my feed, however.
*randomly materializes out of a murder of crows with a slurpee in my hand* hey guys what’s up?
*forty bats coalescing into an approximate human form, holding a gatorade* not much, how about you?
* 5 wolves make their presence known with a piercing how before joining in the circle. They clutter together, and take the form of a human with a iced coffee* ‘sup.
*emerges from the back exit of Dairy Queen to take out the garbage* uh.. uhhh.. m-my boss said y'all aren’t allowed to hang out back here…
I don’t mean to impose a personal favour on you guys, but I really would like to ask that everyonewho follows me reblog this.
I don’t think I made it very clear but last month I was sexually assaulted by someone who I thought was my friend (I don’t want to talk about it don’t ask), and it’s… really fucked with my head.
Had I known this a month ago I would have been able to get away.
So, essentially, I’m really pleading with you to reblog this so everyone who follows you doesn’t get stuck in the same position I was with no way out.
I mean again I don’t want the point of this to be my sob story or whatever but if you could reblog this it would seriously mean a lot
and im asking to all of my followers who see this post in your dashboard to please press play to this video, you never know when this is gonna be useful, PLEASE DON’T IGNORE IT.
This is one of the first moves I was taught in Krav Maga, and it is one of the most effective.
It took me about a half hour to get down with practice, but once you get it, it’s an intuitive movement.
Please pass this along, it will save lives.
Reblogging without all of the “you have to reblog this or you’re a bad person” and “I don’t care if this doesn’t match your theme” comments because no one should feel pressured to post anything, but I do think this is an important video to watch
Anonymous said: Once, I encountered the funny story of an AI image descriptor with a sheep obsession. It had been trained on pictures of fields of sheep. Therefore, it tagged anything in a field as 'sheep', including an empty field, because they work on statistical probability. Therefore, it thinks "ah, a field! there's probably a sheep here." (It's a bit more complicated but basically that.) It also couldn't recognise sheep in places that weren't fields, such as petrol stations or barns. [cont]
Now, the alarming aspect of this story is that the very same technology is probably what tumblr is using to identify porn. Now, if it can’t tell that an empty field is not, in fact, full of sheep, what hope do we have that it can’t tell an empty room isn’t full of writing human forms engaged in passionate coitus?
this really does sound like an episode of black mirror
This is gonna produce some absolutely baffling pornography.
…. oh my fucking god they actually are using open source software. They’re using a fucking one-layer unidirectional bicategory tag-trained neural network. This will never work. Literally, it will never work. There’s just not enough algorithmic complexity to do what they’re asking of it. I bet you I could prove on a mathematical level that this joke of a neural net fundamentally lacks the abstraction necessary to do its job.
This will never get better. Their algorithm will never stop fucking up, it will never actually flag porn reliably and it will always require a massive quantity of human hours to deal with the deluge of mistagged pictures. This isn’t just a case of an insufficiently trained algorithm, it’s just … this is the most basic neural network you can make. It probably hasa a lot of neurons and has loads of training data but like … you can’t just brute force this kind of stuff. One layer of neurons is just Not Enough.
Also, just to make this clear, Tumblr lied. I mean, we already know this, but I mean they liiiieeeeed. All that stuff they promised about what would or would not be censored? That cannot be delivered on with a system this simple. Nude classical sculptures, political protests, male-presenting nipples (really Tumblr?), nude art outside the context of sex, all that? You cannot train a bicategory one-layer neural network to exclude those things. It cannot be done. Tumblr never intended for those things to actually be permitted, they were just lying. Because the system they have cannot actually do what they said it would and never will be able to.
Also, this kind of system is super vulnerable to counter-neural strategies. I bet you before the end of the month someone hooks up their own open source one layer bicategory neural network which puts an imperceptible (to humans) layer of patterned static over arbitrary images, and trains it by having it bot-post static-ed images to Tumblr and reinforcing based on whether the images are labeled nsfw or sfw. Seriously, within a month someone will have an input-output machine which can turn any image ‘sfw’ in Tumblr’s eyes.
This is genuinely pathetic. Like, I have real pity for whoever implemented this, because it’s clear Tumblr doesn’t actually have any engineers with any expertise with machine learning left at all and they foisted the job off on some poor bastard who has no idea what they’re doing and is going to get all kinds of flak for their (perfectly reasonable and predetermined) failure from management.
