EfficientDet was open sourced March 18 [1], YOLOv4 came out April 23 [2], and now YOLOv5 is out only 48 days later. In our initial look, YOLOv5 is 180% faster, 88% smaller, similarly accurate, and easier to use (native to PyTorch rather thank Darknet) than YOLOv4.

Those numbers are quite impressive. YOLOv4 -> YOLOv5 Inference time: 20ms -> 7ms (on P100) Frames per second: 50 -> 140 Size: 244mb -> 27 mb

f(x)=c, zero size, infinite fps. You should also take some accuracy metric into account ;)

Just recently IBM announced with a loud PR move that the company is getting out of the face recognition business. Guess what? Wall Street doesn't want to keep subsidizing IBM's subpar face recognition technology when open source and Google solutions are pushing the state of the art.

Not something to brag about. Facial recognition has very few applications outside of total surveillance. We should not respect those who lend it their time and effort.

Er so this "Ultralytics" consulting firm just borrowed the name YOLO for this model and didn't actually publish their results yet?

I'm a bit fascinated by this Ultralytics. It has super nice website but according to LinkedIn, I think it's just one guy who does consultancy.

The intriguing part is that he has also done research in particle physics (as Ulatrlytics) that has been published in Nature [1].

I had never seen anything like that.

We made a site that lets you collaboratively tag a bunch of images, called tagpls.com. For example, users decided to re-tag imagenet for fun: https://twitter.com/theshawwn/status/1262535747975868418

And the tags ended up being hilarious: https://pbs.twimg.com/media/EYXRzDAUwAMjXIG?format=jpg&name=...

(I'm particularly fond of https://i.imgur.com/ZMz2yUc.png)

The data is freely available via API: https://www.tagpls.com/tags/imagenet2012validation.json

It exports the data in yolo format (e.g. it has coordinates in yolo's [0..1] range), so it's straightforward to spit it out to disk and start a yolo training run on it.

Gwern recently used tagpls to train an anime hand detector model: https://www.reddit.com/r/AnimeResearch/comments/gmcdkw/help_...

People seem willing to tag things for free, mostly for the novelty of it.

The NSFW tags ended up being shockingly high quality, especially in certain niches: https://twitter.com/theshawwn/status/1270624312769130498

I don't think we could've paid human labelers to create tags that thorough or accurate.

All the tags for all experiments can be grabbed via https://www.tagpls.com/tags.json, so over time we hope the site will become more and more valuable to the ML community.

tagpls went from 50 users to 2,096 in the past three weeks. The database size also went from 200KB a few weeks ago to 1MB a week ago and 2MB today. I don't know why it's becoming popular, but it seems to be.

I thought the real focus on the bad actors at this point was on gait detection. Works in civil unrest situations where everyone covers their face.

Not the the difference matters that much.
