This is nice :) Kudos to the Youtube guys for releasing this. I'm a data scientist in a startup where one of the things I do is create multi-label models for classifying YouTube videos. My current model has 90 % precision and 69 % recall, while Youtube-8M has 78 % precision and 14 % recall, with respect to the human raters. I guess one of the reasons is that my model only has around 100 categories, while Youtube-8M has 4800. It's like comparing apples with pears, but still interesting.

#12How good do labels need to be for you to be able to get good results on something like this? There's a lot of data, so that's great, but the labels seem a bit spotty.

#13This is wonderful. Though I was wish i could just specify columns that I need and download those. Or limit number of rows. 1.5 TB is quite a bit. Regardless, this is wonderful. Would I be violating any law, copyright if I formatted it and put it on my server for that kind of consumption or via JSON?
The 1.5 TB is just for 1024 (8 bit each) dimension feature vectors for 1 frame per second on first 300 seconds of 5 Million videos.
You can actually download each shard (~300 Mb) separately. They haven't yet released the PCA matrix and quantization parameters used with inception model, but should release them soon.

#14Earlier quoted context omitted.
Get back to us when A.I reaches that of a cockroach.
That would actually be pretty frighteningly advanced. Cockroaches seem to understand a lot more about their environment than AI's do at the best of times, and they run a lot of different and diverse "programs".
I think we can probably write a cockroach simulator that would pass a "cockroach turing test". Cockroaches aren't magic, it'd be simple heuristics to emulate something that'd pass as a cockroach to an average person. And with expert domain specific knowledge on cockroaches, we could probably build something sophisticated and very cockroach like.
BTW, I'd like anyone to find me a cockroach that can beat Lee Sedol at Go.

By the same token, show me the computer that beat Lee Sedol find food, avoid poison and predators, seek a mate, etc. We're not bad at creating highly specialized AI, we seem to suck at creating competent generalists.

#16If, for some reason, you wanted a list of all of the video IDs (I couldn't easily find such a list), then I wrote a crappy scraper to pull them out: https://gist.github.com/JosephRedfern/d60bdc584d84b1451cc605....
I can post a URL to the output once it's finished running, if it'd be of any use to anyone. Oh, and be warned, there's a strong chance that it's buggy. It's certainly not optimised (no threads).
EDIT: The script has now run. I've scraped ~10,000,000 Video IDs, but only ~5.5m of these IDs are unique, so there's probably a bug in my script somewhere (but I need sleep now). Files containing IDs for various categories are listed here: https://redfern.me/public/yt8m/, some notes are here: https://redfern.me/public/yt8m/README.md, and .tar.gz'd archive is available here: https://redfern.me/public/yt8m/yt8m-ids-probably-incomplete.....

I'd love a list of IDs - I'm doing a research project that is a search engine for lectures (https://www.findlectures.com) and I'm interested to see if there is any overlap.
It seems like it'd be interesting to explore their tagging compared to what is in video transcripts.

#18Oh man. I am searching (thrashing) around for my next "big" project. i have been thinking of drones measuring roof / building quality and the CV/ML requirements are fairly high - getting my teeth stuck into these would really give me a better feel for training my own system. The problem is, how do I feed my family while taking the six months to do it all?
If you're serious about this concept, create a drone company that takes real estate photos. That will give you hands on experience with the regulations, quality control issues, etc while giving you time to build up your training set.
Hmmm ...
