Anyone who actually uses Twitter already knows the algorithm:
* Chronological - reverse sort by date
* Home - for all of the followed topics, recommended topics, retweets and tweets in the past day determine the estimated level of engagement, include the highest and reverse sort by date. This is likely to be a fairly basic ML model.
It will be uncontroversial, technically unsophisticated and of no practical use to anyone - users, developers or researchers.
This is not going to be PageRank where some genuine new insight was discovered.
- tomcam 5y agoYou forgot the gigantic amount of human intervention required to unperson people who tweet against Twitter‘s political interests
- root_axis 5y agoWhat does "unperson" mean?
- LegitShady 5y agoit comes from Orwell's 1984 - someone who has been removed from all records/books/photographs and killed. I don't think the kill part applies here.
- bigfudge 5y agoIt’s lazy shorthand for “belatedly apply their policies against hate speech to prominent politicians”.
- tomcam 5y agoLike PewDiePie, Azealia Banks, Babylon Bee, and Carpe Donktum? By the way, in the USA there is no legal support for the term hate speech. It is covered under the umbrella of the first amendment.
- bigfudge 5y agoNo, pewdiepie was banned for five minutes for saying he was going to join isis. He’s still on the site but doesn’t tweet. https://mobile.twitter.com/pewdiepie https://mobile.twitter.com/pewdiepie Hate speech doesn’t need legal protection as a term to be against the rules of the site. I can’t remember if that’s the actual term twitter uses, but it’s the spirit of their rules. We could have a wider debate about whether our public square should be privately owned (I don’t think it should) but that wasn’t your point. Edit: more details and reason why his tweets are (self)deleted https://www.bbc.com/news/newsbeat-37244296 https://www.bbc.com/news/newsbeat-37244296
- tomcam 5y agoI brought up the first amendment because Elon has pretty much said that that is how they will decide on what continent gets published. I never came close to saying they don’t have the right to restrict speech anyway they wish
- tomcam 5y ago* content not continent. Apparently I am suffering from literary incontinence
- whimsicalism 5y agoWhat are you basing this on? I wouldn't assume response prediction is using a "fairly basic ML model," it can be a lot more than that.
- threeseed 5y agoIf it's a simple, constrained problem where the number of available features is low then inherently the complexity can never be high. I've built hundreds of models and run a ML company and I don't believe it's technically possible for this rule not to be the case.
- whimsicalism 5y agoI work in basically this field. Tweets have text and often images and users with relationships with other users posting and liking them, the potential feature space was never going to be low dimensional.
