How does Twitter use machine learning? by Arindam Paul

Answer by Arindam Paul:

I do not work on Twitter so I cannot deterministically answer this. I hope someone from Twitter answer this. However, as a person researching in machine learning, I can try to guess. Although I think they do not use it as much as Facebook or Google does as there is not much moderation or ranking going on.

  1. Trending: So twitter has this thing at the right (at least on my chrome desktop browser). You can see that what trends does not depend on what has the highest tweets right. So, I presume they use some machine learning to automatically learn the time-series data (tweets)

2. Moments: This is where there is not much difference between Twitter and a news website like Times. I believe (again I do not work at Twitter) that there is some kind of ML and heuristic algorithm which determines what pops up as Moments. One parameter which is definitely used is location.

3. Who to Follow: Again this uses information about the things you post (textual information, hashtags) , people following you, people recenty followed by you, people whose posts you favorited.

Also, I know for sure lot of people use twitter data for machine learning. I guess most of you knew this already. I had worked on a course project where I looked at "I just bought" tweets when people buy things from Amazon.

One arena where they do not use machine learning is modulate people's feed. So Twitter does not organize the feeds based on who you recently followed, who responds to your tweets etc.

V: Voilà! In view, a humble vaudevillian veteran cast vicariously as both victim and villain by the vicissitudes of Fate. This visage, no mere veneer of vanity, is a vestige of the vox populi, now vacant, vanished. However, this valourous visitation of a bygone vexation stands vivified and has vowed to vanquish these venal and virulent vermin vanguarding vice and vouchsafing the violently vicious and voracious violation of volition! The only verdict is vengeance; a vendetta held as a votive, not in vain, for the value and veracity of such shall one day vindicate the vigilant and the virtuous. Verily, this vichyssoise of verbiage veers most verbose, so let me simply add that it's my very good honour to meet you and you may call me V.
