YouTube offers three new ways to enhance the experience of surfing the platform.
First, Google's own video service exposes topics and related videos on its home page and under the "top" tab. Second, users can remove suggestions from channels they do not want to see. Third, users get more information about why videos have been recommended to them.
With these changes, YouTube wants to give you control over what content appears on the site.
According to YouTube, topic options are based on existing personalized suggestions. However, they may refer to a video you are watching or to videos posted by that channel.  The "Do not recommend channel" option is technically not new. According to the YouTube support page, you can completely disable recommendations from specific channels by tapping "Not interested," then "TELL US WHY," and then "I'm not interested in this channel."
It also means that you can recommend a particular video based on what other viewers with similar interests have liked and viewed in the past – that's the way a collaborative filtering algorithm works. Spotify, Netflix, and Amazon are already using this technique to suggest songs, movie titles, and products you might like.
In recent years For months, the video platform has been criticized for not doing enough to address toxic videos on the platform. Between the allegation of radicalizing teens by putting down extremist rabbit holes and ignoring the harassment of LGBT creators, YouTube has seen that the algorithm recommends inappropriate videos to children, including explicit sexual language and jokes about pedophilia.
The development comes weeks after that began with the introduction of new measures against hate speech on the platform. Videos promoting the superiority of a group should be banned as justification for discriminating against others based on "age, gender, race, caste, religion, sexual orientation, or veteran status."
It's hard to judge if the changes have the desired effect. However, they are long overdue and will hopefully clean up the toxic recommender system.
Some features are now available worldwide in the YouTube app for Android and iOS, others are expected to be introduced to Android, iOS and iOS desktop in the coming days.
