How do you use the Ratings to teach the Recommendations (Top Picks) Algorithm
Seems like I have destroyed any value in the recommendations engine, due to trying to improve it, by rating some of the recommendations. ie, like you would teach the watchworthy app.
I rated some older crime TV shows at a rating that was suitable at the time, eg, I rated a 30 yr old show perhaps a 7. Now, ALL the recommendations are for crime and comedy shows from 20-30 years ago ... pretty useless.
The algorithm seems to value ...
1. Because you watched this, then ....
BUT, there is no option to say I DIDN'T watch it and HAVE NO INTEREST in EVER watching it.
2. Rating of 7 seems to indicate you like this ...
WRONG! I liked it AT THE TIME. If I was rating it to indicate my preferences to wishing to watch similar shows NOW, then I would rate it only 1.
Anyone got any ideas how to use the rating system to get meaningful recommendations. Black box stuff is useless - valuable IP, my arse :) - no feedback or iteration = no improvement.
If nothing else, some sort of steer about the algorithm would be REALLY useful from IMDB, because at present, it's pretty useless.

When a title appears in a recommended list, it has a small "i" in a circle. If you click on that, you can click on a Not Interested icon.

Wonderful. Thanks for the info.
The "Not Interested" functionality doesn't seem to be in the web app, which is what I use by default.
IMDB need to add that functionality there and ...
Promote the information on the website/app, so that more people don't just click 1 to get rid of recommendations.
Other people have been caught out as well, and there was a full explanation provided in this response, but NO information added to the website / FAQ

I would like to understand better how the algorithm works.
I do not make heavy use of the recommendations, because I find it quite useless.
It seems to me that I can just find movies with actors and directors of my most recent ratings.
It doesn't really matter if you liked your most recent movies or not.
It's basically what you find in the "more like this" section in the title page of movies.
For instance, if you watch 3 movies of Rocky in a row and you don't like them at all (eg rating 4), you will still have other Rocky or Rambo movies.
But maybe I'm wrong.
