I find it very interesting that Twitter recommends relevant tweets to me, but the topic suggestion is completely off. It looks to me like the recommendation and topic selection algorithm are completely different.
While the tweet recommendation algo is more sophisticated that likely takes into consideration the semantic content of the tweet, the topic selection algo seems to be a simple algorithm that heavily weighs the presence of keywords.
As another example, this tweet originally came up on my feed under the topic of "Interior design"
Saw few tweets on pigeon-based classification of breast cancer (@tunguz@hardmaru, @Dominic1King, & ML Reddit), which was published in 2015. I work with the legend himself @rml52! I thought for my 1st Twitter thread I'd go over the papers's main points & our current work! (1/11)
My PI often likes to say AI stands for avian intelligence. And indeed his paper shows pigeons can learn the difficult task of classifying the presence of breast cancer in histopathological images. (2/11)
The pigeons were placed in an apparatus and the 🔬 image was shown to the pigeons on a touchscreen. The pigeons were given food if they pressed the correct button on the screen. (This is opposed to regular pathologists who are not given free food when analyzing images!) (3/11)
