Strategies for antigen testing: An alternative approach to widespread PCR testing
Reddy, S. G.; Das, S.
Show abstract
Multiple applications of low cost and rapid antigen tests for individuals, in parallel (at the same time) or at times sufficiently close to each other, when appropriately interpreted can considerably increase sensitivity of these tests, improving on their performance greatly. Under reasonable assumptions, this occurs when considering a positive to arise in a composite test if at least one of two underlying repeated tests are positive. Parallel Rapid Testing can potentially provide a form of testing that is accessible (combining wide availability and lack of expense) and quick. Moreover, it can provide a level of sensitivity that is comparable to seemingly more sophisticated but more expensive alternatives. In combination with sequential testing, this strategy offers an alternative method of testing that can be applied immediately and on a widespread basis.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
