WebConsider the above sentence, we could assign 1 to “cat”, 2 to “mat”, and so on. We could then encode the sentence “The cat sat on the mat” as a vector like [5, 1, 4, 3, 5, 2]. This approach is efficient. Instead of a sparse vector, we now have a dense one vector (where all elements are full). There are two drawbacks to this approach. WebThe sparse vector technique operates on a stream of sensitivity-1 queries over a dataset; it releases the identity of the first query in the stream which passes a test, and nothing … do lice die in chlorine water

http://proceedings.mlr.press/v134/kaplan21a.html WebAn important observation in the ultra-reliable and low latency communications is that the size of transmit information is tiny. To support the effective short packet transmission, a sparse vector coding (SVC) scheme where an information is encoded into the positions of the sparse vector was proposed. In this paper, we propose a novel SVC technique further …
