WebThe Goldreich-Levin theorem says that one can decode the Hamming code locally, i.e., with only a few queries to the bits of the received string, without looking at it completely. Moreover, one can decode from 1 2 fraction of errors. Of course, this means that the decoded message is no longer unique. WebGoldreich,Rubinfeld and Sudan generalized the theorem: let $\mathbb{F}$ a field such that $ \mathbb{F} =poly(n)$ and let $f: \mathbb{F}^n\rightarrow\mathbb{F}^m$ a one-way … bird road animal clinic 147
