Given a stream of elements of the form $(i,\delta)$ where $i\in [n]$ and $\delta\in \{-1,1\}$ define the frequency of an element to be $f_i=\sum_{(i,\delta)} \delta$. We wish to find estimates $\hat{f}_i$ for each $f_i$ such that | Given a stream of elements of the form $(i,\delta)$ where $i\in [n]$ and $\delta\in \{-1,1\}$ define the frequency of an element to be $f_i=\sum_{(i,\delta)} \delta$.
