CountSketches, Feature Hashing and the Median of Three

no code implementations3 Feb 2021 Kasper Green Larsen, Rasmus Pagh, Jakub Tětek

For $t > 1$, the estimator takes the median of $2t-1$ independent estimates, and the probability that the estimate is off by more than $2 \|v\|_2/\sqrt{s}$ is exponentially small in $t$.

Performance of Bounded-Rational Agents With the Ability to Self-Modify

no code implementations12 Nov 2020 Jakub Tětek, Marek Sklenka, Tomáš Gavenčiak

We show that this result is no longer true for agents with bounded rationality.

Sampling an Edge Uniformly in Sublinear Time

no code implementations23 Sep 2020 Jakub Tětek

We also note that sampling edges from a distribution sufficiently close to uniform is sufficient to be able to simulate sublinear algorithms that use the random edge queries while decreasing the success probability of the algorithm only by $o(1)$.
