Sublime: Sublinear Error & Space for Unbounded Skewed Streams
Navid Eslami, Ioana O. Bercea, Rasmus Pagh +1
Modern stream processing systems often need to track the frequency of distinct keys in a data stream in real-time. Since maintaining exact counts can require a prohibitive amount o…
Algorithms for the Diverse-k-SAT problem: the geometry of satisfying assignments
Per Austrin, Ioana O. Bercea, Mayank Goswami +2
Given a -CNF formula and an integer , we study algorithms that obtain solutions to the formula that are maximally dispersed. For , the problem of computing the diame…
Hashing for Sampling-Based Estimation
Anders Aamand, Ioana O. Bercea, Jakob Bæk Tejs Houen +2
Hash-based sampling and estimation are common themes in computing. Using hashing for sampling gives us the coordination needed to compare samples from different sets. Hashing is al…
Aleph Filter: To Infinity in Constant Time
Niv Dayan, Ioana-Oriana Bercea, Rasmus Pagh
Filter data structures are widely used in various areas of computer science to answer approximate set-membership queries. In many applications, the data grows dynamically, requirin…
