Sharp uniform convergence bounds through empirical centralization

no code implementations NeurIPS 2020 Cyrus Cousins, Matteo Riondato

We introduce the use of empirical centralization to derive novel practical, probabilistic, sample-dependent bounds to the Supremum Deviation (SD) of empirical means of functions in a family from their expectations.

MCRapper: Monte-Carlo Rademacher Averages for Poset Families and Approximate Pattern Mining

1 code implementation16 Jun 2020 Leonardo Pellegrina, Cyrus Cousins, Fabio Vandin, Matteo Riondato

To show the practical use of MCRapper, we employ it to develop an algorithm TFP-R for the task of True Frequent Pattern (TFP) mining.

TRIÈST: Counting Local and Global Triangles in Fully-dynamic Streams with Fixed Memory Size

1 code implementation24 Feb 2016 Lorenzo De Stefani, Alessandro Epasto, Matteo Riondato, Eli Upfal

We present TRI\`EST, a suite of one-pass streaming algorithms to compute unbiased, low-variance, high-quality approximations of the global and local (i. e., incident to each vertex) number of triangles in a fully-dynamic graph represented as an adversarial stream of edge insertions and deletions.

Finding the True Frequent Itemsets

no code implementations7 Jan 2013 Matteo Riondato, Fabio Vandin

It requires to identify all itemsets appearing in at least a fraction $\theta$ of a transactional dataset $\mathcal{D}$.
