Data Structures for Density Estimation [PDF]

open access: yesInternational Conference on Machine Learning, 2023
We study statistical/computational tradeoffs for the following density estimation problem: given $k$ distributions $v_1, \ldots, v_k$ over a discrete domain of size $n$, and sampling access to a distribution $p$, identify $v_i$ that is"close"to $p$.

Automated Dynamic Bayesian Networks for Predicting Acute Kidney Injury Before Onset [PDF]

open access: yesarXiv.org, 2023
Several algorithms for learning the structure of dynamic Bayesian networks (DBNs) require an a priori ordering of variables, which influences the determined graph topology. However, it is often unclear how to determine this order if feature importance is

Algorithms and Data Structures for Multi-Adaptive Time-Stepping [PDF]

open access: yesTOMS, 2008
Multi-adaptive Galerkin methods are extensions of the standard continuous and discontinuous Galerkin methods for the numerical solution of initial value problems for ordinary or partial differential equations.

The Euclid Algorithm is totally gaussian [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We consider Euclid’s gcd algorithm for two integers $(p, q)$ with $1 \leq p \leq q \leq N$, with the uniform distribution on input pairs. We study the distribution of the total cost of execution of the algorithm for an additive cost function $d$ on the ...

Why almost all satisfiable $k$-CNF formulas are easy [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
Finding a satisfying assignment for a $k$-CNF formula $(k \geq 3)$, assuming such exists, is a notoriously hard problem. In this work we consider the uniform distribution over satisfiable $k$-CNF formulas with a linear number of clauses (clause-variable ...

Boltzmann Oracle for Combinatorial Systems [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Boltzmann random generation applies to well-defined systems of recursive combinatorial equations. It relies on oracles giving values of the enumeration generating series inside their disk of convergence.

Generic properties of random subgroups of a free group for general distributions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We consider a generalization of the uniform word-based distribution for finitely generated subgroups of a free group. In our setting, the number of generators is not fixed, the length of each generator is determined by a random variable with some simple ...
