Approximation Algorithms for Free-Label Maximization
نویسندگان
چکیده
Inspired by applications where moving objects have to be labeled, we consider the following (static) point labeling problem: given a set P of n points in the plane and labels that are unit squares, place a label with each point in P in such a way that the number of free labels (labels not intersecting any other label) is maximized. We develop efficient constant-factor approximation algorithms for this problem, as well as PTASs, for various label-placement models.

متن کاملAn Exact Algorithm for F-Measure Maximization
The F-measure, originally introduced in information retrieval, is nowadays routinely used as a performance metric for problems such as binary classification, multi-label classification, and structured output prediction. Optimizing this measure remains a statistically and computationally challenging problem, since no closed-form maximizer exists. Current algorithms are approximate and typically ...
متن کاملStreaming Variational Inference for Dirichlet Process Mixtures
Bayesian nonparametric models are theoretically suitable to learn streaming data due to their complexity relaxation to the volume of observed data. However, most of the existing variational inference algorithms are not applicable to streaming applications since they require truncation on variational distributions. In this paper, we present two truncation-free variational algorithms, one for mix...
متن کاملBelief Propagation, Mean-field, and Bethe approximations
This chapter describes methods for estimating the marginals and maximum a posteriori (MAP) estimates of probability distributions defined over graphs by approximate methods including Mean Field Theory (MFT), variational methods, and belief propagation. These methods typically formulate this problem in terms of minimizing a free energy function of pseudomarginals. They differ by the design of th...
متن کاملEfficient Approximation Algorithms for Point-set Diameter in Higher Dimensions
We study the problem of computing the diameter of a set of $n$ points in $d$-dimensional Euclidean space for a fixed dimension $d$, and propose a new $(1+varepsilon)$-approximation algorithm with $O(n+ 1/varepsilon^{d-1})$ time and $O(n)$ space, where $0 < varepsilonleqslant 1$. We also show that the proposed algorithm can be modified to a $(1+O(varepsilon))$-approximation algorithm with $O(n+...
