Characterizing Inverse Time Dependency in Multi-class Learning
multi-class learning large-scale classification supervised
2012/12/4
The training time of most learning algorithms increases as the size of training data increases. Yet, recent advances in linear binary SVM and LR challenge this commonsense by proposing an inverse depe...

Simple stochastic game Subexponential algorithm
2012/12/3
We study the problem of solving simple stochastic games, and give both an interesting new algorithm and a hardness result. We show a reduction from fine
approximation of simple stochastic games to co...
New approximations for minimum-weighted dominating sets and minimum-weighted connected dominating sets on unit disk graphs
Minimum-weighted dominating set Minimum-weighted connected dominating
2012/12/3
Given a node-weighted graph, the minimum-weighted dominating set (MWDS) problem is to find a minimum-weighted vertex subset such that, for any vertex, it is contained in this subset or it has a neighb...
最小二乘双胞支持向量回归机的研究
最小二乘支持向量机 支持向量回归机 双胞支持向量回归机
2012/11/7
利用最小二乘方法和临近支持向量机(PSVM)算法,并结合双胞支持向量机(TSVR),提出了最小二乘双胞支持向量回归机(LSTSVR).作为对照,TSVR需要求解2个二次规划问题,而LSTSVR仅需求解2个线性方程组.最后利用不同的实例验证了所提算法的可行性和有效性.
This paper provides a full geometric development of a new technique called un-reduction, for dealing with dynamics and optimal control problems posed on spaces that are unwieldy for numerical implemen...

2011/2/23
This paper develops an analytical relation on probability to obtain a condition on stability of steady states of open systems which represents the condition of quasi-ergodicity for the open systems to...
Properties of Conditional Expectation Operators and Sufficient Subfields
Conditional Expectation Sufficient Subfields
2010/11/24
We discuss some properties of conditional expectation operators, and use these facts to prove an interesting counterexample regarding sufficient statistics. In particular, we show that there exists su...
We present asymptotic and finite-sample results on the use of single-membership stochastic blockmodels for the analysis of network data. We show that the fraction of misclassified network nodes conver...
Secure Communication over Parallel Relay Channel
Secure Communication Parallel Relay Channel
2010/11/15
We investigate the problem of secure communication over the parallel relay channel in the presence of a passive eavesdropper. We consider a four terminal relay-eavesdropper channel which consists of m...
We study the model theory of covers of groups definable in o-minimal structures. This includes the case of covers of compact real Lie groups. In particular we study categoricity questions, pointing ou...
Ideal games, Ramsey sets and the Frechet-Urysohn property
Semiselective coideal Ramsey theory Frechet-Urysohn property
2010/12/8
It is shown that Matet’s characterization ([8]) of H-Ramseyness relative to a selec-tive coideal H, in terms of games of Kastanas ([5]), still holds if we consider semiselec-tivity ([2]) instead of se...

2010/12/3
The Springer numbers are defined in connection with the irreducible root systems of type Bn, which also arise as the generalized Euler and class numbers introduced by Shanks. Combinatorial interpretat...
