Boosted Varying-Coefficient Regression Models for Product Demand Prediction
Boosting gradient descent tree-based regression varying-coefficient model
2015/8/21
Estimating the aggregated market demand for a product in a dynamic market is critical to manufacturers and retailers. Motivated by the need for a statistical demand prediction model for laptop pricing...
A limit theorem for scaled eigenvectors of random dot product graphs
limit theorem scaled eigenvectors random dot product graphs
2013/6/14
We prove a central limit theorem for the components of the largest eigenvector of the adjacency matrix of a one-dimensional random dot product graph whose true latent positions are unknown. In particu...
Interpreting Graph Cuts as a Max-Product Algorithm
Max-Product Interpreting Graph binary variable models
2011/6/16
The maximum a posteriori (MAP) con guration
of binary variable models with submodular
graph-structured energy functions
can be found eciently and exactly by graph
cuts. Max-product belief propaga...
Product-limit estimators of the gap time distribution of a renewal process under different sampling patterns
Kaplan-Meier estimator Cox-Vardi estimator Laslett's line segment problem nonparametric maximum likelihood Markov process
2010/3/11
Nonparametric estimation of the gap time distribution in a simple re-
newal process may be considered a problem in survival analysis under
particular sampling frames corresponding to how the renewal...
On Beta-Product Convolutions
Weyl fractional-order integral operator Williamson d-transform random scaling weighted Dirichlet distribution elliptical distribution
2010/3/9
Let R be a positive random variable independent of S which is beta distributed. In this paper we
are interested on the relation between the distribution function of R and that of RS. For this model w...

2009/9/24
This paper defines a class of univariate product partition models for
which a novel deterministic search algorithm is guaranteed to find the maximum
aposteriori (MAP)clustering or the maximum likeli...

Absolute continuity, quadratic forms, and causal perturbations of product measures
Absolute continuity of measures quadratic forms stable random variables
2009/9/22
Necessary and sullicient conditions are given for the
absolute continuity of a causally perturbed product measure with respect
to the non-perturbed measure. When the perturbation ia linear,
these c...

Product Screening to Multicustomer Preferences: Multiresponse Unreplicated Nested Super-ranking
Multicustomer Preferences Super-ranking Product
2009/9/3
Modern production methods demand the synchronous multicharacteristic optimization of goods. There is a need to diversify a basic product to the importance placed on its individual quality components b...
Transportation Approach to Some Concentration Inequalities in Product Spaces
Concentration Inequalities Product Spaces Transportation
2009/5/12
Let P be any product (Borel) probability measure on product (Polish) space E and for vectors x,y,z in E let f(x,y,z) be the number of coordinates k for which x_k neither equals y_k nor z_k. Using a tr...
A note on the invariance principle of the product of sums of random variables
central limit theorem invariance principle random variables
2009/3/23
The central limit theorem for the product of sums of various random variables has been studied in a variety of settings. The purpose of this note is to show that this kind of result is a corollary of ...
Markov processes with product-form stationary distribution
Markov process stationary distribution
2009/3/23
We consider a continuous time Markov process (X,L), where X jumps between a finite number of states and L is a piecewise linear process with state space Rd. The process L represents an “inert drift” o...
Threshold phenomena on product spaces：BKKKL revisited（once more）
Threshold phenomena product spaces
2009/3/19
We revisit the work of Bourgain et al. (1992) -- referred to as ``BKKKL'' in the title -- about influences on Boolean functions in order to give a precise statement of threshold phenomenon on the prod...
