Confidence Intervals for Random Forests:The Jackknife and the Infinitesimal Jackknife
bagging jackknife methods Monte Carlo noise variance estimation
2015/8/21
We study the variability of predictions made by bagged learners and random forests, and show how to estimate standard errors for these methods. Our work builds on variance estimates for bagging propos...
Infinitesimal Hopf algebras
Hopf algebras derivations Yang-Baxter equation Drinfeld’s double
2015/8/14
Infinitesimal bialgebras were introduced by Joni and Rota [J-R].
An infinitesimal bialgebra is at the same time an algebra and a coalgebra, in
such a way that the comultiplication is a derivation. I...

Infinitesimal bialgebras pre-Lie algebras dendriform algebras
2015/8/14
We introduce the categories of infinitesimal Hopf modules and bimodules over an infinitesimal
bialgebra. We show that they correspond to modules and bimodules over the infinitesimal
version of the d...
Infinitesimal variations of Hodge structure at infinity
Degradation hodge structure polarization polarization integrated hodge structure
2014/12/24
By analyzing the local and infinitesimal behavior of degenerating polarized variations of Hodge structure the notion of infinitesimal variation of Hodge structure at infinity is introduced. It is show...
Infinitesimal Carleson property for weighted measures induced by analytic self-maps of the unit disk
Calderón-Zygmund decomposition Carleson measure weighted Bergman space
2012/6/21
We prove that, for every $\alpha > -1$, the pull-back measure $\phi ({\cal A}_\alpha)$ of the measure $d{\cal A}_\alpha (z) = (\alpha + 1) (1 - |z|^2)^\alpha \, d{\cal A} (z)$, where ${\cal A}$ is the...
A note on Griffiths infinitesimal invariant for curves
Griffiths infinitesimal invariant curves Algebraic Geometry
2011/9/22
Abstract: Given a generic curve of genus $g\geqslant4$ and a smooth point $L\in W_{g-1}^{1}(C)$, whose linear system is base-point free, we consider the Abel-Jacobi normal function associated to $L^{\...
Prolongation on regular infinitesimal flag manifolds
Overdetermined systems prolongation filtered manifolds weighted jet bundles
2011/1/19
Regular infinitesimal flag structures are geometric structures, which occur as underlying structures of parabolic geometries. Among these structures we have for instance conformal structures, contact ...
We define Lie subalgebras of the group algebra of a finite pseudo-reflection group that are involved in the definition of the Cherednik KZsystems,and determine their structure.
Essential parabolic structures and their infinitesimal automorphisms
Essential parabolic structures infinitesimal automorphisms
2010/11/8
Using the theory of Weyl structures, we give a natural generalization of the notion of essential conformal structures and conformal Killing fields to arbitrary parabolic geometries. We show that a pa...
Infinitesimal Liouville currents, cross-ratios and intersection numbers
Infinitesimal Liouville currents cross-ratios intersection numbers
2010/12/8
Many classical objects on a surface S can be interpreted as cross-ratio functions on the circle at infinity of the universal covering eS.This includes closed curves considered up to homotopy, metrics ...
We define higher order infinitesimal noncommutative probability space and infinitesimal non-crossing cumulant functionals. In this framework,we generalize to higher order the notion of infinitesimal f...
On maximal primitive quotients of infinitesimal Cherednik algebras of gl_n

2010/11/26
We prove analogues of some of Kostant’s theorems for in-finitesimal Cherednik algebras of gln. As a consequence, it follows that in positive characteristic the Azumaya and smooth loci of the center of...
Adsorptive Separation of Infinitesimal Sulfur Oxide in Naphtha —Reactivation of Silica Gel Using Toluene and Dimethyl Ether—
Oxidative desulfurization Adsorption Naphtha Dimethyl ether
2009/8/4
Adsorption of sulfur oxide is one of the key techniques for producing extra-low-sulfur content naphtha during oxidative desulfurization. Reactivation and repeated use of adsorbent are quite important...

Oxidative desulfurization Adsorption Separation Naphtha Silica gel
2009/7/27
A model naphtha and benzothiophene-1,1-oxide (BTDO) were used to evaluate five commercial adsorbents in order to select a high-performance adsorbent for the separation of sulfur oxides generated in o...

2010/11/1
In this paper we study the fiber F of the rational Jones-Goodwillie character $$ F:=\hofiber(ch:K^\rat(A)@>>>HN^\rat(A)) $$ going from K-theory to negative cyclic homology of associative rings. We de...
