PMD4: PERFORMANCE OF TWO CONDITIONAL EXPECTATION METHODS UNDER UNOBSERVED SELECTION BIAS

CONDITIONAL EXPECTATION IN THE KOPKA'S D-POSETS

The notion of a $D$-poset was introduced in a connection withquantum mechanical models. In this paper, we introduce theconditional expectation of  random variables on theK^{o}pka's $D$-Poset and prove the basic properties ofconditional expectation on this  structure.

A Conditional Expectation Approach to Model Selection and Active Learning under Covariate Shift

In the previous chapter, Kanamori and Shimodaira provided generalization error estimators which can be used for model selection and active learning. The accuracy of these estimators is theoretically guaranteed in terms of the expectation over realizations of training input-output samples. In practice, we are only given a single realization of training samples. Therefore, ideally, we want to hav...

Conditional Expectation

Let μ and λ be two positive bounded measures on the same meaurable space (Ω,F). We call μ and λ equivalent, and write μ ≡ λ, if they have the same null sets— so, if they were probability measures, the notion of “a.s.” would be the same for both. More generally, we call λ absolutely continuous (AC) w.r.t. μ, and write λ μ, if μ(A) = 0 implies λ(A) = 0, i.e., if every μ-null set is also λ-null. W...

Evolution of conditional cooperation under multilevel selection

We study the emergence of conditional cooperation in the presence of both intra-group and inter-group selection. Individuals play public goods games within their groups using conditional strategies, which are represented as piecewise linear response functions. Accordingly, groups engage in conflicts with a certain probability. In contrast to previous studies, we consider continuous contribution...
