Counting and Exploring Sizes of Markov Equivalence Classes of Directed Acyclic Graphs
Directed acyclic graphs Markov equivalence class Size distribution Causal- ity
2016/1/26
When learning a directed acyclic graph (DAG) model via observational data, one gener-ally cannot identify the underlying DAG, but can potentially obtain a Markov equivalence class. The size (the numbe...

Structure-Preserving Signatures on Equivalence Classes and their Application to Anonymous Credentials
Public key cryptography structure-preserving signatures attribute-based anonymous credentials
2016/1/7
Structure-preserving signatures are a quite recent but important building block for many
cryptographic protocols. In this paper, we introduce a new type of structure-preserving signatures, which
all...
EUF-CMA-Secure Structure-Preserving Signatures on Equivalence Classes
public-key cryptography structure-preserving signatures
2016/1/5
At ASIACRYPT’14 Hanser and Slamanig proposed a new primitive called structure-preserving signatures
on equivalence classes (SPS-EQ) and used it to construct very efficient attribute-based anonymous

Equivalence Classes of Full-Dimensional 0/1-Polytopes with Many Vertices
n-cube full-dimensional 0/1-polytope symmetry hyperplane Polya theory
2014/6/3
Let Qn denote the n-dimensional hypercube with the vertex set Vn = {0, 1}n. A 0/1-polytope of Qn is a convex hull of a subset of Vn. This paper is concerned with the enumeration of equivalence classes...
Jointly interventional and observational data: estimation of interventional Markov equivalence classes of directed acyclic graphs
Causal inference Interventions BIC Graphical model Maximum likelihood estimation Greedy equivalence search
2013/4/27
In many applications we have both observational and (randomized) interventional data. We propose a Gaussian likelihood framework for joint modeling of such different data-types, based on global parame...

Non-identifiability, equivalence classes, and attribute-specific classification in Q-matrix based Cognitive Diagnosis Models
CDM diagnostic classification DINA DINO NIAD-DINA Q-matrix consistency identifiability
2013/4/27
There has been growing interest in recent years in Q-matrix based cognitive diagnosis models. Parameter estimation and respondent classification under these models may suffer due to identifiability is...

Towards Characterizing Markov Equivalence Classes for Directed Acyclic Graphs with Latent Variables
DAG maximal ancestral graph Markov equivalence
2012/9/18
It is well known that there may be many causal explanations that are consistent with a given set of data. Recent work has been done to represent the common aspects of these explanations into one repre...
