The variance of causal effect estimators for binary v-structures

open access: yesJournal of Causal Inference, 2022
Adjusting for covariates is a well-established method to estimate the total causal effect of an exposure variable on an outcome of interest. Depending on the causal structure of the mechanism under study, there may be different adjustment sets, equally ...

An Improved Particle Swarm Optimization Algorithm for Bayesian Network Structure Learning via Local Information Constraint

open access: yesIEEE Access, 2021
At present, in the application of Bayesian network (BN) structure learning algorithm for structure learning, the network scale increases with the increase of number of nodes, resulting in a large scale of structure search space, which is difficult to ...

A Novel BN Learning Algorithm Based on Block Learning Strategy

open access: yesSensors, 2020
Learning accurate Bayesian Network (BN) structures of high-dimensional and sparse data is difficult because of high computation complexity. To learn the accurate structure for high-dimensional and sparse data faster, this paper adopts a divide and ...

Hard and Soft EM in Bayesian Network Learning from Incomplete Data

open access: yesAlgorithms, 2020
Incomplete data are a common feature in many domains, from clinical trials to industrial applications. Bayesian networks (BNs) are often used in these domains because of their graphical and causal interpretations.

Temporal context and latent state inference in the hippocampal splitter signal

open access: yeseLife, 2023
The hippocampus is thought to enable the encoding and retrieval of ongoing experience, the organization of that experience into structured representations like contexts, maps, and schemas, and the use of these structures to plan for the future. A central

Multiscale Causal Structure Learning

open access: yes, 2022
The inference of causal structures from observed data plays a key role in unveiling the underlying dynamics of the system. This paper exposes a novel method, named Multiscale-Causal Structure Learning (MS-CASTLE), to estimate the structure of linear causal relationships occurring at different time scales. Differently from existing approaches, MS-CASTLE

Synthesis of a novel photoactivatable glucosylceramide cross-linker

open access: yesJournal of Lipid Research, 2016
The biosynthesis of glucosylceramide (GlcCer) is a key rate-limiting step in complex glycosphingolipid (GSL) biosynthesis. To further define interacting partners of GlcCer, we have made a cleavable, biotinylated, photoreactive GlcCer analog in which the ...

Variable Chromosome Genetic Algorithm for Structure Learning in Neural Networks to Imitate Human Brain

open access: yesApplied Sciences, 2019
This paper proposes the variable chromosome genetic algorithm (VCGA) for structure learning in neural networks. Currently, the structural parameters of neural networks, i.e., number of neurons, coupling relations, number of layers, etc., have mostly been
