Congrats to Sean for submitting the final paper from his PhD thesis to bioRxiv!
eQTL networks review
Congrats to Sean for the publication of his review article “eQTLs as causal instruments for the reconstruction of hormone linked gene networks”! The review is part of a special issue “Insights in Systems Endocrinology: 2021” in Frontiers in Endocrinology.
Preprint by Ammar
Ammar has posted a preprint of his paper “rfPhen2Gen: A machine learning based association study of brain imaging phenotypes to genotypes” on arXiv. In this paper, Ammar evaluated random forest regression as a method to identify biologically relevant associations by learning models to predict SNPs from imaging features, using data for 518,484 SNPs and 56 brain imaging traits from the ADNI study.
G3 paper
Our paper “Restricted maximum-likelihood method for learning latent variance components in gene expression data with known and unknown confounders” has been published in G3. In this paper we analyse the mathematical structure of a class of statistical models for learning hidden factors influencing gene expression data and show that a new algorithm based on the analytical results is orders of magnitude faster than the standard algorithms for solving this class of models.
Congrats Ammar!
Congratulations to Ammar, whose paper “High-dimensional multi-trait GWAS by reverse prediction of genotypes” has been accepted for presentation at CIBB 2021!
Congrats Ramin!
Congratulations to Ramin, whose paper “A graph feature auto-encoder for the prediction of unobserved node features on biological networks” has been published in BMC Bioinformatics!
Two preprints by Ramin
Congrats to Ramin for posting no less than two preprints on arXiv:
- Tesla-Rapture: A Lightweight Gesture Recognition System from mmWave Radar Point Clouds
- Integrating Sensing and Communication in Cellular Networks via NR Sidelink
Both papers result from a collaboration between Ramin and Dariush Salami at the Ambient Intelligence group at Aalto University, and introduce new graph neural network-based methods for analyzing point cloud data.
Great to see when students independently initiate projects and push them through to completion (exposing the limits of their supervisor’s knowledge in the process 🙂
Molecular Omics cover article
Congratulations to Adriaan for having his article (and art work!) selected for the cover of the April issue of Molecular Omics!
Causal network inference preprint
Adriaan’s paper “Comparison between instrumental variable and mediation-based methods for reconstructing causal gene networks in yeast” has been posted on biorXiv. In this paper we used Findr to compare several methods for causal inference from genomics and transcriptomics data, using a recently published dataset of 1,012 segregants from a cross between two budding yeast strains.
Frontiers Genetics paper
Lingfei’s paper, “High-dimensional Bayesian network inference from systems genetics data using genetic node ordering” has been published in Frontiers in Genetics, in a Special Topic on Machine Learning and Network-Driven Integrative Genomics.
In this paper, we present a highly efficient approach for reconstructing Bayesian gene regulatory networks when prior information for the inclusion of edges exists or can be inferred from the available data. The method is implemented in the Findr software.
