This document summarizes a study that analyzed genomic runs of homozygosity (ROH) in populations from the HGDP dataset to understand population history and consanguinity. The study found that Native American populations had the longest ROHs, Oceanian populations had the most short ROHs, and South/Central Asian and West Asian populations had more long ROHs, reflecting consanguineous marriages. Hunter-gatherer populations generally had more total ROH lengths than farmer populations. Overall, short ROHs made up most ROHs present across populations, but the most inbred populations had more long ROHs, providing information about demographic history and disease risk.

1. The document describes a method using unsupervised deep learning for breast density segmentation and mammographic risk scoring from medical images.
2. A convolutional sparse autoencoder (CSAE) model is used to learn features from unlabeled mammogram patch data at multiple scales to perform the segmentation and risk scoring tasks.
3. Experimental results show the CSAE approach achieves state-of-the-art performance for both density segmentation and texture-based cancer risk prediction.
The document discusses Wright's F-statistics and Cockerham's θ-statistics, which are methods used to calculate genetic differentiation between populations. It also discusses methods to detect signatures of positive selection, including Extended Haplotype Homozygosity (EHH), integrated Haplotype Score (iHS), and cross population Extended Haplotype Homozygosity (xpEHH). EHH detects when a particular haplotype is over-represented in a population by measuring how quickly homozygosity declines with genetic distance from the core haplotype. iHS and xpEHH are derived from EHH scores to identify haplotypes that have increased in frequency due to positive selection.
New Epidemiologic Measures in Multilevel Study: Median Risk Ratio, Median Haz...Jinseob Kim
This document introduces new epidemiological measures for multilevel studies, including the median risk ratio, median hazard ratio, and median beta. It begins with an introduction and overview of intraclass correlation coefficients and variance partition coefficients. It then provides formulas for calculating the new measures based on binomial, Poisson, and Cox proportional hazards multilevel models. Examples are shown using real data on breast cancer and families to demonstrate how to compute and interpret the median odds ratio, median risk ratio, and median hazard ratio. The document concludes by discussing applications of the new measures to other data types like count and survival data.
This document provides code to calculate extended haplotype homozygosity (EHH), integrated haplotype score (iHS), and cross-population composite likelihood ratio (XP-CLR) from population genetics data. It loads example data, calculates EHH and iHS for a set of SNPs on chromosome 12, and plots the results. It then loads example results for composite likelihood ratio (CLR) between cattle populations and calculates relative extended haplotype homozygosity (REHH) between the populations, plotting the output. Finally, it calculates iHS for all SNPs on chromosome 1 from one of the cattle populations and plots those results.

EHH detects when a haplotype is over-represented in a population due to recent positive selection. iHS and xp-EHH are derived from EHH to identify specific genomic regions under selection. The document uses examples and figures to illustrate key concepts.
The document introduces DISMOD and DISMOD II, software used to model disease burden. DISMOD uses differential equations to estimate disease measures like incidence, remission, and case fatality from available data. DISMOD II improves on DISMOD by allowing estimation of measures from other available data using statistical methods. It also introduces a graphical user interface. Both tools are used to model disease measures over age, sex, and location where data may be limited or uncertain. Newer approaches aim to have more flexible models that account for covariates and better represent uncertainty.
This document discusses analyzing time-series data using a case-crossover study design and conditional logistic regression. It begins with concepts of individual versus population risk, the case-crossover design which uses a subject's other time periods as controls, and how the data structure changes. It then reviews basic linear regression, logistic regression, and conditional logistic regression. Finally, it discusses practical issues and demonstrates using the season package in R to conduct case-crossover analyses and conditional logistic regression.
This document discusses analyzing time-series data using generalized additive models (GAM). It covers non-linear issues in regression, GAM theory including various spline methods and model selection, descriptive analysis of time-series data through plots, and applying GAM to analyze incidence data from Seoul using the mgcv package in R. Examples are provided to illustrate spline fitting and model selection for both Poisson and quasipoisson GAMs.

1. This document discusses the history and development of deep learning from the perceptron in 1958 to modern deep neural networks.
2. It describes the key milestones as the perceptron in 1958, multilayer perceptrons in the 1980s which could solve the XOR problem, and Boltzmann machines in the 1980s which introduced unsupervised learning.
3. Deep learning has gained popularity since 2010 due to increases in data and computational power. It is now being applied to problems in computer vision, natural language processing and other domains.
This document discusses the changing role of human scientists in an era where metahuman science has advanced far beyond human comprehension. It outlines how human scientists have shifted from conducting original research to interpreting and analyzing the work of metahumans through hermeneutic approaches like textual analysis of publications, reverse engineering of technological artifacts, and remote sensing of research facilities. While some see these as a waste of time, the document argues they are worthwhile pursuits that continue scientific inquiry and increase human knowledge, and may even uncover applications not considered by metahumans.
This document discusses advanced tree-based machine learning methods including bagging, random forests, and boosting. Bagging involves resampling data and growing trees on each sample to average predictions and reduce variance compared to a single tree. Random forests build on bagging by randomly selecting features at each split. Boosting fits trees sequentially to emphasize training examples that previous trees misclassified to produce a stronger learner. These ensemble methods aggregate multiple tree models to improve over a single decision tree.
This document discusses the history and development of deep learning. It describes how early neural networks like perceptrons had limitations in tasks like the XOR problem. The development of multilayer perceptrons with hidden layers and the backpropagation algorithm helped address these issues. However, training these networks remained a challenge until recent breakthroughs in unsupervised learning using methods like restricted Boltzmann machines and deep belief networks. These approaches pre-train the lower layers of neural networks in an unsupervised manner before fine-tuning the entire network with a supervised method like backpropagation.
