This document provides an introduction to the rules and structure of American football in the National Football League (NFL). It outlines the basic field setup with offenses and defenses of 11 players each. It explains the concept of downs, where a team has 4 attempts to advance 10 yards, and what happens if they fail to convert or succeed. It also describes common forms of scoring like touchdowns, field goals, and safeties. The document provides some key rules around penalties, interceptions, fumbles, and sacks. It includes the schedule for the 2022-2023 NFL regular season and playoffs culminating in the Super Bowl each February.

Predicting drug-target interactions (DTI) is an essential part of the drug discovery process, which is an expensive process in terms of time and cost. Therefore, reducing DTI cost could lead to reduced healthcare costs for a patient. In addition, a precisely learned molecule representation in a DTI model could contribute to developing personalized medicine, which will help many patient cohorts. In this paper, we propose a new molecule representation based on the self-attention mechanism, and a new DTI model using our molecule representation. The experiments show that our DTI model outperforms the state of the art by up to 4.9% points in terms of area under the precision-recall curve. Moreover, a study using the DrugBank database proves that our model effectively lists all known drugs targeting a specific cancer biomarker in the top-30 candidate list.

This document outlines several unsupervised methods for integrating multi-omic data, including matrix factorization methods (iCluster+), Bayesian methods (BCC), network-based methods (SNF), and multiple kernel learning (rMKL-LPP). It provides details on the procedures and assumptions of each method and discusses applications to discovering subtypes in cancers like breast cancer and glioblastoma multiforme.

LassoLiangqun Lu

��

This document discusses Lasso and Bayesian Lasso regression. It provides an overview of Lasso, which performs variable selection by shrinking coefficients towards zero. Bayesian Lasso regression places Laplace priors on the coefficients, allowing posterior inference using Gibbs sampling. The document demonstrates an example of Bayesian Lasso for diabetes data and prostate cancer data, comparing errors to non-Bayesian Lasso and examining coefficient estimates.

This document discusses using generative adversarial networks (GANs) for information retrieval (IRGAN). It presents GANs and describes how IRGAN formulates a minimax game that unifies generative and discriminative IR models. Experiments on web search, item recommendation, and question answering using real datasets show IRGAN achieves significant performance gains over other ranking models. The generative model benefits more in pointwise IRGAN, while the discriminative model benefits more in pairwise IRGAN.

Deep Learning Application in BiologyLiangqun Lu

Group meeting to discuss two papers on deep learning applications in healthcare. The first paper examines using a deep neural network to classify skin cancer at a dermatologist level using images. The second reviews opportunities and challenges for using deep learning in healthcare. Deep learning uses neural network models with many layers to extract higher-level features from data. It has achieved breakthroughs in areas like computer vision, speech recognition, and natural language processing. Transfer learning allows applying models trained on large datasets to new related problems.

- 13 putative driver genes were identified from TCGA somatic mutation data including TP53, CTNNB1, and AXIN1. Some genes were associated with clinical characteristics and survival outcomes. - Multi-omic data from TCGA including RNA-seq, miRNA-seq, DNA methylation, and copy number variation were integrated using similarity network fusion and clustering. This identified 5 subtypes of HCC with different survival profiles. - Predictive models were built for each subtype on individual omics datasets, showing concordance between 56-87%. Analysis of gene expression profiles revealed different active biological processes between the subtypes.

The document discusses hepatocellular carcinoma (HCC) epidemiology and etiology. It states that HCC is the most common type of liver cancer and the second leading cause of cancer death worldwide. The risk of HCC is highest in East Asia and Africa. Major risk factors include hepatitis B and C infections, cirrhosis, alcohol abuse, and aflatoxin exposure. HCC develops through a multi-step process as a result of chronic liver injury and inflammation leading to cirrhosis, then the accumulation of genetic and genomic alterations in hepatocytes results in malignant transformation and tumor progression. Key molecular alterations involved in hepatocarcinogenesis include telomere shortening, p53 mutations, and genomic instability.

This document discusses post-traumatic stress disorder (PTSD) and efforts to identify biomarkers for PTSD. It provides background information on PTSD prevalence, diagnosis, and current treatment options. The document then describes a study to identify genetic and molecular biomarkers for PTSD by analyzing differences in genes, miRNAs, and metabolites between healthy control samples and PTSD patient samples using machine learning techniques. The study aims to identify candidate biomarkers that could help diagnose and monitor PTSD.

This document outlines a study that used machine learning methods to predict post-traumatic stress disorder (PTSD) based on clinical characteristics from patient data. The study used datasets containing information from 957 patients exposed to traumatic events and assessed for PTSD at three time points. Several machine learning algorithms were tested and achieved AUC scores from 0.76 to 0.82 in predicting PTSD. Feature selection found that focusing on the top consistent predictive features improved accuracy. The study demonstrated the feasibility of machine learning for PTSD prediction and suggests incorporating additional data like genomics could further improve results.

This document discusses using gene expression profiling to classify breast cancers, predict patient survival, and determine appropriate treatment. It describes developing a gene signature from a training set of 115 breast cancer samples and validating it on an independent test set of 171 samples. The signature was able to predict survival and response to chemotherapy versus endocrine therapy in estrogen receptor-positive breast cancer patients.

This document summarizes a study that used machine learning methods to analyze gene expression data from mouse samples with and without PTSD-like symptoms. The study found that there were more differently expressed genes in the brain samples compared to other tissues. Logistic regression was able to accurately classify 92.2% of the samples as PTSD or control. While 94 genes were identified as potentially contributing to PTSD, further validation of the model is still needed due to noise in the grouped data.
