Available in PDF, EPUB and Kindle. Book excerpt: The intelligent use of electronic health record data opens up new opportunities to improve clinical care. Such data have the potential to uncover new sub-types of a disease, approximate the effect of a drug on a patient, and create tools to find patients with similar phenotypic profiles. Motivated by such questions, this thesis develops new algorithms for unsupervised and semi-supervised learning of latent variable, deep generative models – Bayesian networks parameterized by neural networks. To model static, high-dimensional data, we derive a new algorithm for inference in deep generative models. The algorithm, a hybrid between stochastic variational inference and amortized variational inference, improves the generalization of deep generative models on data with long-tailed distributions. We develop gradient-based approaches to interpret the parameters of deep generative models, and fine-tune such models using supervision to tackle problems that arise in few-shot learning. To model longitudinal patient biomarkers as they vary due to treatment we propose Deep Markov Models (DMMs). We design structured inference networks for variational learning in DMMs; the inference network parameterizes a variational approximation which mimics the factorization of the true posterior distribution. We leverage insights in pharmacology to design neural architectures which improve the generalization of DMMs on clinical problems in the low-data regime. We show how to capture structure in longitudinal data using deep generative models in order to reduce the sample complexity of nonlinear classifiers thus giving us a powerful tool to build risk stratification models from complex data.

Download or read book Missing Data Imputation in a Clinical Registry with Deep Generative Models written by Wangzhi Dai (S.M.) and published by . This book was released on 2021 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Missing data is a common problem in all data driven algorithms. An incomplete dataset can bring bias to the trained model, or cause failures in the deployment of models that require a complete input. A clinical registry is a record of patients information about their health history, status and the healthcare they receive during various periods of time. Due to the challenge of data collection and the un-structured nature of patients information, missing data is ubiquitous and can lead to series problems. Traditional imputing techniques to cope with missing data include simple mean or zero imputation and multivariate imputation that needs a more complex modeling. With the explosion of data and the advancement in the machine learning techniques, more advanced deep generative models have shown the ability to learn complex distributions in high dimensional space. In this work, we explored two deep generative models, Restricted Boltzmann Machine (RBM) and Variational Autoencoder (VAE) as potential modeling and imputation techniques for missing data. We examined the training of the model with incomplete dataset and mixed types of variable. For VAE, we further discussed a robust and efficient Markov Chain Monte Carlo (MCMC) sampling technique to estimate probability density of a given point. Two different Markov Chains, the random walk Metropolis and Hamiltonian Markov Chain were compared by their convergence speed. For imputation, we conducted synthetic experiments with Gaussian mixture model. We also applied the proposed methods to a real word clinical dataset, the Global Registry of Acute Coronary Events (GRACE) and compared the imputation performance to traditional methods like multivariate normal distribution.
Download or read book Deep Generative Modeling written by Jakub M. Tomczak and published by Springer Nature. This book was released on 2022-02-18 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook tackles the problem of formulating AI systems by combining probabilistic modeling and deep learning. Moreover, it goes beyond typical predictive modeling and brings together supervised learning and unsupervised learning. The resulting paradigm, called deep generative modeling, utilizes the generative perspective on perceiving the surrounding world. It assumes that each phenomenon is driven by an underlying generative process that defines a joint distribution over random variables and their stochastic interactions, i.e., how events occur and in what order. The adjective "deep" comes from the fact that the distribution is parameterized using deep neural networks. There are two distinct traits of deep generative modeling. First, the application of deep neural networks allows rich and flexible parameterization of distributions. Second, the principled manner of modeling stochastic dependencies using probability theory ensures rigorous formulation and prevents potential flaws in reasoning. Moreover, probability theory provides a unified framework where the likelihood function plays a crucial role in quantifying uncertainty and defining objective functions. Deep Generative Modeling is designed to appeal to curious students, engineers, and researchers with a modest mathematical background in undergraduate calculus, linear algebra, probability theory, and the basics in machine learning, deep learning, and programming in Python and PyTorch (or other deep learning libraries). It will appeal to students and researchers from a variety of backgrounds, including computer science, engineering, data science, physics, and bioinformatics, who wish to become familiar with deep generative modeling. To engage the reader, the book introduces fundamental concepts with specific examples and code snippets. The full code accompanying the book is available on github. The ultimate aim of the book is to outline the most important techniques in deep generative modeling and, eventually, enable readers to formulate new models and implement them.

Book excerpt: Recent advances in generative modeling, based on large scale deep neural networks, provide a novel approach for sharing individual-level datasets (micro-data) without privacy concerns. Unlike differential privacy, which enforces a specific query mechanism on data to ensure privacy, generative models can accurately learn the statistical patterns of such micro-data and then be used to generate ,Äúsynthetic data,Äù that accurately reflects these statistical patterns, yet contain none of the original data itself, and thus can be safely shared for analysis and modeling without compromising privacy. The successful application of these techniques to various industries including healthcare, finance, and autonomous vehicles is promising and results in continued investment in research and development of generative models in both academia and industry.

Download or read book Deep Generative Models for Medical Images and Beyond written by Yuan Xue and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep generative models such as generative adversarial networks (GANs) or variational autoencoders (VAEs) have been extensively studied in unsupervised image generation tasks where given training data, the goal is to try and generate new samples from the same distribution. Despite such research efforts, components of such generative models, especially GANs, have rarely been integrated into supervised learning scenarios such as in classification, segmentation, and regression tasks in the literature. To improve the generality and applicability of deep generative models, in this dissertation, we show the potential of integrating components of generative models into a variety of supervised learning tasks for improved performance. We propose several advanced deep learning based generative methods that are complementary to traditional supervised learning methods, for different medical image analysis applications as well as architecture design applications which achieve state-of-the-art performances in our experiments. First, we present an image segmentation method that consists of a segmentor (i.e., generator) network and a critic (i.e., discriminator) network, which is trained in an adversarial learning fashion, so that feedback from the critic network can help the segmentor generate accurate and realistic segmentations. We also discuss other segmentation tasks, including 3D organ segmentation and infant video segmentation. Then, we present a multimodal recurrent model with attention for the automatic generation of medical reports given X-Rays images. We also propose several deep generative model architectures with structural integrity for indoor wireframe scene rendering and automated floor plan generation. Finally, we propose a series of synthetic augmentation models that generate synthetic images and then selectively choose high-quality synthetic images to augment training sets and improve histopathology image classification results.
