Book excerpt: Scientific Study from the year 2023 in the subject Computer Science - Bioinformatics, grade: 10, VIT University (VIT), course: Computer Science, language: English, abstract: The use of machine learning for stroke prediction represents a powerful tool in enhancing patient care and reducing stroke-related mortality and disability. By focusing on key risk factors and leveraging extensive healthcare data, machine learning can substantially improve the accuracy and effectiveness of stroke prediction. This project aims to harness the potential of machine learning to better identify individuals at high risk of suffering a stroke and provide them with early, targeted interventions, ultimately saving lives and improving patient outcomes. The importance of predicting strokes cannot be overstated. Strokes are a leading cause of mortality and disability worldwide. Early detection and prevention can have a substantial impact on patient outcomes. Leveraging machine learning algorithms for stroke prediction can significantly improve the accuracy and efficacy of identifying high-risk patients. The primary objective of this project is to develop a precise stroke prediction system that can recognize high-risk patients based on a wide range of risk factors, including age, gender, medical history, lifestyle choices, and genetic factors. By creating a reliable model for stroke prediction, healthcare professionals can administer early interventions, potentially reducing stroke incidence and improving patient outcomes. The project's scope includes analyzing electronic health record (EHR) data to identify the key elements essential for stroke prediction. EHRs contain valuable information, including patient demographics, medical history, clinical findings, and other factors relevant to constructing a stroke prediction model. Machine learning for stroke prediction involves several stages. Initially, a dataset of relevant variables potentially influencing stroke occurrence is identified. This dataset may encompass demographic details, clinical information, laboratory tests, medical images, genetic data, and lifestyle factors. Subsequently, the dataset is cleaned and preprocessed to remove noise and inconsistencies. A machine learning algorithm is chosen, and the data is divided into training and testing groups. The algorithm is trained using the training data to identify patterns and relationships between variables and stroke occurrence. Once the model is trained, it is evaluated using the testing data to assess its performance.

This book was released on 2023-07-15 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this project, we will perform an analysis and prediction task on stroke data using machine learning and deep learning techniques. The entire process will be implemented with Python GUI for a user-friendly experience. We start by exploring the stroke dataset, which contains information about various factors related to individuals and their likelihood of experiencing a stroke. We load the dataset and examine its structure, features, and statistical summary. Next, we preprocess the data to ensure its suitability for training machine learning models. This involves handling missing values, encoding categorical variables, and scaling numerical features. We utilize techniques such as data imputation and label encoding. To gain insights from the data, we visualize its distribution and relationships between variables. We create plots such as histograms, scatter plots, and correlation matrices to understand the patterns and correlations in the data. To improve model performance and reduce dimensionality, we select the most relevant features for prediction. We employ techniques such as correlation analysis, feature importance ranking, and domain knowledge to identify the key predictors of stroke. Before training our models, we split the dataset into training and testing subsets. The training set will be used to train the models, while the testing set will evaluate their performance on unseen data. We construct several machine learning models to predict stroke. These models include Support Vector, Logistic Regression, K-Nearest Neighbors (KNN), Decision Tree, Random Forest, Gradient Boosting, Light Gradient Boosting, Naive Bayes, Adaboost, and XGBoost. Each model is built and trained using the training dataset. We train each model on the training dataset and evaluate its performance using appropriate metrics such as accuracy, precision, recall, and F1-score. This helps us assess how well the models can predict stroke based on the given features. To optimize the models' performance, we perform hyperparameter tuning using techniques like grid search or randomized search. This involves systematically exploring different combinations of hyperparameters to find the best configuration for each model. After training and tuning the models, we save them to disk using joblib. This allows us to reuse the trained models for future predictions without having to train them again. With the models trained and saved, we move on to implementing the Python GUI. We utilize PyQt libraries to create an interactive graphical user interface that provides a seamless user experience. The GUI consists of various components such as buttons, checkboxes, input fields, and plots. These components allow users to interact with the application, select prediction models, and visualize the results. In addition to the machine learning models, we also implement an ANN using TensorFlow. The ANN is trained on the preprocessed dataset, and its architecture consists of a dense layer with a sigmoid activation function. We train the ANN on the training dataset, monitoring its performance using metrics like loss and accuracy. We visualize the training progress by plotting the loss and accuracy curves over epochs. Once the ANN is trained, we save the model to disk using the h5 format. This allows us to load the trained ANN for future predictions. In the GUI, users have the option to choose the ANN as the prediction model. When selected, the ANN model is loaded from disk, and predictions are made on the testing dataset. The predicted labels are compared with the true labels for evaluation. To assess the accuracy of the ANN predictions, we calculate various evaluation metrics such as accuracy score, precision, recall, and classification report. These metrics provide insights into the ANN's performance in predicting stroke. We create plots to visualize the results of the ANN predictions. These plots include a comparison of the true values and predicted values, as well as a confusion matrix to analyze the classification accuracy. The training history of the ANN, including the loss and accuracy curves over epochs, is plotted and displayed in the GUI. This allows users to understand how the model's performance improved during training. In summary, this project covers the analysis and prediction of stroke using machine learning and deep learning models. It encompasses data exploration, preprocessing, model training, hyperparameter tuning, GUI implementation, ANN training, and prediction visualization. The Python GUI enhances the user experience by providing an interactive and intuitive platform for exploring and predicting stroke based on various features.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: We developed machine learning models to predict the occurrence of post-stroke delirium using the clinical and brain-regional characteristics of acute ischemic stroke patients.Method: We screened for delirium using the Confusion Assessment Method and used Diagnostic and Statistical Manual of Mental Disorders (5th edition) to diagnose delirium for the 675 consecutive acute ischemic stroke patients, who were admitted in stroke unit from August 2017 to July 2018. The clinical and brain imaging data of the patients were used to to test machine learning algorithms for the prediction of post-stroke delirium. We compared accuracy of machine learning algorithms including Support Vector Machine (SVM), Random Forest (RF) and Tree-based Gradient Boosting (XGBoost) performed with clinical and brain imaging. Results: Post-stroke delirium occurred in 66 (9.8%) of the total patients. On the comparison of the prediction accuracy of delirium occurrence, RF (93%) and XGBoost (92%) showed similar rates, and SVM (81%) was lower than two others. Top linked-variables to be included for the prediction of post-stroke delirium were age (feature importance, 1.50), National Institute of Health Stroke Scale (1.07) and modified Rankin Scale (0.73) at admission, side of old (0.69) and new stroke (0.47), size of new lesion (0.37), male (0.36), old infarction on cognition-related region (0.33). Conclusion: The present study shows the accuracy of the machine learning models to predict post-stroke delirium using the clinical and brain-regional characteristics of acute ischemic stroke patients. The top ranked variables could provide the possibilities to improve the prediction rate of post-stroke delirium.

Download or read book Interpretable Machine Learning Methods for Stroke Prediction written by Rebecca Zhang (S.M.) and published by . This book was released on 2019 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Machine learning has long been touted as the next big tool, revolutionizing scientific endeavors as well as impacting industries like retail and finance. Naturally, there is much interest in the potential of next improving healthcare. However, using traditional machine learning approaches in this domain has many difficulties, chief among which is the issue of interpretability. We focus on the medical condition of stroke, a particularly desirable problem to target because it is one of the most prevalent and yet preventable conditions affecting Americans today. In this thesis, we apply novel interpretable prediction techniques to the problem of predicting stroke presence, location, acuity, and mortality risk for patient populations at two different hospital systems. We show that using an interpretable, optimal tree-based approach is roughly as effective if not better than black-box approaches. Using the clinical learnings from these studies, we explore new interpretable methodologies designed with medical applications and their unique challenges in mind. We present a novel regression algorithm to predict outcomes when the population is comprised of notably different subpopulations, and demonstrate that this gives comparable performance with improved interpretability. Finally, we explore new natural language processing techniques for machine learning from text. We propose an alternate end-to- end framework for going from unprocessed textual data to predictions, with an interpretable linguistics-based approach to model words. Altogether, this work demonstrates the promise that new parsimonious, interpretable algorithms have in the domain of stroke and broader healthcare problems.
