Machine Learning Cardiovascular Risk Prediction Across Complex Health Factors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional statistical models fail to accurately predict cardiovascular disease risk due to the complex interplay of various factors, including hypertension, obesity, genetic predisposition, and environmental influences, necessitating a comprehensive data analysis approach.
Innovation Solution
A machine learning model is employed to analyze health data, including demographic, personal habits, treatment, blood pressure, and environmental indicators, using a dataset from Taiwan Consortium of Hypertension-associated Cardiac Disease and Taiwan Health and Welfare Data Science Center, trained with logistic regression, deep neural networks, and gradient boosting algorithms, to predict cardiovascular disease risk over varying time periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional statistical models are used to predict cardiovascular disease risk, then the model development process is simple, but the prediction accuracy is insufficient due to inability to capture complex causal relationships
Solution Approach 1:
The patent replaces conventional statistical models with machine learning models that use AI algorithms to analyze health data. This substitution enables the system to capture complex non-linear relationships and interactions between multiple risk factors (hypertension, obesity, genetic predisposition, environmental factors) that conventional statistical models cannot adequately represent, thereby significantly improving prediction accuracy while managing model complexity through automated learning processes
2Measurement precision
If comprehensive data analysis is performed to capture all risk factors, then the prediction accuracy improves, but the data processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary data processing steps including data cleaning, transformation, and feature engineering before the actual prediction modeling. Historical health data is pre-processed to handle missing values, normalize formats, and extract meaningful features from raw data. This preliminary action reduces the computational burden during the actual prediction phase, allowing comprehensive analysis of multiple risk factors without excessive processing time delays
3Adaptability or versatility
If multiple risk factors and their interactions are analyzed, then the comprehensiveness of the model improves, but the difficulty of detecting and measuring all relevant factors increases
Solution Approach 1:
The patent introduces an intermediary data processing layer that includes feature extraction and transformation modules. These intermediaries convert raw, difficult-to-measure risk factors (such as genetic predisposition, environmental influences, and complex lifestyle factors) into standardized, measurable features that the machine learning model can process. The intermediary layer simplifies the detection and measurement of multifaceted risk factors while maintaining comprehensive model coverage
Data Source
AI summary
Methods and computer-implemented methods are used to predict a risk of cardiovascular disease by using a machine learning mode to analyze a relationship between the occurrence of cardiovascular disease and health data of patients, in which the health data contain demographic data, personal habits data, disease data, treatment data, blood analysis data, blood pressure data and environmental data.
