Machine Learning Model for Predicting Immunotherapy Adverse Symptoms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for predicting adverse symptoms during immunotherapy are limited by incomplete data sets, sparse patient records, and the inability to accurately inform patients and physicians about potential symptoms, leading to anxiety and unnecessary medical visits.
Innovation Solution
A machine learning model using a light gradient-boosting framework is trained with genuine and synthetic data to predict adverse symptoms in immunotherapy, incorporating medical history and therapy features, and dynamically updates training data for improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional prediction methods are used with incomplete data sets, then the system is simpler to implement, but the prediction accuracy is insufficient
Solution Approach 1:
The patent creates synthetic copies of patient data by generating artificial patient profiles that mimic real patient characteristics and outcomes. These synthetic data copies are used to train machine learning models when real data is insufficient, thereby improving prediction accuracy without requiring additional complex data collection infrastructure.
Solution Approach 2:
The system performs preliminary data preparation by pre-generating synthetic training data and pre-training machine learning models before actual prediction is needed. This preliminary action ensures that when predictions are required, the models are already prepared and can provide accurate results without requiring complex real-time data processing.
2Measurement precision
If more comprehensive patient data is collected, then the prediction accuracy improves, but the data privacy risks increase
Solution Approach 1:
Instead of collecting and storing sensitive real patient data, the system creates synthetic copies that preserve the statistical properties and patterns of real data while containing no actual personal information. This copying approach enables comprehensive data analysis for improved prediction accuracy while inherently protecting patient privacy since the synthetic data cannot be traced back to real individuals.
Solution Approach 2:
The synthetic data acts as an intermediary between the need for comprehensive patient information and privacy protection requirements. It mediates by providing all the necessary predictive features and patterns without exposing actual patient identities or sensitive personal health information, thus resolving the conflict between data comprehensiveness and privacy.
3Reliability
If dynamic data updating is implemented, then the prediction model remains accurate over time, but the computational resources required increase
Solution Approach 1:
The system implements periodic updates of the machine learning models with newly available data rather than continuous real-time updates. This periodic action maintains prediction reliability by ensuring models are refreshed at appropriate intervals while avoiding the excessive computational energy consumption that would result from constant continuous updating.
Solution Approach 2:
The system selectively discards outdated or redundant training data while retaining essential patterns and insights. By discarding unnecessary data and recovering only the most valuable information for model retraining, the system maintains prediction reliability over time while minimizing the computational energy required for data processing and model updates.

AI summary
A method for predicting an adverse symptom to immunotherapy. The method comprises receiving a medical history and one or more therapy features, related to a food allergy, of a patient; evaluating a probability of the patient experiencing, respectively, each of one or more symptoms during immunotherapy; communicating the probability for each of the one or more symptoms to the patient and/or a physician of the patient.
