Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current methods rely on chemical structure similarity and known DTI data to predict drug efficacy, then prediction can be performed, but the process is error-prone and non-scalable
Solution Approach 1:
The patent replaces manual biochemical target understanding and chemical structure analysis with an automated machine learning system. The ML model processes DDI embedding values and chemical structure data elements to predict efficacy, eliminating the need for individual expert interpretation and enabling scalable automation.
Solution Approach 2:
The patent introduces DDI embedding values as an intermediary representation that captures drug interaction patterns. This embedding space serves as a mediator between raw DDI data and the machine learning model, enabling the system to leverage complex interaction patterns without requiring direct manual analysis of each interaction.
2Measurement precision
If individual understanding of biochemical targets is used to analyze predicted effects, then efficacy determination can be made, but the process becomes non-scalable and error-prone
Solution Approach 1:
The patent replaces manual biochemical analysis with automated machine learning inference. The trained ML model directly processes DDI embedding values and chemical structure data to output efficacy predictions, eliminating the need for individual expert interpretation and enabling high-throughput automated decision-making.
3Reliability
If DDI data is utilized to extract latent information, then prediction accuracy improves, but the system complexity increases
Solution Approach 1:
The patent extracts latent information from DDI data by computing DDI embedding values in a reduced-dimensional space. This embedding process captures essential interaction patterns while filtering out noise and redundancy, enabling the ML model to work with compressed representations that reduce computational complexity while maintaining predictive accuracy.
