1Reliability
If separate machine learning models are used for each prediction task, then each task can be performed with specialized models, but computational resources and training time increase significantly
Solution Approach 1:
The patent implements a unified machine learning model that performs multiple prediction tasks (molecule generation, property prediction,, and structure prediction) simultaneously. This multi-functional model replaces the need for separate specialized models, reducing computational overhead while maintaining prediction accuracy through shared feature extraction and coordinated optimization across all tasks.
Solution Approach 2:
The patent combines multiple prediction tasks into a single integrated model architecture. By merging the molecule generation module, property prediction module, and structure prediction module into one unified system with shared parameters, the patent achieves better resource utilization and faster inference compared to using separate models for each task.
2Measurement precision
If multiple separate models are trained independently, then each model can be optimized for its specific task, but training time and computational resources increase
Solution Approach 1:
The patent trains multiple prediction tasks simultaneously within a unified model framework. By combining the molecule generation, property prediction, and structure prediction tasks into one model and training them together with shared parameters, the patent reduces total training time while maintaining task-specific optimization through differentiated loss functions and targeted gradient updates for each task.
Solution Approach 2:
The unified model is designed to handle multiple prediction tasks with a single training process. The model learns shared representations that benefit all tasks simultaneously, reducing the overall training time compared to independent training of separate models while still achieving task-specific precision through specialized output layers and loss functions for each task.
3Ease of operation
If separate models are stored and used independently, then each model can be deployed separately, but system complexity and memory usage increase
Solution Approach 1:
The patent integrates multiple prediction functionalities into a single model deployment. By combining molecule generation, property prediction, and structure prediction into one unified model, the patent reduces system complexity and memory usage while maintaining the ability to perform all tasks through a single deployment unit, eliminating the need to manage and coordinate multiple separate models.
