Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional machine learning models are used to generate embeddings for neuronal cells, then the system can process images, but the accuracy is insufficient due to complex cell physiology and irregular plating patterns
Solution Approach 1:
The patent combines multiple embedding models into an ensemble system where each model processes phenomic images independently and their outputs are aggregated. This merging of multiple models addresses the insufficiency of single conventional models in accurately capturing complex neuronal cell characteristics and irregular plating patterns, thereby improving both measurement precision and prediction reliability.
Solution Approach 2:
The system creates a composite embedding approach by integrating results from multiple diverse embedding models. Similar to composite materials combining different substances for enhanced properties, this composite embedding strategy leverages the strengths of each individual model to achieve superior accuracy in representing neuronal cell phenotypes despite their complex physiology and irregular arrangements.
2Reliability
If multiple embedding models are combined to improve accuracy, then the prediction reliability improves, but the computational resources and system complexity increase
Solution Approach 1:
The system segments the overall embedding task into multiple independent model computations that can be executed in parallel. Each embedding model processes the input independently, and their results are subsequently aggregated. This segmentation reduces the complexity of any single model while maintaining high prediction reliability through the ensemble approach, and enables efficient resource utilization through parallel processing.
3Measurement precision
If conventional systems use large volumes of training data to improve model intelligence, then the classification capability improves, but the resource consumption and training time increase
Solution Approach 1:
The system performs preliminary actions by pre-training multiple embedding models on large datasets before deployment. Once trained, these models can be rapidly deployed and their results aggregated without requiring additional training time during inference. This preliminary training phase enables the ensemble system to achieve high classification accuracy while maintaining fast operation during actual use, effectively separating the time-consuming training phase from the efficient inference phase.
