1Reliability

If traditional machine learning models are used to achieve high performance in analyzing complicated problems, then the model accuracy and analytical capability are improved, but the transparency and interpretability of the model deteriorate, making it difficult for users to understand the output recommendations

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces tropical geometry as an intermediary framework that bridges the gap between complex machine learning models and human-understandable interpretations. By representing model decisions through tropical geometric structures (such as tropical polynomials and their associated graphs), the system maintains high predictive accuracy while providing visual and mathematical representations that are interpretable to users. The tropical geometry acts as a mediator that preserves the computational power of complex models while translating their outputs into understandable forms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms the parameter representation of machine learning models by applying tropical geometry transformations. Traditional model parameters are converted into tropical coordinates and structures, which maintain the mathematical relationships necessary for accurate predictions while creating a new parameter space that is more amenable to interpretation. This parameter transformation allows the model to retain its high performance while operating in a representation that reveals structural insights about decision-making processes.

2Measurement precision

If precise annotated data is used for training machine learning models, then the model training accuracy is improved, but the ability to handle approximate or fuzzy rules that human experts use deteriorates, limiting the model's capability to analyze complex problems the way humans do

Engineering Contradiction:

Solution Approach 1:

The patent applies dynamics by making the training approach flexible and adaptive rather than static. The system dynamically adjusts between using precise annotated data and incorporating fuzzy rules based on the problem context. The tropical geometry framework enables the model to handle both precise and approximate information seamlessly, allowing the training process to adapt to the nature of the input data and the requirements of the classification task. This dynamic capability allows the model to leverage human expert knowledge in the form of fuzzy rules while maintaining the benefits of precise training data when available.

Inventive Principle:

3Reliability

If traditional machine learning models require precise annotated data for training, then the training process becomes more rigorous, but the productivity and speed of model development deteriorate due to the difficulty of obtaining and annotating precise data

Engineering Contradiction:

Solution Approach 1:

The patent employs copying by creating synthetic training data and rules based on existing knowledge and patterns. Instead of requiring extensive manual annotation of precise data, the system generates training examples by copying and transforming existing fuzzy rules and domain knowledge. This approach maintains training rigor by ensuring that the synthetic data preserves the essential characteristics and relationships needed for accurate learning, while dramatically reducing the time and resources required for data preparation and annotation.

Inventive Principle:
Principle #26Copying

AI summary

A method for denoising magnetic resonance images and data is disclosed herein. An example method includes receiving a series of MRF images from a scanning device; identifying one or more subsets of voxels for the series of MRF images; generating one or more sets of eigenvectors, each set of the one or more sets of eigenvectors corresponding to one of the one or more subsets of voxels, and each eigenvector of the one or more sets of eigenvectors having a corresponding eigenvalue; applying a noise distribution model to each of the eigenvalues; identifying a subset of the eigenvalues as corresponding to noise based on the noise distribution model; and reconstructing the series of MRF images without the subset of eigenvalues identified as corresponding to noise.
