Surrogate Models for Spatiotemporal Data Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spatiotemporal data sets are large and expensive to store and distribute, making it challenging for end users to process them efficiently, especially over networks with low bandwidth.
Innovation Solution
A computer-implemented method generates surrogate models using machine learning algorithms to interpolate and extrapolate spatiotemporal data, allowing users to reconstruct datasets locally without transferring the full data set, by leveraging domain limits and support datasets to create interpolation, representation, and generalization models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spatiotemporal datasets are stored and distributed to end users, then data access and processing capability are improved, but storage costs and distribution costs increase significantly
Solution Approach 1:
The patent creates surrogate models as simplified copies of the original spatiotemporal datasets. These surrogate models capture the essential patterns and relationships of the data without requiring distribution of the full dataset. The surrogate models can be distributed to end users, who can then locally reconstruct or approximate the original data, significantly reducing the volume of data that needs to be stored and transmitted while maintaining data access capability.
2Measurement precision
If full spatiotemporal datasets are transmitted over networks, then data fidelity is maintained, but bandwidth requirements and transmission time increase
Solution Approach 1:
The patent extracts the essential patterns, relationships, and key information from the full spatiotemporal datasets to create compact surrogate models. These surrogate models contain only the critical information needed to reconstruct or approximate the original data, eliminating redundant or less important data elements. This extraction process maintains sufficient data fidelity for most applications while dramatically reducing the amount of data that needs to be transmitted over networks.
3Manufacturing precision
If high-resolution spatiotemporal data is provided to all users, then analysis accuracy is improved, but storage and distribution costs increase
Solution Approach 1:
The patent enables end users to reconstruct or approximate high-resolution spatiotemporal data locally on their own devices using the distributed surrogate models. Instead of providing all users with identical high-resolution datasets (which would be expensive to distribute), each user can generate the data they need locally based on their specific analysis requirements. This approach maintains analysis accuracy where needed while significantly reducing distribution costs.
Data Source
AI summary
Computer implemented methods, systems, and computer program products include program code executing on a processor(s) that identifies, in the target dataset, domain limits and resolution, wherein the domain limits comprise as upper domain limit and a lower domain limit. The processors select one or more support datasets for the target dataset and utilize the support datasets to devise an interpolation model of the target dataset for data points missing between the domain limits in the resolution. The processors generate a representation model of the target dataset between the domain limits and utilize the support dataset to generate a generalization model of the target dataset by utilizing the support datasets to extrapolate values beyond the domain limits.
