1Productivity
If traditional optimization methods are used in high-dimensional search spaces, then compute time increases, but the ability to find optimal design candidates deteriorates
Solution Approach 1:
The patent introduces a large language model as an intermediary between the design parameters and the forward model. The LLM processes design scenarios and generates optimized parameters, acting as a mediator that reduces the computational burden of direct high-dimensional optimization while maintaining solution quality. This intermediary layer enables faster convergence to optimal designs without sacrificing effectiveness.
2Measurement precision
If historical data is used to build probability distributions, then modeling accuracy improves, but reliability deteriorates when data is not representative or parameters are interdependent
Solution Approach 1:
The patent transforms the approach to probability distribution modeling by using a large language model to generate and adjust distribution parameters dynamically. Instead of relying solely on historical data to estimate parameters, the LLM adapts parameters based on the specific design scenario and constraints, enabling accurate representation of interdependent parameters even when historical data is limited or unrepresentative.
3Manufacturing precision
If the search space is explored exhaustively, then design candidate quality improves, but compute time increases beyond acceptable limits
Solution Approach 1:
The patent applies preliminary action by using the large language model to pre-process design scenarios and generate initial optimized parameter sets before formal optimization begins. The LLM's semantic understanding allows it to predict promising regions of the search space, enabling the optimizer to focus computational resources on high-potential areas rather than exhaustively searching the entire space.
4Measurement precision
If domain expertise is incorporated through LLM tailoring, then modeling accuracy improves, but system complexity increases
Solution Approach 1:
The patent implements dynamic adaptability by making the LLM tailoring process adjustable based on the specific application needs. The system can dynamically select the degree of customization, choosing between pre-trained models for standard applications and fine-tuned models for specialized domains. This dynamic approach allows the system to balance accuracy requirements against computational complexity and resource constraints.

AI summary
An inverse design system combines a large language model (LLM) with a task-specific optimizer, which includes a search function, a forward model, and a comparator. The LLM adjusts parameters of the optimizer's components in response to a design scenario. Then the optimizer processes the design scenario to produce design candidates. Optionally, the LLM learns from the design candidates in an iterative process. A stochastic predictive modeling system combines an LLM with input distributions and a forward model. The LLM adjusts one or more of the input distributions and/or the forward model in response to a forecast scenario. Then the forward model processes a sampling of the input distributions to produce a forward distribution. Optionally, the LLM informs the sampling process. Optionally, the LLM learns from the forward distribution.
