Solution Overview
Problem
Existing virtual assistance systems struggle to provide accurate responses to queries related to future states due to reliance on static knowledge corpuses, which often fail to account for dynamic parameters like weather and traffic conditions.

A virtual assistant system that determines the required precision and accuracy of a query, applying digital twin simulations only when necessary to enhance response accuracy, while leveraging a knowledge corpus for quicker responses when precision thresholds are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital twin simulations are always performed to ensure high precision responses, then measurement precision is improved, but productivity deteriorates due to increased computational time and resources
Solution Approach 1:
The system dynamically changes the parameter of simulation execution by introducing a confidence threshold that determines whether to perform digital twin simulations. When the knowledge corpus confidence score exceeds the threshold, simulations are skipped; when it falls below, simulations are executed. This parameter-based decision mechanism resolves the contradiction by adapting the computational intensity to the specific query requirements.
Solution Approach 2:
Instead of always performing full digital twin simulations, the system applies partial action by selectively executing simulations only for queries that fall below the confidence threshold. This partial execution approach maintains high precision for uncertain queries while avoiding unnecessary computational overhead for confident queries, thereby balancing precision and productivity.
2Reliability
If digital twin simulations are performed for all queries, then reliability is improved, but use of energy worsens due to increased computational demands
Solution Approach 1:
The system changes the operational parameter by using a confidence threshold to control simulation execution. This parameter-based gating mechanism ensures simulations are performed only when necessary (low confidence cases), maintaining reliability for critical queries while significantly reducing overall energy consumption compared to universal simulation execution.
Solution Approach 2:
The system extracts and separates the simulation execution decision from the general query processing flow by introducing a confidence threshold filter. This extraction allows the system to identify and process only those queries that require simulation, taking out the energy-intensive simulation step from the routine processing path and applying it selectively, thereby reducing total energy usage while preserving reliability where needed.
3Productivity
If digital twin simulations are selectively applied based on confidence thresholds, then productivity is improved, but measurement precision may worsen for queries below the threshold
Solution Approach 1:
The system introduces an intermediary mechanism - the confidence threshold evaluation - that mediates between the knowledge corpus and digital twin simulation. This intermediary assesses the reliability of knowledge corpus responses and selectively triggers simulations only when needed, ensuring that precision is maintained for uncertain queries while productivity is improved by avoiding unnecessary simulations for confident queries.
Solution Approach 2:
The system implements a feedback loop where the confidence score from the knowledge corpus feeds into the decision-making process. This feedback mechanism allows the system to continuously adjust its response strategy based on the reliability of available information, ensuring that simulations are triggered only when the feedback indicates insufficient confidence, thereby maintaining precision while improving overall productivity.
Data Source
AI summary
Computer technology that receives a query and a desired level of precision and/or accuracy (herein, a “p/a value”) associated with the received query, determines whether the p/a value exceeds a predetermined threshold, if the p/a value exceeds the predetermined threshold, then the virtual assistant system applies digital twin simulation to a digital twin data set in determining the query response to improve precision and/or accuracy of the query response, and outputs the query response to the querying party (for example, output as sound data in a voice assistant system). If the p/a value is below the threshold value, then the digital twin simulation is not performed, which makes the response quicker and puts less computational power demands on the virtual assistant system. In some embodiments, the virtual assistant system calculates the p/a value based on context.
