Solution Overview

Problem

Existing multivariate learning and optimization techniques struggle to efficiently identify and utilize causal relationships between process decisions and outcomes in complex, dynamic systems, often requiring extensive a priori knowledge and being limited by adaptive experimentation's sequential nature.

Innovation Solution

The system employs self-organized experimental units (SOEUs) generated based on assumptions, which are repeatedly injected into the system to quantify inferences and iteratively modified to identify causal interactions, enabling continuous optimization and decision-making under uncertainty.

Engineering Contradictions & Design Principles

1Reliability

If adaptive experimentation is used to identify causal relationships, then decision-making under uncertainty is enabled, but the sequential nature limits efficiency and speed of optimization

Engineering Contradiction:
Improvecausal relationship identificationVSAvoidoptimization speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary actions by generating multiple self-organized experimental units (SOEUs) in advance and injecting them into the system simultaneously rather than sequentially. This allows causal relationships to be identified through parallel experimentation, dramatically increasing optimization speed while maintaining reliability through the use of confidence intervals and iterative modification of SOEUs.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If extensive a priori knowledge is required for multivariate learning, then accurate causal inference can be achieved, but system complexity and implementation difficulty increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system employs self-organized experimental units that automatically generate and structure their own experimental designs without requiring extensive a priori knowledge from users. The SOEUs self-organize to identify causal relationships, reducing implementation complexity while maintaining inference accuracy through automated confidence interval calculation and iterative refinement.

Inventive Principle:
Principle #25Self-service

3Loss of information

If continuous monitoring and optimization is implemented, then real-time causal understanding is achieved, but computational resources and processing time increase

Engineering Contradiction:
Improvereal-time causal understandingVSAvoidcomputational resource consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The system implements continuous monitoring and optimization through the iterative injection and modification of self-organized experimental units. Rather than performing discrete, resource-intensive analyses, the SOEUs continuously adapt and refine causal inference in real-time, reducing peak computational demands while maintaining continuous causal understanding through streamlined processing pipelines.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A system and methods for multivariant learning and optimization repeatedly generate self-organized experimental units (SOEUs) based on the one or more assumptions for a randomized multivariate comparison of process decisions to be provided to users of a system. The SOEUs are injected into the system to generate quantified inferences about the process decisions. Responsive to injecting the SOEUs, at least one confidence interval is identified within the quantified inferences, and the SOEUs are iteratively modified based on the at least one confidence interval to identify at least one causal interaction of the process decisions within the system. The causal interaction can be used for testing, diagnosis, and optimization of the system performance.
