Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing market research methods struggle to accurately determine causal effects in marketing campaigns due to non-random assignment of subjects, leading to biased results and high computational costs, especially when analyzing treatment and control group datasets.
Innovation Solution
A method that utilizes an analysis engine to independently process treatment and control group datasets simultaneously, employing entropy balancing and weighting techniques to minimize bias and reduce computational burden, allowing for efficient determination of causal effects without requiring separate processing cycles.

Engineering Contradiction Analysis
1Productivity
If separate processing cycles are used for treatment and control group datasets, then processing can be performed sequentially, but computational costs increase and processing time extends
Solution Approach 1:
The patent merges the processing of treatment and control group datasets into a single simultaneous processing cycle. The analysis engine processes both datasets concurrently using the same computational resources, eliminating the need for sequential processing cycles and reducing overall computational time and costs while maintaining processing accuracy.
2Measurement precision
If traditional causal effect analysis methods are used, then market research can be performed, but biased results occur due to non-random assignment of subjects
Solution Approach 1:
The patent changes the analytical parameters by introducing entropy balancing weights that adjust the treatment and control group datasets to account for non-random assignment. The system calculates weights based on observed covariates and uses these weights to create balanced comparisons, eliminating bias while maintaining measurement precision of causal effects.
3Measurement precision
If complex statistical methods are applied to determine causal effects, then measurement precision can improve, but computational costs and complexity increase
Solution Approach 1:
The patent replaces complex traditional statistical methods with an entropy balancing approach that uses information theory concepts. Instead of relying on complex multivariate regression or instrumental variable methods, the system uses entropy minimization to calculate balancing weights, simplifying the computational mechanics while maintaining or improving measurement precision.
