Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attribute correlation techniques in telecommunications, particularly indirect correlation, struggle to efficiently model latent factors and handle diverse business needs, often requiring assumptions about correlation types and failing to leverage small example sets effectively.
Innovation Solution
A meta-correlation method that represents attribute pairs as nodes in a graph, using various correlation techniques to generate feature vectors and models latent factors, allowing for the maximization of correlation scores between labeled pairs and minimization of uncorrelated scores, while incorporating small example sets and extending to handle multiple correlations and attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If indirect correlation techniques are used to capture latent factors, then the ability to model hidden relationships is improved, but the complexity of the correlation model increases and assumptions about correlation types are required
Solution Approach 1:
The patent applies a unified meta-learning framework that can handle multiple correlation types (linear, non-linear, value-based, rank-based, pair-wise, list-wise) through a single model architecture. This universal approach eliminates the need for separate models for different correlation types, reducing overall system complexity while maintaining the ability to capture various latent factors.
Solution Approach 2:
The patent dynamically adjusts correlation parameters and model configurations based on the specific business case and data characteristics. By making the model adaptable through parameter changes rather than fixed assumptions, it reduces complexity while maintaining high detection accuracy for latent factors.
2Adaptability or versatility
If existing correlation approaches are used, then the implementation is simpler, but they fail to leverage small example sets and cannot handle diverse business needs
Solution Approach 1:
The patent performs preliminary analysis and feature engineering on small example sets before applying the correlation model. By preprocessing and extracting meaningful features from limited data in advance, it maximizes the utilization of small example sets and enables the model to handle diverse business needs effectively.
Solution Approach 2:
The patent employs a dynamic meta-learning framework that can adapt to different business scenarios and data characteristics. The model dynamically adjusts its parameters and structure based on the specific business needs, enabling it to leverage small example sets effectively while maintaining versatility across different applications.
3Measurement precision
If multiple correlation techniques are integrated, then the coverage of latent factors is improved, but the computational complexity and model tuning requirements increase
Solution Approach 1:
The patent merges multiple correlation techniques (linear, non-linear, value-based, rank-based, pair-wise, list-wise) into a single integrated meta-learning model. By combining these techniques uniformly rather than separately, it improves latent factor capture while reducing the overall tuning complexity through centralized model management.
4Adaptability or versatility
If traditional correlation methods are used, then the computational resources required are lower, but they cannot handle multiple attributes and grades of correlation
Solution Approach 1:
The patent segments the correlation analysis into hierarchical levels, handling different grades of correlation (low, medium, high) and multiple attributes through a structured meta-learning approach. This segmentation enables the model to process complex multi-attribute correlations efficiently by breaking them down into manageable components, balancing computational resource usage with enhanced versatility.

AI summary
The formulation of meta-correlation method as a graph based problem is disclosed. The meta-correlation method utilizes one or more correlation techniques, and also captures latent factors critical for the business utility in hand is described. The method also leverages a small example set to bootstrap for the target utility case. The proposed method can easily work for attribute groups of any size, not just attribute groups consisting of pairs of attributes.
