Automatic Pattern Detection in Datasets via Decision Tree Ranking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Business Intelligence (BI) tools require users to manually select attributes for analysis, leading to an error-prone and time-consuming process, and are often too complex for ordinary business users, especially when dealing with large datasets, and lack real-time analysis capabilities.
Innovation Solution
The development of techniques for automatic detection of statistically significant attribute combinations in datasets, using decision trees to rank and visualize patterns, allowing for 'What if' analysis and reverse inference, with a focus on reducing complexity and enabling near-real-time decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually select attributes for analysis in existing BI tools, then analysis depth and customization can be achieved, but the process becomes error-prone and time-consuming
Solution Approach 1:
The system performs automatic attribute selection and pattern detection without requiring manual user intervention. The algorithm autonomously identifies statistically significant attribute combinations, ranks them by importance, and generates visualizations, allowing the system to serve itself rather than requiring users to manually configure each analysis parameter.
Solution Approach 2:
The system pre-computes and stores statistical significance metrics for all attribute combinations before user queries. By performing preliminary analysis to identify and rank significant patterns in advance, the system reduces the time required for actual user analysis while maintaining high accuracy through pre-validated statistical relationships.
2Ease of operation
If BI tools provide guided navigation interfaces, then ease of use is improved, but the ability to perform deep statistical analysis and reverse inference is limited
Solution Approach 1:
The system provides a unified interface that simultaneously supports multiple analysis modes including forward inference, reverse inference, and what-if analysis. The same decision tree structure and statistical framework handle diverse query types, allowing users to perform comprehensive statistical analysis through a single accessible interface rather than requiring separate tools for different analysis types.
3Adaptability or versatility
If statistical modeling tools are made available to business users, then analytical power is increased, but the complexity and specialized knowledge required increases
Solution Approach 1:
The system extracts and automates the complex statistical modeling steps, separating the sophisticated algorithmic processing from user interaction. The complex decision tree generation, statistical significance testing, and pattern recognition are performed automatically by the system, while users interact with simplified visualizations and high-level queries, effectively removing complexity from the user-facing interface while retaining advanced analytical capabilities.
4Speed
If BI tools move to departmental deployments with business user control, then real-time analysis capability is improved, but the complexity of data management and analysis increases
Solution Approach 1:
The system segments the data analysis process into independent, modular components including attribute combination generation, statistical significance testing, decision tree construction, and visualization. This segmentation allows each component to be optimized independently and enables parallel processing of different analysis tasks, improving real-time performance while reducing overall system complexity through clear separation of concerns.

AI summary
Techniques allow automatic identification of statistically significant attribute combinations in a dataset, and provide users with an understanding thereof including starting points for further analysis. Statistically significant combinations may be obtained from large data sets by limiting combinations to four or fewer attributes. The combinations obtained may be ranked to differentiate patterns, e.g. according to factors such as error ratio, decision tree depth, occurrences, and number of attributes. Still further insights may be achieved by ranking attributes according to the number of statistically significant combinations in which they appear. For useful visualization of statistically significant information within the patterns, only those having at least one measure/numeric may analyzed for further insight (e.g. by an outlier algorithm) and presented as output in a chart (e.g. pie, bar) form. The decision tree approach of various embodiments may facilitate ‘What if’ analysis of the data, as well as obtaining the reverse inference.
