Solution Overview

Problem

Current automated data analysis systems require human intervention to determine the relative importance and reliability of different data sets, such as visual and x-ray images, which limits their ability to perform comparative analysis across various applications like geology, medicine, and finance.

Innovation Solution

The Automated Global Feature Analyzer (AGFA) uses feature vectors to represent data from various sources, normalizes these vectors, clusters them, applies principal component analysis, and calculates flag values to enable automated comparative analysis and anomaly detection, allowing for automatic analysis of data regardless of its origin.

1Productivity

If automated data analysis systems are implemented, then productivity and efficiency are improved, but the system requires human intervention to determine relative importance and reliability of data sets, which increases device complexity and reduces extent of automation

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The patent transforms qualitative data characteristics (importance, reliability) into quantitative parameters through normalization processes. Feature vectors are converted to standardized ranges (0-1) using min-max normalization, allowing automated comparison across diverse data types. This parameter transformation enables the system to automatically determine data reliability and importance without human intervention, resolving the contradiction between automation extent and system capability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces feature vectors as intermediary representations between raw data and analysis results. These vectors serve as a universal language that translates diverse data types (visual images, x-ray images, geological data, financial data) into a common format. The intermediary feature vectors enable automated comparative analysis across different applications and data sources, eliminating the need for human judgment while maintaining analysis quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple data sets from various sources are analyzed, then adaptability and versatility are improved, but the complexity of determining relative importance and reliability across different data types increases device complexity

Engineering Contradiction:
Improvecross-application data analysis capabilityVSAvoiddata processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal data representation framework using feature vectors that can handle multiple data types and applications simultaneously. The same normalization and clustering algorithms are applied across diverse domains including geology, medicine, and finance. This universal approach allows the system to adapt to different applications without increasing complexity, as the core processing mechanism remains consistent across all use cases.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent standardizes diverse data parameters through normalization to common ranges (0-1). By converting features from different data sources (visual images, x-ray images, sensor data) into standardized parameter formats, the system eliminates the complexity of handling heterogeneous data types. The parameter transformation process creates a unified framework that simplifies cross-application analysis while maintaining the ability to handle diverse data sources.

Inventive Principle:

3Measurement precision

If feature vectors are normalized and clustered with multiple processing steps, then measurement precision and anomaly detection accuracy are improved, but the computational time and device complexity increase

Engineering Contradiction:
Improveanomaly detection accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary normalization to feature vectors before clustering and anomaly detection. By pre-processing data to standardize ranges and distributions, the system prepares data for more efficient processing in subsequent steps. This preliminary action reduces the computational burden during clustering and anomaly detection, as the data is already in an optimized format that requires less intensive processing to achieve high precision results.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent divides the data processing into distinct segments: feature extraction, normalization, clustering, and anomaly detection. Each segment handles a specific aspect of the analysis independently. This segmentation allows for optimized processing in each stage, where normalization prepares data efficiently, clustering groups similar features quickly, and anomaly detection operates on pre-organized data. The segmented approach reduces overall computational time compared to unoptimized monolithic processing while maintaining high measurement precision.

Inventive Principle:
Principle #1Segmentation
