Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If only package attribute information is used for feature extraction, then the extraction process is simple, but the accuracy and reliability of user behavior analysis deteriorates

Engineering Contradiction:
Improveaccuracy of feature information extractionVSAvoidcomplexity of extraction process
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the feature extraction process into two distinct stages: first extracting package attribute information, then extracting user attribute information. This segmentation allows the system to incorporate multiple information sources for improved accuracy while maintaining a structured and manageable extraction process, resolving the contradiction between comprehensive analysis and process simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges package attribute information and user attribute information through a fusion mechanism that combines both data sources. This merging enables the system to achieve higher measurement precision by considering both what packages users buy and user-specific characteristics, while the structured combination approach keeps the overall system complexity可控.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If traditional counting methods are used to extract feature information, then the processing speed is fast, but the reliability of user behavior classification deteriorates

Engineering Contradiction:
Improvereliability of user behavior classificationVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent performs preliminary extraction of user attributes (such as user ID, level, and other characteristic features) before the main classification process. This preliminary action prepares the data in advance, enabling more reliable user behavior classification while maintaining processing efficiency through pre-organized information structures.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical counting methods with an information fusion approach that incorporates machine learning techniques. This substitution improves reliability by considering multiple factors beyond simple package counts, including user-specific attributes and behavioral patterns, while the automated nature of the fusion process maintains high processing efficiency.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If comprehensive user and package attributes are analyzed, then the classification accuracy improves, but the computational resources and time required increases

Engineering Contradiction:
Improveclassification accuracyVSAvoidfeature extraction time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent segments the comprehensive attribute analysis into distinct modules: package attribute extraction, user attribute extraction, and information fusion. This segmentation allows parallel processing of different attribute types, reducing overall extraction time while maintaining comprehensive analysis for high classification accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a flexible information fusion mechanism that can adaptively select which user and package attributes to analyze based on the specific classification task. This partial action approach ensures comprehensive analysis when needed for high accuracy, while allowing selective reduction of analyzed attributes when processing time is constrained, thus balancing accuracy and time requirements.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

This application relates to a feature information extraction method and apparatus, a server cluster, and a storage medium. In various implementations, package attribute vectors respectively corresponding to at least two virtual item packages of a target object may be obtained. Feature extraction may be performed on these package attribute vectors to obtain feature vectors. Using the feature vector feature information may be obtained for the virtual item packages. In this way, differences between users of different attributes when the users are using virtual item packages may be considered, thereby improving the accuracy, efficiency and security of feature information extraction.
