Solution Overview

Problem

Existing AIGC models struggle to accurately understand user desires expressed through multimodal information such as speech and video, leading to low matching between generated responses and user intentions, which reduces interaction efficiency and user experience.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If existing AIGC models process multimodal information to generate responses, then the system can provide automated interactions, but the accuracy of understanding user desires and matching responses to user intentions deteriorates

Engineering Contradiction:
Improveautomated interactionVSAvoidaccuracy of understanding user desires
Core Design Contradiction:
Extent of automationVSMeasurement precision

Solution Approach 1:

The model segments the response generation process into distinct stages: understanding user desires from multimodal input, generating candidate response words, and selecting target response words through attention fusion. This segmentation allows each stage to be optimized independently, improving overall accuracy while maintaining automation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an attention fusion layer as an intermediary mechanism between the speech recognition features and the response word selection. This intermediary processes and aligns deep semantic features, enabling more accurate matching between user intentions and generated responses while preserving automated interaction capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If existing AIGC models generate responses based on multimodal input, then interaction speed is maintained, but the matching degree between responses and user intentions deteriorates

Engineering Contradiction:
Improveinteraction speedVSAvoidmatching degree between responses and user intentions
Core Design Contradiction:
SpeedVSManufacturing precision

Solution Approach 1:

The model performs preliminary processing of speech recognition features to extract deep semantic representations before response word generation. By preparing the semantic understanding in advance through the attention fusion layer, the system can quickly generate accurate responses without sacrificing interaction speed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent transforms the speech recognition features into aligned deep semantic features through the attention fusion mechanism. This parameter transformation enables the model to maintain fast interaction while significantly improving the matching degree between responses and user intentions by changing how semantic information is represented and processed.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If the large model uses attention fusion layer to align deep semantic features, then the accuracy of response text generation is improved, but the computational complexity increases

Engineering Contradiction:
Improveaccuracy of response text generationVSAvoidcomputational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The attention fusion layer applies local quality enhancement by focusing computational resources on aligning specific deep semantic features that are most critical for response accuracy. Rather than uniformly processing all features, the mechanism identifies and prioritizes key semantic alignments, improving accuracy while managing computational complexity.

Inventive Principle:
Principle #3Local quality

4Reliability

If the model processes speech recognition features through attention fusion layer, then hallucinations are reduced, but the processing time increases

Engineering Contradiction:
Improvereduction of hallucinationsVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The attention fusion mechanism incorporates feedback loops that continuously align generated response words with the original speech recognition features. This feedback ensures that responses remain faithful to user intentions, reducing hallucinations. The iterative alignment process is optimized to minimize additional processing time while maintaining high reliability.

Inventive Principle:
Principle #23Feedback
