1Measurement precision

If traditional training methods are used with paired image-text data, then training accuracy can be improved, but data acquisition difficulty and time consumption increase significantly

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-training the neural network on large-scale unpaired image-text datasets before fine-tuning on smaller paired datasets. This preliminary pre-training phase enables the model to learn general image-text representations in advance, reducing the time and data required for subsequent task-specific training while maintaining high accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism by using a dual-encoder architecture with separate image and text encoders that are initially trained independently on unpaired data. These intermediaries (independent encoders) are later combined and fine-tuned together, allowing the system to leverage both unpaired and paired data effectively while reducing overall training time.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If more training data is collected to improve model performance, then training effectiveness increases, but data processing complexity and computational resources increase

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the training process into distinct phases: pre-training on unpaired data and fine-tuning on paired data. It also segments the data into unpaired image-text sets and paired image-text sets, processing them through different training protocols. This segmentation reduces overall processing complexity while maintaining model performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by using a subset of paired data for fine-tuning after comprehensive pre-training on unpaired data. The model achieves sufficient performance with partial paired training data because the pre-training phase has already established strong general representations, reducing the need for extensive paired data processing.

Inventive Principle:
Principle #16Partial or excessive action

If paired image-text training data is used, then training speed can be improved, but data availability and acquisition ease worsen

Solution Approach 1:

The patent applies universality by designing a training framework that can process both unpaired and paired data through the same neural network architecture. The system is multi-functional, capable of performing pre-training on easily acquired unpaired data and fine-tuning on paired data, making the overall system adaptable to different data availability scenarios while maintaining efficient training.

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

Solution Approach 2:

The patent applies preliminary action by conducting pre-training on unpaired data before fine-tuning on paired data. This preliminary phase enables the model to develop robust features from readily available unpaired data, after which paired data is used only for task-specific adaptation, significantly improving overall training efficiency.

Inventive Principle:
Principle #10Preliminary action
