Solution Overview
Problem
Current methods for representing words and phrases as vectors in natural language processing face challenges in determining similarity, as each method has its own drawbacks, and existing systems often rely solely on supervised or unsupervised learning without applying semi-supervised approaches.
Innovation Solution
The method involves generating vector representations for natural language text using an artificial neural network trained with both supervised and unsupervised learning methods, combining initial vector representations, first metadata generated through supervised learning, and second metadata generated through unsupervised learning to improve the neural network's ability to generate accurate vector representations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only supervised learning methods are used to generate metadata for training, then the accuracy of vector representations can be improved with labeled data, but the complexity of data preparation and labeling increases significantly
Solution Approach 1:
The patent combines supervised learning (first metadata from labeled data) and unsupervised learning (second metadata from unlabeled data) into a unified training framework. The neural network is trained using both types of metadata simultaneously, merging the advantages of labeled accuracy with the scalability of unlabeled data processing.
Solution Approach 2:
The training system is designed to handle multiple types of data (labeled and unlabeled) and multiple learning objectives (supervised and unsupervised tasks) within a single unified framework. The neural network performs multiple functions: learning from labeled metadata for accuracy and from unlabeled metadata for generalization, making the system universally applicable to various data scenarios.
2Productivity
If only unsupervised learning methods are used to generate metadata for training, then the scalability to large datasets can be improved, but the precision and reliability of vector representations deteriorates
Solution Approach 1:
The patent merges unsupervised learning (second metadata from unlabeled data) with supervised learning (first metadata from labeled data). This combination allows the system to scale to large datasets using unsupervised methods while maintaining precision through the incorporation of labeled data, resolving the trade-off between scalability and precision.
Solution Approach 2:
The training approach uses a composite learning strategy that combines two different learning paradigms (supervised and unsupervised) into a single training process. Just as composite materials combine different materials to achieve superior properties, this composite learning approach combines the scalability of unsupervised learning with the precision of supervised learning.
3Measurement precision
If a semi-supervised learning approach combining both supervised and unsupervised methods is used, then the accuracy and scalability can be improved simultaneously, but the training process complexity and computational resources increase
Solution Approach 1:
The patent segments the training process into distinct components: generating first metadata through supervised learning, generating second metadata through unsupervised learning, and training the neural network using both types of metadata. This segmentation allows each component to be optimized independently while maintaining overall system accuracy and manageability.
Solution Approach 2:
The training system dynamically balances the use of supervised and unsupervised learning based on data availability and task requirements. The framework can adaptively adjust the proportion of labeled versus unlabeled data used during training, providing dynamic flexibility to optimize performance while managing computational complexity.
