Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data construction is used to teach neural networks insufficient knowledge, then knowledge can be increased, but time and cost consumption increases significantly
Solution Approach 1:
The neural network autonomously identifies knowledge gaps through uncertainty calculation and generates training data independently without human intervention. The system calculates uncertainty of current knowledge, determines insufficient knowledge areas, generates synthetic training data through the generative model, and performs self-training to increase knowledge autonomously.
Solution Approach 2:
The system implements a feedback loop where the neural network calculates uncertainty of its current knowledge representation, identifies knowledge insufficiency, generates targeted training data based on this uncertainty assessment, and uses this data to improve its knowledge representation in subsequent iterations.
2Reliability
If manual data construction is used to teach neural networks insufficient knowledge, then knowledge can be increased, but cost increases significantly
Solution Approach 1:
The neural network autonomously identifies knowledge gaps through uncertainty calculation and generates training data independently without human intervention. The system calculates uncertainty of current knowledge, determines insufficient knowledge areas, generates synthetic training data through the generative model, and performs self-training to increase knowledge autonomously.
Solution Approach 2:
Instead of collecting real-world data through expensive manual processes, the system creates synthetic copies of training data by generating new data samples from learned representations. The generative model creates artificial training examples that replicate the structure and patterns of real data without requiring actual human annotation or data collection.
3Adaptability or versatility
If deep learning-based neural networks are used, then high-level abstraction from data is achieved, but autonomous determination of knowledge insufficiency is not possible
Solution Approach 1:
The system implements a feedback loop where the neural network calculates uncertainty of its current knowledge representation, identifies knowledge insufficiency, generates targeted training data based on this uncertainty assessment, and uses this data to improve its knowledge representation in subsequent iterations.
Solution Approach 2:
The system introduces uncertainty as a new parameter in the neural network's operational framework. By calculating uncertainty metrics alongside traditional accuracy measures, the system enables the network to automatically detect when its knowledge representation is insufficient and trigger data generation processes accordingly.
Data Source
AI summary
A knowledge increasing method includes calculating uncertainty of knowledge obtained from a neural network using an explicit memory, determining the insufficiency of the knowledge on the basis of the calculated uncertainty, obtaining additional data (learning data) for increasing insufficient knowledge, and training the neural network by using the additional data to autonomously increase knowledge.
