Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual annotation of training data is used to train deep learning models, then model accuracy is improved, but the workload and time consumption increase significantly
Solution Approach 1:
The system performs preliminary action by using an initial model to pre-annotate training data before the main training process. This pre-annotation creates a foundation of labeled data that reduces the need for extensive manual annotation, thereby decreasing annotation time while maintaining model accuracy through subsequent refinement steps.
Solution Approach 2:
The initial model serves as an intermediary that bridges the gap between unannotated data and manually annotated data. It generates preliminary annotations that act as a mediator, reducing the burden of manual annotation while providing sufficient quality for model training, thus resolving the contradiction between accuracy and annotation time.
2Reliability
If training data is annotated manually to improve model performance, then model prediction ability is improved, but the complexity and cost of data preparation increase
Solution Approach 1:
The data preparation process is segmented into multiple stages: initial model generation, pre-annotation of training data, and selective manual annotation. This segmentation divides the complex task of full manual annotation into manageable parts, reducing overall complexity while maintaining prediction ability through the multi-stage approach.
Solution Approach 2:
The system implements self-service by enabling the initial model to automatically generate annotations for training data without requiring extensive manual intervention. This self-annotation capability reduces data preparation complexity while maintaining sufficient data quality for training, thereby preserving model prediction ability.
3Reliability
If model optimization is performed frequently to maintain prediction ability, then model performance is improved, but the time and computational resources required increase
Solution Approach 1:
The system applies periodic action by updating the model at fixed time intervals rather than continuously. This periodic optimization maintains model performance by incorporating newly generated noise data at regular intervals, while avoiding the excessive time consumption of continuous optimization, thus resolving the contradiction between performance and optimization time.
Solution Approach 2:
The system uses copying by creating updated models based on previous model versions and newly generated noise data. Instead of completely retraining from scratch, it copies and refines existing models periodically, which maintains prediction ability while significantly reducing the time and computational resources required compared to full retraining.

AI summary
A method for optimizing an image classification model can include determining a first image classification model based on initial training data; in response to model optimization, determining a second image classification model based on the first image classification model and a noise data set; and obtaining a third image classification model by optimizing the second image classification model based on the initial training data, the third image classification model being configured to update the noise data set based on noise data generated within a predetermined time period and the noise data set.
