Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The implementation of machine learning with high accuracy requires a large amount of high-accuracy data, which is time-consuming and costly to create, and the accuracy can vary depending on the skill of the data creator.
Innovation Solution
An information processing device that adds temporary labels to input data, allows for correction by a person in charge of labeling, and calculates labeling accuracy by comparing the corrected labels with pre-existing correct-answer labels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual labeling is performed by persons in charge of labeling, then high-accuracy data sets can be created for machine learning, but huge time cost and human cost are required
Solution Approach 1:
The system performs preliminary labeling using machine learning models to generate initial label data before human reviewers process it. This preliminary action reduces the overall time cost by handling routine labeling tasks automatically, while human reviewers only need to verify and correct the pre-labeled data rather than creating labels from scratch.
Solution Approach 2:
The system introduces an intermediary evaluation mechanism that automatically assesses the quality of label data and provides feedback to guide human reviewers. This intermediary layer optimizes the workflow by identifying which labels need human attention and which can be accepted as-is, thereby reducing the time cost while maintaining high labeling accuracy.
2Measurement precision
If manual labeling is performed by persons in charge of labeling, then high-accuracy data sets can be created for machine learning, but huge human cost is required
Solution Approach 1:
The system enables self-service labeling through automated machine learning models that can independently generate label data without human intervention for straightforward cases. This self-service capability significantly reduces the quantity of human resources required, as the system handles the majority of labeling tasks autonomously while maintaining high accuracy through automated quality evaluation.
Solution Approach 2:
An automated evaluation mechanism serves as an intermediary between raw data and final labeled output, filtering and validating labels before they reach human reviewers. This intermediary process reduces the quantity of human resources needed by pre-processing and quality-checking label data automatically, allowing human reviewers to focus only on complex or ambiguous cases.
3Measurement precision
If temporary labels are added and corrected by persons in charge of labeling, then labeling accuracy can be evaluated and improved, but the process complexity increases
Solution Approach 1:
The system implements a feedback mechanism where label data is automatically evaluated against ground truth or quality standards, and evaluation results are fed back to guide the labeling process. This feedback loop improves labeling accuracy by identifying errors and guiding corrections, while the automated nature of the feedback process prevents excessive increase in process complexity.
Solution Approach 2:
The system replaces manual quality assessment and evaluation processes with automated computational mechanisms. Instead of humans manually reviewing and evaluating each label, machine learning models and automated evaluation algorithms perform these tasks, improving labeling accuracy while preventing process complexity from increasing due to manual intervention overhead.
