Engineering Contradiction Analysis
1Measurement precision
If conventional subjective estimation methods are used for forecasting task completion, then the process is simple and easy to operate, but the accuracy and reliability of predictions deteriorate
Solution Approach 1:
The patent replaces the mechanical/manual system of subjective human estimation with an automated machine learning system that uses historical data and algorithms to predict task completion. This substitution transforms the forecasting process from opinion-based to data-driven, significantly improving prediction accuracy while managing system complexity through automated model selection and maintenance.
Solution Approach 2:
The machine learning system performs self-evaluation and self-selection of models. The system automatically evaluates multiple predictive models, selects the best-performing one based on accuracy metrics, and maintains the library of models without requiring manual intervention. This self-service capability improves prediction reliability while keeping the operational process simple for users.
2Measurement precision
If multiple predictive models are maintained and evaluated, then prediction accuracy improves, but computational resources and processing time increase
Solution Approach 1:
The system performs preliminary evaluation and selection of predictive models in advance, maintaining a library of pre-evaluated models. When a prediction is needed, the system quickly selects from pre-vetted models rather than evaluating multiple models from scratch each time. This preliminary action reduces real-time computational resource consumption while maintaining high prediction accuracy.
Solution Approach 2:
The system dynamically adjusts parameters such as model selection criteria, evaluation metrics, and data weighting based on performance feedback. By changing these parameters optimally, the system achieves high prediction accuracy with reduced computational overhead, as the model selection and maintenance processes are optimized to balance accuracy with resource efficiency.
3Productivity
If machine learning models are used for task completion forecasting, then forecasting efficiency improves, but the complexity of model selection and maintenance increases
Solution Approach 1:
The system implements self-service capabilities where the machine learning framework automatically evaluates, selects, and maintains predictive models without requiring manual intervention. The system autonomously manages the complexity of model selection and maintenance, allowing users to benefit from high forecasting efficiency without needing to understand or manage the underlying model complexity.
Solution Approach 2:
The system incorporates feedback mechanisms that continuously evaluate model performance and automatically adjust model selection and maintenance strategies. This feedback loop enables the system to manage model complexity dynamically, selecting appropriate models based on current performance metrics and automatically handling maintenance tasks, thereby improving forecasting efficiency while keeping model management transparent and automated.
Data Source
AI summary
A request is received for determining a task completion rate of each of a first set of tasks associated with a set of task attributes. The first set of tasks are scheduled to be completed within a first timer period. An MAPE score is calculated or obtained for each of the completion rate predictive models, which is determined based on prior predictions performed in a second time period in the past. The duration of the second time period is a multiple of the first time period. One of the predictive models is selected based on the MAPE scores of the predictive models, where the selected model has the lowest MAPE score amongst the predictive models in the set. In another embodiment, a predictive model is selected further based on the volatility scores of the predictive models. A model with a combination of lowest MAPE score and volatility score is selected.
