Solution Overview
Problem
Existing time series forecasting methods lack domain independence and efficiency at a production scale, failing to effectively handle various patterns across different domains and granularities, leading to suboptimal decision-making and increased data storage and computation time.
Innovation Solution
A configuration-free, domain-independent time series forecasting engine is developed, integrating diagnostic techniques and performance indicators to seamlessly handle any time series, using refinement strategies, behavioral diagnostics, and ensemble modeling to select the best-fit models for trend, seasonality, and randomness, enabling zero-configuration workflow and high accuracy across domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If domain-specific forecasting methods are used, then forecasting accuracy for specific domains is improved, but adaptability to handle different domains and granularities deteriorates
Solution Approach 1:
The patent implements a universal time series forecasting engine that can handle multiple domains and granularities through a single unified architecture. The system uses domain-agnostic diagnostic techniques and ensemble modeling that adapts to different time series characteristics without requiring domain-specific configuration, thereby achieving both high accuracy and broad adaptability.
Solution Approach 2:
The system dynamically adjusts modeling parameters and diagnostic thresholds based on the characteristics of input time series data. By automatically detecting pattern types (trend, seasonality, randomness) and adapting model parameters accordingly, the engine achieves high accuracy across different domains without manual configuration for each domain.
2Measurement precision
If complex forecasting models are deployed to handle various patterns, then forecasting accuracy is improved, but device complexity and computation time increase
Solution Approach 1:
The patent segments the forecasting process into distinct modular components: diagnostic phase (detecting trend, seasonality, randomness), model selection phase (choosing from ensemble of models), and forecasting phase (generating predictions). This segmentation allows the system to manage complexity systematically by handling each phase independently and selecting only necessary models based on detected patterns.
Solution Approach 2:
The system employs an ensemble of multiple forecasting models rather than relying on a single complex model. By maintaining a partial set of diverse models (statistical, machine learning, deep learning) and selecting only those relevant to the detected time series characteristics, the system achieves high accuracy while controlling overall complexity through selective model application.
3Measurement precision
If manual configuration of forecasting methods is performed, then domain-specific optimization is improved, but ease of operation and time required for deployment deteriorates
Solution Approach 1:
The forecasting engine performs self-configuration by automatically detecting time series characteristics and selecting appropriate models without user intervention. The diagnostic techniques automatically analyze data patterns, and the system autonomously chooses from the ensemble of models, eliminating the need for manual configuration while maintaining high accuracy through adaptive model selection.
Solution Approach 2:
The system performs preliminary diagnostic analysis automatically before model selection to understand time series characteristics. By pre-computing diagnostic metrics and pattern detection in advance, the system prepares all necessary information for optimal model selection without requiring user configuration, thereby improving ease of operation while maintaining accuracy.
4Measurement precision
If traditional forecasting approaches are used at production scale, then domain expertise is leveraged, but productivity and data storage requirements increase
Solution Approach 1:
The patent replaces manual domain expertise and traditional mechanical forecasting approaches with automated machine learning and deep learning algorithms. The system automatically learns patterns from data using neural networks and statistical models, eliminating the need for manual domain configuration while maintaining or improving accuracy and significantly enhancing processing efficiency at production scale.
