Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional automated pitch classification systems are limited in their ability to accurately and rapidly classify pitches due to the use of only a limited amount of pitch information, and they lack real-time capabilities and error correction mechanisms.
Innovation Solution
A real-time automated pitch classification system that utilizes a computing device to receive and process pitch properties and pitcher information, including a repertoire of pitches, using a classification algorithm such as an artificial neural network to determine the type of pitch thrown, with additional inputs like weather and stadium information for enhanced accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional automated pitch classification systems use limited pitch information, then the system complexity is reduced, but the pitch classification accuracy deteriorates
Solution Approach 1:
The system segments pitch classification into multiple independent analysis components: pitch movement analysis, pitch speed analysis, pitch trajectory analysis, and pitcher repertoire analysis. Each component processes specific features independently and contributes to the final classification, allowing comprehensive analysis without overwhelming system complexity
Solution Approach 2:
The system adds temporal dimension by analyzing pitch movement over time frames (first time frame, second time frame, third time frame), transforming static pitch data into dynamic temporal sequences. This enables differentiation of pitch types based on their evolution patterns rather than just endpoint characteristics
2Measurement precision
If manual post-game analysis is used for pitch classification, then comprehensive pitch information can be analyzed, but real-time classification capability is lost
Solution Approach 1:
The system performs preliminary classification during the pitch delivery itself by analyzing movement patterns across multiple time frames as the pitch progresses. This real-time preliminary analysis enables immediate pitch type identification without requiring post-game review, maintaining both accuracy and timeliness
Solution Approach 2:
The system incorporates feedback mechanisms where classification results from preliminary analysis are continuously refined based on additional pitch data and pitcher repertoire information. This iterative feedback process ensures accurate classification while maintaining real-time operational capability
3Reliability
If a comprehensive classification algorithm considering multiple factors is implemented, then pitch classification reliability is improved, but the computational processing time increases
Solution Approach 1:
The classification algorithm is segmented into hierarchical processing stages: first analyzing dominant pitch movement patterns, then refining with speed and trajectory data, and finally confirming against pitcher repertoire. This segmented approach processes comprehensive data reliably while maintaining efficient throughput by handling analyses in manageable stages
Solution Approach 2:
The system performs partial classification based on available data at each moment, providing immediate results when data is sufficient and refining later when more data becomes available. This allows the system to maintain high productivity by classifying pitches with sufficient information while still achieving high reliability through iterative refinement
Data Source
AI summary
A method for performing pitch classification includes receiving, at a computing device, one or more pitch properties corresponding to a ball thrown by a pitcher. Pitcher information corresponding to the pitcher is also received. The pitcher information includes at least an identification of one or more pitches that are in a repertoire of the pitcher. A classification of the pitch is determined using at least a pitch classification algorithm, where the classification of the pitch is based at least in part on the one or more pitch properties and at least in part on the pitcher information.
