Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems face challenges in optimizing process controls due to multiple interacting factors, long latency, and high variability, making it difficult to intuitively or singly optimize process controls.
Innovation Solution
The system automates the design and execution of randomized experiments to optimize planting and cultivation parameters, using machine learning to analyze outcomes and adjust parameters based on local field characteristics, user preferences, and jurisdictional requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current systems attempt to cope with multi-factorial problems, then they can address multiple interacting factors, but they become vulnerable to extrapolation error and are resource intensive
Solution Approach 1:
The system segments the field into multiple portions or zones, each with its own set of planting parameters. This segmentation allows the system to handle multi-factorial problems locally rather than globally, reducing extrapolation errors by making predictions based on localized data patterns rather than forcing a single model across heterogeneous conditions.
2Adaptability or versatility
If current systems attempt to cope with multi-factorial problems, then they can address multiple interacting factors, but they become resource intensive
Solution Approach 1:
By dividing the field into segments and training separate machine learning models for each segment, the system distributes computational resources across multiple smaller, specialized models rather than requiring one large, resource-intensive model to handle all factors across the entire field.
Solution Approach 2:
The system applies local quality by training segment-specific models that are optimized for local conditions. Each model learns from and adapts to the specific characteristics of its segment, improving adaptability to local multi-factorial interactions while reducing the computational burden compared to a global model.
3Quantity of substance
If randomized experiments are conducted across the entire field, then comprehensive data is collected, but local field characteristics are not adequately accounted for
Solution Approach 1:
The system segments the field into multiple portions and conducts randomized experiments within each segment. This approach collects comprehensive data across the entire field while simultaneously capturing local characteristics, as each segment's data is analyzed separately to identify location-specific patterns and relationships.
Solution Approach 2:
The system applies local quality by training segment-specific machine learning models that are optimized for local conditions. Each model learns from and adapts to the specific characteristics of its segment, improving adaptability to local multi-factorial interactions while reducing the computational burden compared to a global model.

AI summary
Systems and methods automate the design and execution of randomized experiments. Portions of a field are planted using an agricultural vehicle configured to randomly vary planting parameters when planting a portion of the field. A resulting crop outcome across each portion or sub-portion of the field is observed. A training set of data is generated that includes the varied planting parameters and the associated crop outcomes for each portion of the field. A machine-learned model is trained using the training set of data and is configured to predict a crop outcome for a portion of the field based on historical and forecast conditions and a set of planting parameters applied to a portion of the field. For subsequent iterations, for a target portion of the field, the machine-learned model can be applied to identify a set of planting parameters for planting the target portion of the field to optimize a desired crop outcome.
