1Measurement precision
If machine learning models are manually configured for embedded devices, then accuracy can be optimized, but the configuration process becomes time-consuming and complex
Solution Approach 1:
The system enables automatic configuration of machine learning models on embedded devices through self-service mechanisms. The configuration service automatically determines optimal model parameters, hyperparameters, and deployment settings without requiring manual intervention, thus reducing configuration time while maintaining accuracy optimization.

If complex machine learning models are deployed on embedded devices, then accuracy improves, but device resource consumption increases
Solution Approach 1:
The configuration service automatically adjusts model parameters, architecture complexity, and resource allocation based on the embedded device's specific constraints and performance characteristics. This enables the system to find the optimal balance between accuracy and energy consumption by dynamically changing model parameters rather than using fixed complex models.
Solution Approach 2:
The system employs dynamic configuration that adapts model complexity and resource usage based on real-time device conditions and performance requirements. This dynamic approach allows the model to operate at optimal accuracy levels while consuming minimal energy, resolving the static contradiction between model complexity and resource consumption.

AI summary
A system may configure a sensing system implemented by an embedded device. The system may configure a sensing system to generate an image from a point cloud including data points in three dimensions. The data points may be associated with at least three values. The image may be generated by mapping first and second values of data points to first and second coordinates of pixels of the image and third values of data points to intensities of the pixels. The system may configure a sensing system to invoke a machine learning model to process the image. The machine learning model may be trained for image processing. In some implementations, the mapping may include quantizing the first and second values into ranges of the first and second coordinates and quantizing the third values into a range of the intensities.
