Community learn blocks
Building a robust machine learning model, especially in the realm of computer vision, is challenging due to the need for extensive datasets and significant computational resources. Transfer learning has emerged as a powerful solution, allowing developers to leverage pre-trained models and adapt them to their specific needs. This guide provides an overview of various community created custom learn blocks, and their applications.
Prerequisites
A object detection project: See object detection for details on how to create one.

Selecting a community Learn Block
To select a community created learning block, click Object detection in the menu on the left. Here you can select Choose a different model, and we will select YOLOv5 which was created by our COMMUNITY. You can see the detail for the given block here too for example: Yolov5 is a transfer learning model based on Ultralytics YOLOv5 using yolov5n.pt weights, supports RGB input at any resolution (square images only).

Key Considerations
Hardware Compatibility
Ensure that your chosen learn block is compatible with your hardware. Some blocks, like YOLOv5, have specific hardware requirements.
Limitations and Challenges
Each learn block comes with its own set of limitations. Understanding these is crucial for effective model development.
Use Cases
Align your project requirements with the capabilities of the learn block. For instance, use YOLOv5 for complex object detection tasks and Keras for simpler tasks.
Troubleshooting and Known Issues
The community blocks are not always integrated by Edge Impulse. This means they won't be tested on our CI/CD workflows.
Thus, we will provide limited support on the forum. If you are interested in using them for an enterprise project, please check our pricing page and contact us directly, our solution engineers can work with you on the integration:
YOLOv5 (Community Block)
Log items.
Metrics output issues.
Jetson Nano compatibility issues.
Lack of model size feedback pre-training completion.
Fixed batch size, no modification option.
EfficientNet (Community Block)
Potential compatibility issues with low-resource devices.
Scikit-learn (Community Block)
Potential compatibility issues with low-resource devices.
Conclusion
Custom learn blocks offer a flexible approach to machine learning, enabling you to tailor models to your specific needs. By understanding the capabilities and limitations of each block, you can harness the power of machine learning more effectively in your projects.
