- [Model Training](/extensible-modules/advanced-development-and-application-of-ai-vision-modules/model-training.md): With deep learning networks can learn data features from large amounts of data, which can be applied to a variety of detection, segmentation tasks.
- [Model quantification](/extensible-modules/advanced-development-and-application-of-ai-vision-modules/model-quantification.md): In the ‘Model Training’ section, we explained how to train a yolov8 model, but in order to deploy it on Grove Vision V2, we need to further quantify the model. This section is described below:
- [Model deployment](/extensible-modules/advanced-development-and-application-of-ai-vision-modules/model-deployment.md): In this section, we will learn how to upload the model to the hardware and complete communication with the Petoi robot dog.
- [Training on the COCO DIY dataset](/extensible-modules/advanced-development-and-application-of-ai-vision-modules/training-on-the-coco-diy-dataset.md): This section describes how to extract some of the labels and data from the COCO dataset for training using the scripting tool provided by Petoi.
