Train Using AutoDL (GeoAI)

Available with Image Analyst license.

Summary

Trains a deep learning model by building training pipelines and automating much of the training process. This includes data augmentation, model selection, hyperparameter tuning, and batch size deduction. Its outputs include performance metrics of the best model on the training data, as well as the trained deep learning model package (.dlpk file) that can be used as input for the Extract Features Using AI Models tool to predict on new imagery.

Usage

• You must install the proper deep learning framework for Python in ArcGIS Pro.

  Learn how to install deep learning frameworks for ArcGIS

• If you will be training models in a disconnected environment, see Additional Installation for Disconnected Environment for more information.

• The time it takes the tool to produce the trained model depends on the following:

  • The amount of data provided during training
  • The AutoDL Mode parameter value
  • The Total Time Limit (Hours) parameter value

  By default, the timer for all modes is set at 2 hours. The Basic mode will train the selected networks on the default backbone within the given time. The Advanced mode will divide the total time by two, perform the model evaluation in the first half, and determine the top two performing models for evaluating on other backbones in the second half. If the amount of data being trained is large, all the selected models may not be evaluated within 2 hours. In such cases, the best performing model determined within 2 hours will be considered the optimum model. You can then either use this model or rerun the tool with a higher Total Time Limit (Hours) parameter value.

• This tool can also be used to fine-tune an existing trained model. For example, an existing model that has been trained for cars can be fine-tuned to train a model that identifies trucks.

• To run this tool, a GPU-equipped machine is required. If you have more than one GPU, use the GPU ID environment.

• The input training data for this tool must include the images and labels folders that are generated from the Export Training Data For Deep Learning tool.

• Potential use cases for the tool include training object detection and pixel classification models for extracting features such as building footprint, pools, solar panels, land cover classification, and so on.

• For information about requirements for running this tool and issues you may encounter, see Deep Learning frequently asked questions.
