Image Classification

Out of the Box Packages > UiPath Image Analysis > Image Classification

This preview model is a retrainable deep learning model used to classify images. You can train it on your own data and create an ML Skill to perform image classification. This ML Package must be retrained, if deployed without training first, deployment will fail with an error stating that the model is not trained.

This model is not available for offline installations.

Model details

Input type

FILE

Input description

Full path of the image file on which you want to classify.

Make sure that the image format is either JPEG or PNG.

Output description

JSON with identified label for the image and confidence score (between 0-1).

{
  "response": {
    "label": "car",
    "confidence": 0.85657345056533813
  }
}

Recommend GPU

By default, a GPU is recommended.

Training enabled

By default, training is enabled.

Pipelines

All three types of pipelines (Full Training, Training, and Evaluation) are supported by this package. For most use cases, no parameters need to be specified, the model is using advanced techniques to find a performant model. In subsequent trainings after the first, the model uses incremental learning (that is, the previously trained version will be used, at the end of a Training Run).

Dataset format

For training and evaluation datasets, point to a folder with a subfolder called images and this subfolder can contain input several folders with different classes (for example, a folder called cats with pictures of cats, and another one called dogs with pictures of dogs, and so on).

Example :

-- <Training / Evaluation Directory>
   -- images
      -- Bus
         -- bus001.jpg
         -- bus002.jpg
         -- bus003.jpg
      -- Truck
         -- truck001.jpg
         -- truck012.png
         -- truck0030.jpeg
      -- Car
