  1. Heat Map to describe what object impact to prediction

    Heat Map is very helpful to understand what area is impacted to Object Detetion task.
    Hope we can see it at Active Learning phase via REST API call.

  2. Ability to import iterations into the workspace to allow models to be generated on subsets of data

    I'd like to be able to Import the training data from an iteration into the workspace, modify that data and train a new iteration.

    This would allow multiple iterations to be trained with subsets of the same data. ie, you could have iterations containing data for Asia-Pacific, The Americas, and Global, all using a subset of the same training data. You can then import one of these iterations into your workspace to update the training images and create a new iteration for that locale, or import the global iteration to have access to the full set of training images.

  8. Multi user access to projects

    Just migrated from a Limited Trial to Azure resources. Would like to allow other users access to the project via the Custom Vision portal so they can add new images from predictions and train new iterations, but don't want them to be able to play with other settings via the Azure Portal for example. The Documentation doesn't mention multi user access as far as I can see.

  9. Better error information

    I'm currently struggling with an issue where my project is failing to train. Sadly, there is absolutely no useful information about WHY it's failing in either via the API or the UI.

    In the API I simply get a status of "Failed" for the iteration and in the UI I get "This iteration failed to train."

  10. Provide C# tensorflow example

    The Custom Vision documentation provides a nice example for how to use the tensorflow compact model in python, but no example for C#. Can you provide?

  12. Prediction API: Is there an example with base64 encoded image?

    I have tried the Prediction API with image (Content-Type: application/octet-stream) and URL (Content-Type: application/json) and these work great! I am looking for an example where I can use a base64 encoded string representation of the image with the prediction api.

  13. Additional Documentation - Object Detection Model Export

    Hello,

    Could you please provide detailed documentation regarding the integration of an exported model to CoreML. Currently, the model registers an output of a multi-dimensional array. Can the output be more defined so that it is more clear when integrated into iOS.

  14. How can we create a negative tag using the API ?

    I see that we can change the type (negative or non-negative) using the UI interface but not with the API.

  15. change the Dockerfile to include the -u for logging

    The Dockerfile, when exporting a Linux Container, has the command:

    CMD python app.py

    this is buffering the output of the app.py command, so you do not see the logged items as needed.

    If you change this to:

    CMD python -u app.py

    It will not buffer the output.

  16. Ability to give each image a name.

    Ability to give each image a name via the UI. Display that name when hovering over the image in the UI rather that displaying "open image detail". I have a lot of similar looking images and I want to name them by the date they were taken but I don't want the date to be a tag.

    You also need a category of UI on your suggestions box.

    Thanks for the suggestion. Just a couple of days ago we added a category for UI suggestion.

  17. Provide feature to changes subscription mapped with project

    Provide feature to changes subscription mapped with project.

    If we moved azure custom vision resources in azure portal then it exiting project not visible in portal.

    This is blocker need to fix. Project seems not working if subscription limit reached. Need to provide feature to change subscription mapping ASAP.

    Thanks, Great Api. Microsoft.
    Good Job.

  19. Display the endpoint in the Custom AI portal

    The SDK has been recently updated, and now the TrainingApi(trainingkey) class has been replaced by the CustomVisionTrainingClient(trainingkey, endpoint=endpoint) class.
    The only way to find the endpoint in the portal is to create a project.
    That doesn't help if you want to create the project programmatically using the SDK. Here's the code you would need to write:
    from azure.cognitiveservices.vision.customvision.training import CustomVisionTrainingClient

    trainer = CustomVisionTrainingClient(TRAINING_KEY, endpoint=ENDPOINT)

    Create a new project

    print ("Creating project...")
    project = trainer.create_project("My Project")

    However, I can't determine the ENDPOINT unless I've already created the project using the UI.
    At present, the Custom Vision preview only appears…

  20. tags

    Allow a tag to have a description ie a paragraph that describes what the tag is. This is different to the name, which is the only way currently to record info about the tag. The CustomVision.ai service should allow maintenance of the description and the API should pull back the description along with the name and score when accessing the predictions API.
