  2. 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.

  3. Multiple Images in Single Request

    Allow predictions for multiple images (files) in a single request similar to what is supported for training.

    i.e. predictionEndpoint.PredictImages(Guid predictionKey, List<Stream> imageStreams)

  4. Export & Models or Download photos trained

    Due to single user limitation, would like to export & import models to other account. Or, wish if photo used for training be downloadable at once so to transplant model easily.

  5. Ignore tags with less than 5 images when training

    Currently, if you want to train your project, all tags need to have at least 5 images otherwise an error will be thrown and your entire project will not get trained.

    Please allow an option to ignore tags with less that 5 images when training

  7. API to bulk upload training image with tag

    API to bulk upload training image with tag will be more convenient in a situation where lot of images required for training.

  8. Increase Max image size (prediction)

    Most cameras and smart phones will produce pictures bigger than the Max image size (prediction) in the Vision Service API. Could it be increased or create a simple way to send a rescaled image to the Vision service API.

  9. Training - Allow us to crop or set bounds box for each tag

    I'd like the option to upload a single picture and tag it into multiple tags but tell the computer where in the picture to focus on what tag. This could help us get object level tagging if we wanted to take the time to train it.

  10. Provide managed .DLL for offline classification

    It would be very helpful to be able to download the compact model as a managed .DLL that has a single .Classify method. This way we could integrate the real time model into any application.

    Maybe add GPU option and/or multicore.

  11. 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."

  12. Select All on Predictions view

    I would like to be able to Select All images on the current page so that I can then use the "Tag Images" button.

    Currently, I have to click on each individual checkbox to select them all.

  13. Eliminate false positives

    I have trained my model with 500 images of different BMW motor vehicles however if i give it an image of a stretch Hummer it categorizes that as a BMW.

    It is able to correctly return low probability (or zero) for clearly non car related imagery but i would have thought it should also return a low probability of a stretch Hummer being a BMW too, not 99%

    Put another way, if an image is of the same type as that which the model is trained for then unless you have sufficient tags (e.g, lots of different vehicle makes) then…

  14. Allow tagged areas to be downloaded as images

    Would be great if we could download the image inside the bounding box, or perform OCR etc on the box.

  15. Training data analysis for improvement

    After training, it would be nice if we could see analysis on biases of train data set (e.g. a set of data tagged to "A" seems similar than other tags, or seem to have enough deviation in dataset, etc), so tthat we could add new data to correct those.

  16. Export to ONNX 2

    The 17763 release of Windows and WinML api's aren't compatible with current ONNX exports. Please update to avoid this error:

    Type Error: Type (map(string,tensor(float))) of output arg (loss) of node (ZipMap) does not match expected type (seq(map(string,tensor(float))))

  18. Export model

    When do you plan to give us access to the model? Export model: Tensor flow, CNTK seems not available right now.

  19. Give more information about prefered image size

    I have experimented with original and resized images to train classifiers and got strange results.

    When I used the "General" domain, the performance scores were better for original size images (5Mpixel).
    When I trained "General (Compact)" the performance score were better for resized (1Mpixel - width/height: 768*1024px) images.

    Can you give more infomation about what size do you use as input to train your models? Can the image resize algorythm cause the difference between performance of the same model?

  20. 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?
