New Functionality

  • Labels are now shown as text during training, making it easier to see which class is which.

  • The Softmax component has been removed because of redundancy.

  • If you stop training and start it again, you will now see it continue from the previous statistics if you choose to start from the last checkpoint.

  • The error messages in the Data Wizard have now been improved to give a hint as to what may be wrong.

  • Random Partition now uses a fixed seed.

Bugs

Version 0.12.16 (July 20, 2021)

New Functionality

  • Preview generation in the workspace is now faster.

  • Pre-processing has been improved by pre-generating the samples rather than generating them on the fly.

Bugs

  • Backend requests have been cleaned up and should be more responsive in general.

  • Crashes for very small (1x1) previews will no longer occur.

Version 0.12.15 (July 14, 2021)

New Functionality

  • Improved recommendations for Categorical Decoders.

Bugs

  • The questionnaire is now visible when you first start the tool.

Version 0.12.14 (July 6, 2021)

New Functionality

  • Added three new datasets that will automatically download when you start the tool the first time: "Human Activity", "Wildfire" and "Covid19".

Bugs

  • All CSV filetypes should now be readable in the Data Wizard, whereas before some of them caused strange symbols to appear which caused an error.

Version 0.12.13 (July 1, 2021)

New Functionality

  • A new onboarding experience has been added.

  • We have now upgraded to using TensorFlow 2.5! Make sure to upgrade your CUDA to 11.2 and cuDNN to 8.1 to be able to use GPUs with this version.

Bugs

  • The Accuracy, Loss and other line charts are no longer empty before the second epoch starts.

  • Internal error messages relating to the Data Wizard and modelling are now properly logged.

  • You can no longer set height or width to 0 in the Reshape pre-processing in the Data Wizard.

Version 0.12.12 (June 30, 2021)

New Functionality

  • "Kernel Offline" should no longer happen, instead, error messages will be much more precise as to the cause of the issue.

  • The error messages in the workspace and the Data Wizard have been improved.

  • The numerical target statistics view (often what you use for regression) has now been improved.

  • The pre-processing UI has been updated.

Bugs

  • Onboarding will now be visible when you first enter the tool, rather than only appearing after selecting the ModelHub in the left menu.

  • The Binary data type has been temporarily disabled because Categorical is currently better in every way.

Version 0.12.11 (June 24, 2021)

Bug Fixes

  • Fixed a dependency issue in the frontend that was causing strange behaviours such as being unable to delete models, test popup not showing up, a project modal showing up, etc.

  • The resource section in the top right has been improved.

  • There is now a loading indicator after you choose to Customize or Run a model from the Data Wizard.

  • You can now access our community sites like YouTube, Forum, Slack and GitHub through the top-right icons.

  • In the Training Settings, you can now choose to automatically save the weights of your model every epoch, rather than just at the end of the training.

  • Notebook view has temporarily been removed as that currently is not up to date.

  • There is now a restriction on creating models with only a single Target column, until we implement better support for multi-modal problems.

  • A lot of unnecessary kernel calls have been removed.

  • Extensions of your loaded data are now case insensitive.

  • When refreshing the tool, you will now open the model you were viewing rather than the tool going through all of them.

Version 0.12.9 (June 16, 2021)

Note: this version has been removed due a critical error.

Version 0.12.8 (June 8, 2021)

New Functionality

  • Loading messages for tests have been improved so you can now see their progression.

  • The training statistics have now been updated for categorical targets during training; you can now see:

    • Predictions for each class summed over all samples in that epoch

Bug Fixes

  • It's now no longer possible to press the Open button in ModelHub without having any models selected to go to a bugged workspace.

Version 0.12.7 (June 4, 2021)

New Functionality

  • A few preprocessing options have been added: Random cropping. Random rotation.

  • The Data Wizard has been improved to make it more intuitive.

  • We have added a direct messenger to the tool, so you can easily get in contact with us. You can find it under the ? -> Send us a Message.

Bugs Fixes

  • The Kernel will no longer crash on certain learning rates.

  • Fixed a backwards compatibility issue with versions earlier than 0.12.4.

Version 0.12.6 (June 1, 2021)

New Functionality

  • There is now a loading message when running a test.

  • A few preprocessing options have been added:

    • Flipping images

    • Resizing images

  • Multiple columns now work inside the tool, although some manual work is still required to put the model together.

  • You can now pre-process your data inside the Data Wizard by pressing the little symbol on top of the column. The pre-processing available so far is Normalize for Image and Numerical data.

  • The data types in the Data Wizard are now filtered on what is possible for each column. For example, if a column contains a path then it can only be Image type (and later on Text).

Bug Fixes

  • The components in the map will no longer have eternal spinners if you start training straight from the Data Wizard.

New Functionality

  • The Create model UI has been updated to look a bit cleaner.

Bug Fixes

  • The dropdown on the components in the workspace now works.

  • Data settings can no longer be randomly copied over to another model (this used to cause the model to use the wrong input and target data).

Version 0.12.2 (May 7, 2021)

Bugs Fixes

  • Fixed progress bar during training; it now reaches 100% every time.

  • Pre-trained components now automatically use their preprocessing function to ensure that data input to them is correctly formatted.

Version 0.12.1 (May 7, 2021)

Note: this version has been removed due a critical error.

Version 0.12.0 (May 5, 2021)

New Functionality

  • The old Create Model popup together with the template has been removed. This means that models created pre-0.12 will no longer be usable after upgrading to 0.12.0.

  • A new featured called Data Wizard has been introduced. The Data Wizard provides a more structured way to load your data, making the models data centric. It works by:

    • allowing you to load a CSV file.

    • allowing you to define the CSV file (specifying which columns are the input and target, and their types).

    • providing you with a recommended model that can be run immediately.

  • There are currently four supported column types in the Data Wizard: Numerical, Categorical, Binary, and Image, allowing you to mix them to build models such as: Image Classification, Regression, Segmentation, simple Image Generation, Autoencoder, etc. Read more about the Data Wizard here. Note that this link will become available once we document this functionality.

  • Object Detection has been temporarily removed.

  • GAN has been temporarily removed.

  • Pre-trained models have been added as components under the Deep Learning, including VGG16, ResNet50, InceptionV3, and MobileNetV2.

  • Data components have been removed and replaced by Input and Target components.

  • Training components have been removed. The training engine is now running behind the scenes and has been generalized to work for all above mentioned cases.

  • The Statistics View has received a slight update, where it now shows statistics based on the Inputs and Targets rather than the Training components.

  • The Test View has been reworked. You can now run one (or many) tests on one (or many) of your models. The current tests available are: Confusion Matrix and Metrics Table.

Bug Fixes

  • Changing the model path will no longer cause saving checkpoints to crash in Windows.

  • Zooming by inputting a number will no longer cause the components placement to change.

  • The correct TensorFlow version (2.4.1) is now shown in the bottom right.
