v0.4.0

Breaking Changes ⚠️

• The dataset interface has changed significantly. Refer to the documentation for upgrading:
• The interface for models' .train() method has changed. train now accepts either a Dataset or an iterable for training, where instances are objects with x and y properties for input and output, respectively.
• BatchPrediction.predict() now accepts datasets or iterables.
• data stores now take a location as argument rather than a configuration object

Many components and methods have been renamed for consistency. Any application built with a previous version of Marcelle is expected to break. The online documentation is up to date with the current naming. The list of name changes is as follows:

Previous name	New Name
Module	Component
ModuleBase	ViewContainer
Dashboard.start()	Dashboard.show()
Dashboard.destroy()	Dashboard.hide()
DashboardPage.useLeft()	DashboardPage.sidebar()
Wizard.start()	Wizard.show()
Wizard.destroy()	Wizard.hide()
Wizard.step()	Wizard.page()
Button.$down	Button.$pressed
textfield	textField
chart	genericChart
sketchpad	sketchPad
mlp	mlpClassifier
knn	knnClassifier
onnx	onnxModel
tfGenericModel	tfjsModel
mobilenet	mobileNet
parameters	modelParameters
classificationPlot	confidencePlot
visObjectDetection	detectionBoxes

New Features

• Lazy iterables have been added to process service data, in particular dataset data (TODO: add link to documentation)
• Services now support a $distinct query parameter to get the list of distinct values for a particular field.
• K-Means clustering
• Styling no longer pollutes global CSS. Tailwind's Preflight was removed so that Marcelle does not interact with top-level styles when integrated in another application.

Internal Changes

• The core UI components have been updated
• Storybook has been added to support the development of core UI components
• The performance of KNN and DatasetBrowser has been improved
• [style] ESLint configuration has been improved
• [style] For-of loops are used instead of forEach
