Version History of Machine Learning Playground

4.1

November 19, 2022

The app has been recompiled to run under iOS v16.1. The app layout was updated so that it displays properly across newer as well as older iPad generations.

4.0

August 13, 2020

1) Added a new chart to show the accuracy of your models plotted against the epochs 2) Removed the numeric output loss data 3) Moved the descriptions of the built-in models to a dedicated page 4) Changed the output activation function of the Boston House Price dataset to Rectified Linear Unit 5) Fixed a bug that caused a duplicate entry in the model picker control when a custom dataset was edited

3.3

March 30, 2020

Recompiled to iOS v3.4.

3.2

November 13, 2019

1) Fixed a bug related to renaming an existing custom dataset after making changes. The new file name did not immediately appear in the My Datasets list or in the list of datasets in the home view. 2) Added some defensive coding when selecting a dataset in the home view. The app now checks for consistency between the number of inputs and outputs and the data itself. If there is a mismatch an error dialog is displayed and the model cannot be executed. This is an issue for custom datasets only.

3.1

October 23, 2019

Fixed some UI issues that popped up with iOS 13.

August 24, 2019

The plot of Loss vs Epochs now includes the loss data for the test dataset. Users can perform feature scaling on their custom datasets. Minor bug fixes.

2.0

August 12, 2019

You can now create your own datasets for modeling. A new page named "Custom Datasets" allows you to paste-in your comma-separated data and specify the number of inputs, hidden nodes and outputs. Also, you can specify the activation functions at the hidden and output layers. When you add or delete a custom dataset the dataset picker on the main page is updated to reflect those changes.

Description of Machine Learning Playground

Machine Learning Playground allows you to experiment with neural network models. The application ships with four read-only datasets. Some datasets are designed for regression analysis while others are suited for classification. The models themselves will consist of three layers: inputs, hidden and outputs. There is a set of hyper-parameters that you can adjust to gauge their effects on a model's accuracy. You can define a stopping condition for halting the model's training step via the number of epochs or the loss target value. You can also switch between two loss functions - Mean Squared Error and Cross-Entropy. Zoomable charts plot loss and accuracy across the epochs. The app will also allow you to create and save custom datasets. You specify the number of inputs, hidden nodes and outputs along with the activation functions at the hidden and output layers. Tune your model built on your custom dataset using the hyper-parameters. The data files that you create are stored in the app's domain on the iPad. Those files will persist until you either delete them yourself using the delete feature on the Custom Datasets page, or you remove the app entirely from your iPad.
