Customizable Feature Selection
Added the ability to select which features you use in your model. This includes engineered features.To customize your feature selection, go to the Features tab in the Feature Engineering step. Reducing your feature count can speed up the modeling process.
Partial Dependence Plot Performance Improvements
Improved the speed of populating the Partial Dependence plot. On average, you can expect 50% faster load times.
December 8, 2022
Version 2022.41
Runtime Versioning
Added the ability to upgrade individual projects to the latest AYX ML Runtime Version—and to revert back to your most recent version if you change your mind. You can find this functionality in the 3-dot menu on each project on the project page.
Project versioning ensures that changes to modeling algorithms DO NOT impact business results unless you select an upgrade. This provides a consistent experience when you revisit a previous project.
Note that the AYX ML Runtime Version upgrade only applies to model tuning improvements made by Alteryx. Improvements to the UX, new features, security, and infrastructure update automatically.

Version 2022.40
Time Series Enhancements
What Is Time Series
Time Series regression expands your modeling capabilities with data that includes a time component. Now, you can forecast into the future and get accurate predictions. Do things like demand forecasting, financial forecasting, and more with Alteryx Machine Learning.
Alteryx Machine Learning uses commonly used and state-of-the-art time series models. These include Facebook Prophet, ARIMA, and ETS, in addition to other regression models such as XGBoost and LightGBM.
Why Time Series Matters
Use Time Series for future-looking, time-based predictions. This empowers you to quickly leverage prior data to forecast future outcomes. Enhanced capabilities account for trending and seasonality, making model performance stronger.
New Functionality
Time Series now includes 2 major enhancements to the Machine Learning experience:
Decomposition [Model Setup step]: Visualize trend and seasonal signals in isolation from the residual signal. This allows the non-time series specific models to perform better in most cases (where time-series specific models are Facebook Prophet, ARIMA, and ETS). We run all models with and without decomposition and then display the best model on the leaderboard. We support Decomposition Visualizations for these frequencies:
Hourly
Daily
Weekly
Monthly
Quarterly
Time Series Forecast Graph and Data Export [Export and Predict step]: Introduced line graph and graph data to visualize and then use forecasted data.
Changes to Existing Workflow
For a clearer workflow, we moved items from Data Insights to a new Model Setup step. Note that this doesn’t represent new functionality, just a new organizational flow.
August 25, 2022
Version 2022.28
Feature Engineering Step
Added an automated Feature Engineering step to Alteryx Machine Learning. This step allows you to apply primitives (generalized operations) to calculate new features. These features can improve model performance and help you gain further insight. Additionally, you can view the correlation values for the engineered features. Look for this new feature on the left side of the Alteryx Machine Learning interface.
August 2, 2022
Version 2022.25
Updated Integer Parsing
We extended support for parsing real numbers (for example, 2.45 and 3.0) as integers. The parsing truncates the right side of the decimal point. For example, 2.45 becomes 2, and 3.0 becomes 3.
New Time Series Primitives
Added "Fourier Transform" and "Rolling Trend" primitives for improved Time Series feature engineering. We also added an additional 16 DateTime primitives for feature engineering.
Custom Input for DateTime Formats
Added 20 new DateTime formats and the ability to enter your own custom format. You can now use more DateTime datasets with our Time Series Regression model.
Machine Learning Predict Tool—Data Validation for Time Series Models
Added Time Series data validation to the Machine Learning Predict tool in Designer. The data validation checks if your input data length is longer than the forecast horizon.
Correlation Tab—Switch X-Y Axes on 2-Variable Plot
Added an option to switch the axes of the 2-Variable Plot in the Correlations tab.
July 21, 2022
Version 2022.24
Pipeline Highlights
Expanded Pipeline Highlights in the Auto Model leaderboard for categorical and numerical operations. We now sort operations by order of execution in the model pipeline. Use this information to choose a model based on which operations we use in the model.
June 23, 2022
Version 2022.20
Time Series—Irregularly Spaced Data
Support added for irregularly spaced Time Series datasets.
Time Series—Data Checks
Added data checks to warn you when we modify your data.
June 16, 2022
Version 2022.19
Stop Criteria—Model Setup
You now have the option to set "time" as the stop criteria for model search completion. The minimum stop time is 1 minute.
April 18, 2022
Version 2022.12
Facebook® Prophet Estimator
Added Prophet to improve predictions for Time Series Regression models. This addition targets datasets with trends and seasonality.
ARIMA Regressor
Added ARIMA Regressor for Time Series Regression. ARIMA is a high performant statistical algorithm for Time Series datasets.
Select Completed Models
Updated the Stop button in the Auto Model search step. You can now stop the model search and select completed models up to that point.
Features Visibility
Updated the Features panel in the Auto Model step to show all features contributing to your model. This helps you understand and evaluate models based on the features in use. In addition, features used in ensemble models are also shown.
March 17, 2022
Version 2022.08
Unary Column Detection
A new data check identifies unary data type columns and automatically recommends next steps. This enables you to quickly detect columns to exclude from Machine Learning. The No Variance Data Check flags columns that contain only 1 unique value and then provides you with a recommendation to drop those columns.
