AutoML is upgraded to AutoML v1.0 and the changes include:

  • Switched to using Pandas Dataframes internally. AutoML now uses Pandas dataframes internally instead of Numpy dataframes, avoiding needless conversions.

  • Pytorch is now an optional dependency. If Pytorch is installed, AutoML automatically considers multilayer perceptrons in its search. If Pytorch is not found, deep learning models are ignored.

  • Updated the Pipeline interface to include train(), which runs all the pipeline stages though doesn’t do the final fitting of the model ( fit() api should be used if final fit is needed).

  • Updated the Pipeline interface to include refit() to allows you to refit the pipeline to an updated dataset without re-running the full pipeline again. We recommend this for advanced users only. For best results, we recommended that you rerun the full pipeline when the dataset changes.

  • AutoML now reports memory usage for each trial as a part of its trials attributes. This information relies on the maximum resident size metric reported by Linux, and can sometimes be unreliable.

  • holidays is now an optional dependency. If holidays is installed, AutoML automatically uses it to add holidays as a feature for engineering datetime columns.

  • Added support for Anomaly Detection and Forecasting tasks (experimental).

  • Downcast dataset to reduce pipeline training memory consumption.

  • Set numpy BLAS parallelism to 1 to avoid CPU over subscription.

  • Support for ONNX. AutoML models can now be serialized using ONNX by calling the to_onnx() API on the AutoML estimator.

  • Pre-processing has been overhauled to use sklearn pipelines to allow serialization using ONNX. Numerical, categorical, and text columns are supported for ONNX serialization. Datetime and time series columns are not supported.

  • Torch-based deep learning models, TorchMLPClassifier and TorchMLPRegressor, have been added.

  • GPU support for XGBoost and torch-based models have been added. This is disabled by default, and can be enabled by passing in ‘gpu_id’: ‘auto’ in engine_opts in the constructor. ONNX serialization for GPUs has not been tested.

  • Adaptive sampling’s learning curve has been smoothened. This allows adaptive sampling to converge faster on some datasets.

  • Improvements to ranking performance in feature selection were added. Feature selection is now much faster on large datasets.

  • You can manually specify a hyperparameter search space to AutoML. New parameter added to the pipeline. This allows you to freeze some hyperparmaters or to expose further ones for tuning.

  • New API: Refit an AutoML pipeline to another dataset. This is primarily used to handle updated training data, where you train the pipeline once, and refit in on newer data.

  • AutoML no longer closes a user specified Dask cluster.

  • AutoML properly cleans up any existing futures on the Dask cluster at the end of fit.


MLX is upgraded to MLX v1.0.16 the changes include:

  • MLX is now distributed in the General Machine Learning conda environments.

  • Updated the explanation descriptions to use a base64 representation of the static plots. This obviates the need for creating a mlx_static directory.

  • Replaced the boolean indexing in slicing Pandas dataFrame with integer indexing. After updating to Pandas >= 1.1.0 the boolean indexing caused some issues. Integer indexing addresses these issues.

  • Fixed MLX related import warnings.

  • Corrected an issue with ALE when the target values are strings.

  • Removed the dependency on Paramiko.

  • Addresses issue with ALE when the target values are not of type list.

AutoML upgraded to 0.4.2 the changes include:

  • Reduced parallelization on low compute hardware.

  • Support for passing in a custom logger object in automl.init(logger=).

  • Support for datetime columns. AutoML should automatically infer datetime columns based on the Pandas dataframe, and perform feature engineering on them. This can also be forced by using the col_types argument in The supported types are: ['categorical', 'numerical', 'datetime']


MLX upgraded to MLX 1.0.7 the changes include:

  • Updated the feature distributions in the PDP/ICE plots (performance improvement).

  • All distributions are now shown as PMFs. Categorical features show the category frequency and continuous features are computed using a NumPy histogram (with ‘auto’). They are also separate sub-plots, which are interactive.

  • Classification PDP: The y-axis for continous features are now auto-scaled (not fixed to 0-1).

  • 1-feature PDP/ICE: The x-axis for continuous features now shows the entire feature distribution, whereas the plot may show a subset depending on the partial_range parameter (for example, partial_range=[0.2, 0.8] computes the PDP between the 20th and 80th percentile. The plot now shows the full distribution on the x-axis, but the line charts are only drawn between the specified percentile ranges).

  • 2-feature PDP: The plot x and y axes are now auto-set to match the partial_range specified by the user. This ensures that the heatmap fills the entire plot by default. However, the entire feature distribution can be viewed by zooming out or clicking Autoscale in plotly.

  • Support for plotting scatter plots using WebGL (show_in_notebook(..., use_webgl=True)) was added.

  • The side-issues that were causing the MLX Visualization Omitted warnings in JupyterLab was fixed.

April 30 2020

Environment Updates

  • The home folder is now backed by block volume. You can now save all your files to the /home/datascience folder, and they persist when you deactivate and activate your sessions. The block_storage folder no longer exists. The Oracle Cloud Infrastructure keys can be saved directly to the ~/.oci folder, and no symbolic links are required.

Note: The ads-examples folder in the home folder is a symbolic link to the /opt/notebooks/ads-examples folder. Any changes made in ads-examples aren’t saved if you deactivate a notebook.

  • Each new notebook that is launched has a prepopulated accordion style cell containing useful tips.

March 18 2020

Access to ADW performance has been improved significantly

Major improvements made to the performance of the ADW dataset loader. Your data is now loaded much faster, depending on your environment.

Change to with ADW with format='sql' no longer requires the index_col to be specified. This was confusing, since “index” means something very different in databases. Additionally, the table parameter may now be either a table or a sql expression.

ds =
  format = 'sql',
  table = """
    SELECT *
    FROM sh.times
    WHERE rownum <= 30

No longer automatically starts an H2O cluster

ADS no longer instantiates an H2O cluster on behalf of the user. Instead you need to import h2o on your own and then start your own cluster.

Preloaded Jupyter extensions

JupyterLab now supports these extensions:

  • Bokeh

  • Plotly

  • Vega

  • GeoJSON


  • Variable Inspector

  • VDOM

Profiling Dask APIs

With support for Bokeh extension, you can now profile Dask operations and visualize profiler output. For more details, see Dask ResourceProfiler.

You can use the ads.common.analyzer.resource_analyze decorator to visualize the CPU and memory utilization of operations.

During execution, it records the following information for each timestep:

  • Time in seconds since the epoch

  • Memory usage in MB

  • % CPU usage


from ads.common.analyzer import resource_analyze
from ads.dataset.dataset_browser import DatasetBrowser
def fetch_data():
    sklearn = DatasetBrowser.sklearn()
    wine_ds ='wine').set_target("target")
    return wine_ds

The output shows two lines, one for total CPU percentage used by all the workers, and one for total memory used.

Dask Upgrade

Dask is updated to version 2.10.1 with support for Oracle Cloud Infrastructure Object Storage. The 2.10.1 version provides better performance over the older version.
