Release Notes

• v0.2.6a1 (Sept 1, 2021)

  • Adds support for creating features using python source code (assuming an existing parent source).
  • Users can provide a python function that will transform a source and create a new set of features using the results of that function

• v0.2.5 (Aug 18, 2021)

  • adds handling and user notification for highly null dataframes which would otherwise not function well with evaluate.profile or evaluate.feature_importance

• v0.2.4 (Aug 4, 2021)

  • supports tables named as restricted Snowflake keywords (e.g. ACCOUNT, CASE, ORDER) to be registered as Rasgo Sources

• v0.2.3 (July 30, 2021)

  • introduces publish.features_from_source_code() function. This function allows users to pass a custom SQL string to create a view in Snowflake using their own code. This function will: register a child source based off the parent source provided as input, register features from the new child source table.
  • introduces new workflow to publish.source_data() function. Pass in source_type="sql", sql_definition="<valid sql select string>" to create a new Rasgo DataSource as a view in Snowflake using custom SQL.
  • makes the features parameter optional in publish.features_from_source() function. If param is not passed, all columns in the underlying table that are not in the dimensions list will be registered as features
  • adds trigger_stats parameter to all publish method. When set to False, statistical profiling will not run for the data objects being published. Default = True
  • adds verbose parameter to all publish methods. When set to True, prints status messages to stdout to update users on progress of the function. Default = False.
  • introduces .sourceCode property on Rasgo DataSource and FeatureSet classes to display the SQL or python source code used to build the underlying table
  • introduces .render_sql_definition() method on Collection class to display the SQL used to create the underlying collection view
  • introduces .dimensions property on Rasgo Collection class to display all unique dimension columns in a Collection
  • introduces trigger_stats parameter in collection.generate_training_data() method to allow users to generate a sql view without kicking off correlation and join stats. Set to False to suppress stats jobs. Default=True.
  • Add support for optional catboost parameter train_dir in evaluate.feature_importance() function, which allows users to dictate where temporary training files are generated

• v0.2.2(July 14, 2021)

  • Allow for consistency in evaluate.feature_importance() evaluation metrics for unchanged dataframes
  • Allow users to control certain CatBoost parameters when running evaluate.feature_importance()

• v0.2.1(July 01, 2021)

  • expand evaluate.feature_importance() to support calculating importance for collections

• v0.2.0(June 24, 2021)

  • introduce publish.experiment() method to fast track dataframes to Rasgo objects
  • fix register bug

• v0.1.14(June 17, 2021)

  • improve new user signup experience in register() method
  • fix dataframe bug when experiment wasn't set

• v0.1.13(June 16, 2021)

  • intelligently run Regressor or Classifier model in evaluate.feature_importance()
  • improve model performance statistics in evaluate.feature_importance(): include AUC, Logloss, precision, recall for classification

• v0.1.12(June 11, 2021)

  • support fqtn in publish.source_data(table) parameter
  • trim timestamps in dataframe profiles to second grain

• v0.1.11(June 9, 2021)

  • hotfix for unexpected histogram output

• v0.1.10(June 8, 2021)

  • pin pyarrow dependency to < version 4.0 to prevent segmentation fault errors

• v0.1.9(June 8, 2021)

  • improve model performance in evaluate.feature_importance() by adding test set to catboost eval

• v0.1.8(June 7, 2021)

  • evaluate.train_test_split() function supports non-timeseries dataframes
  • evaluate.feature_importance() function now runs on an 80% training set
  • adds timeseries_index parameter to evaluate.feature_importance() & prune.features() functions

• v0.1.7(June 2, 2021)

  • expands dataframe series type recognition for profiling

• v0.1.6(June 2, 2021)

  • cleans up dataframe profiles to enhance stats and visualization for non-numeric data

• v0.1.5(June 2, 2021)

  • introduces pip install "pyrasgo[df]" option which will install: shap, catboost, & scikit-learn

• v0.1.4(June 2, 2021)
