It is well known throughout the data science  community that data preparation, pre-processing, and feature engineering  are one of the most cumbersome parts of the data science workload. So as we continue to innovate here at with our end-to-end automated machine learning (autoML ) capabilities, we challenged ourselves to evolve the process of feature engineering into more robust feature transformation .

The H2O AI Cloud  enables exploratory data analysis capabilities through automated visualizations and insights. This core functionality allows data scientists to see feature information, interactions, charts and plots to rapidly understand the dataset they are working with. This accelerates the discovery process for data scientists in finding signal driving features and interactions hidden in their data. The H2O AI Cloud enables these dynamic interactions and feature transformations to be extracted automatically, while simultaneously giving users the ability to turn anything off or on at their choosing, enabling full control of the evolutionary algorithm driving data intelligence.’s proprietary evolutionary algorithm, which is used to quantitatively experiment and test hundreds of combinations and feature transformations to find signals in the noise is running underneath the surface of’s autoML . Some of the robust automatic feature engineering capabilities include:

Numeric Transformers:  Interactions, Binning, Clustering, Target Encoding, Weight of Evidence, Truncated SVD, DBSCAN, TNSE, UMAP

Time Series:  Date & DateTime, Exponentially Weighted Moving Averages, Lags, Interactions, and Aggregations

Categorical:  One Hot Encoding, Cross Validation Target Encoding & Numeric Encoding, Weight of Evidence

Text Transformers:  BERT , BiGRU, Text CNN, CharCNN, TFIDF

Time Transformers:  Dates (Days, Months, Years, Seconds etc), Holidays

Image Models and Transformers:  Image AutoML, Image Vectorizer

The H2O AI Cloud rapidly accelerates the speed at which data scientists and data engineers can analyze and prepare a dataset for modeling, enabling them to make models with more accuracy, speed and transparency.
