![]() Group By: If the Method is either Mean or Mode, then choose the column or columns to group by.Ĭombine Method: If the Method is Median, then choose how to combine quantiles on even sample sizes. Mean replaces NAs with the column mean Median replaces NAs with the column median Mode replaces with the most common factor (for factor columns only). Method: The type of imputation to perform. The following options can be specified when imputing dataset:įrame: The dataset containing the column to impute Note that if a factor column is supplied, then the method must be Mode. These columns can be passed by index or by column name using the Group By option. Additionally, you can also perform imputation based on groupings of columns from within the dataset. The Impute option allows you to perform in-place imputation by filling missing values with aggregates computed on the “na.rm’d” vector. To impute data in a dataset, click the Data menu and select Impute. H2O Flow is designed to guide you every step of the way, by providing input prompts, interactive help, and example flows. You can even disable the input cells to run H2O Flow using only the GUI. You can click your way through any H2O operation without ever writing a single line of code. While H2O Flow supports REST API, R scripts, and CoffeeScript, no programming experience is required to run H2O Flow. When you execute the cell, the output is a graphical object, which can be inspected to view additional details. Each cell contains an input field that allows you to enter commands, define functions, call other functions, and access other cells or objects on the page. The cells can be modified, rearranged, or saved to a library. H2O Flow sends commands to H2O as a sequence of executable cells. It allows you to access any H2O object in the form of well-organized tabular data. However, rather than displaying output as plain text, Flow provides a point-and-click user interface for every H2O operation. Based on your models, you can make predictions and add rich text to create vignettes of your work - all within Flow’s browser-based environment.įlow’s hybrid user interface seamlessly blends command-line computing with a modern graphical user interface. ![]() H2O Flow allows you to use H2O interactively to import files, build models, and iteratively improve them. With H2O Flow, you can capture, rerun, annotate, present, and share your workflow. It is a web-based interactive environment that allows you to combine code execution, text, mathematics, plots, and rich media in a single document. H2O Flow is an open-source user interface for H2O.
