Missing Domain Information Knime
Put data science into production in the enterprise with knime server.
Missing domain information knime. This can improve performance. The default value is set to the number of processors or cores that are available to knime. To do this a data scientist creates a knime workflow that extracts terms and properties from a certain ontology and applies this knowledge to different tasks ranging from domain exploration to data integration.
If set to 1 the algorithm is performed sequentially. This node is useful when the domain information of the data has changed and must be updated in the table specification for instance the domain information as contained in a table spec may be void when a row filtering e g. Skip nominal columns without domain information if checked nominal columns containing no domain value information are skipped.
Resorts and or inserts interactively possible values to the domain of a certain column of the input table. Scans the data and updates the possible values list and or the min and max values of selected columns. The free and open source visual workflow builder.
Domain calculator 4 parameter optimization loop. Outlier removal is carried out. A histogram that should show an empty bin for a value that is not actually present in the data.
Also the sorting on the domain values can be changed. Learns a random forest which consists of a chosen number of decision trees. Scans the data and updates the possible values list and or the min and max values of selected columns.
To use this node in knime install knime ensemble learning wrappers from the following. Each of the decision tree models is learned on a different set of rows records and a different set of columns describing attributes whereby the latter can also be a bit vector or byte vector descriptor e g. The reading and processing of ontologies can be automated with knime analytics platform.
