Active Learning - Exploration / Exploitation Score
Legacy Example - before KNIME AP 4.1 (Dec. 2019)Before KNIME 4.1 the Active Learning extension had these nodes which did not support interactive JavaScript views for KNIME WebPortal. This example in particular uses "Active Learn Loop End" whichenables the user to label the instances. Current Example - since KNIME AP 4.1 (Dec. 2019)With KNIME Analytics Platform 4.1 the Active Learning extension was updated to support interactive JavaScript views for KNIME WebPortal. In this example you can interactively label the instances usingKNIME WebPortal, which comes with KNIME Server. To test the workflow until the second iteration dothe following: 1) Right click Labeling View >"Execute and OpenViews"2) Label the instance using the in-view buttons3) Save new labels by clicking "Apply" and "Close"in the View lower left corner4) Right Click the Active Learning Loop End node>"Step Loop Execution" twice5) Open the Labeling View again.To apply interactions after the first iteration youneed the KNIME WebPortal, where the workflow ishidden and the user can access the view as aremotely accessible web-based application with"Next" and "Back" buttons. Active Learning - Exploration vs Exploitation Strategy: These workflows showexamples of Active Learning applications using the exploration vs exploitation strategy. The Legacy nodes enable you to run the ActiveLearning application from KNIME AnalyticsPlatform without KNIME Server. 1) Execute Active Learning Loop End2) Right click and select "View : View"3) Type in A or B, "Add Class" and "Continue"4) Either label until the last row or select"Terminate"This workflow cannot be deployed on KNIMEWebPortal via KNIME Server.
