Iterative refinement of cohorts using visual exploration and data analytics
View Patent ↗Methods and apparatus are provided for iterative refinement of cohorts using visual exploration and data analytics. A cohort comprised of multiple data objects is defined by obtaining an initial cohort seeding; visualizing the initial cohort using a selected view to present a current cohort; reducing the current cohort using one or more visual filters; visualizing the current cohort using a selected view; expanding the current cohort using one or more selected analytics; and determining whether the current cohort should be further modified using one or more of additional reductions and additional expansions. Cohorts can be passed between views and analytics via drag-and-drop interactions as an analysis unfolds.
1. An apparatus defining a cohort comprised of multiple data objects, the apparatus comprising:
a memory; and
at least one hardware device, coupled to the memory, operative to:
obtain an initial cohort seeding;
visualize said initial cohort using a selected view to present a current cohort;
reduce said current cohort using one or more visual filters;
visualize said current cohort using a selected view;
expand said current cohort using one or more selected analytics using computational techniques to automatically identify additional objects for said current cohort based on one or more similarity input parameters obtained from a user, wherein said current cohort is expanded by a specified expansion factor to add additional objects to said current cohort that satisfy a similarity metric with respect to one or more existing objects in said current cohort, wherein said step of expanding said current cohort using one or more selected analytics further comprises the step of modifying said current cohort to produce a larger cohort by expanding one or more of the number of said objects in said cohort and the number of properties for the objects in said cohort; and
determine whether said current cohort should be further modified using one or more of additional reductions and additional expansions.
2. The apparatus of claim 1 , wherein said initial cohort seeding is obtained from one or more of a user query, system analytics and a previously generated cohort.
3. The apparatus of claim 1 , wherein said at least one hardware device is further configured to select a view by dragging and dropping said current cohort onto a visual representation for the selected view.
4. The apparatus of claim 1 , wherein said at least one hardware device is further configured to process a visualization-driven query to gather data required for the selected view.
5. The apparatus of claim 1 , wherein current cohort is reduced by interacting with a selected visualization to reduce a number of said data objects in said current cohort.
6. The apparatus of claim 5 , wherein said interaction with said visualization for reducing said current cohort further comprises a direct visual selection of graphical elements that represent subsets of said current cohort and applying filters based on the visual selection.
7. The apparatus of claim 1 , wherein said current cohort is expanded by dragging and dropping said current cohort onto a visual representation for a given analysis to initiate said step of expanding said current cohort using one or more selected analytics.
8. The apparatus of claim 1 , wherein said current cohort is expanded by modifying said current cohort to produce a larger cohort by expanding one or more of the number of said objects in said cohort and the number of properties for the objects in said cohort.
9. The apparatus of claim 1 , wherein said at least one hardware device is further configured to visualize said expanded current cohort using the current selected view.
10. The apparatus of claim 1 , wherein said determination is based on one or more of a statistical measure and experience of a user.
