Interactive Pattern Discovery with Mirage A fundamental concern in data analysis is to find correlations among different things. Mirage uses exploratory visualization, intuitive graphical operations to help • Track horizontal correlations across different types of attributes for the same objects or events • Track vertical correlations across layers of abstraction from signals to the results of analysis • Integrate human and machine pattern recognition capabilities Lucent Technologies - Proprietary
Vertical Correlations across Layers of Analysis Processed Images Raw Images Numerical Features Classes and Groups Validation in Input Domain Relationship between Groups Interpretation in Context Lucent Technologies - Proprietary
Horizontal Correlations: Similarity of Objects from Different Perspectives • Objects can be described by many types of attributes: position, morphology, color, spectra, temporal variability, motion parameters … • Meaningful similarity metric exists only for attributes of the same type • Similar groups found from one perspective need to be correlated to those from others e.g. Are the objects similar in color also similar in shape? Shape groups Color groups Lucent Technologies - Proprietary
