Data Mining Exploratory Data Analysis Measuring Data Similarity and Dissimilarity Data Matrix and Dissimilarity Matrix Proximity Measures for Nominal Attributes Proximity Measures for Binary Attributes Dissimilarity of Numeric Data: Minkowski Distance Proximity Measures for Ordinal Attributes Dissimilarity for Attributes of Mixed Types Cosine Similarity 41
Data Mining Exploratory Data Analysis Measuring Data Similarity and Dissimilarity 42 A cluster is a collection of data objects such that the objects within a cluster are similar to one another and dissimilar to the objects in other clusters. Outlier analysis also employs clustering-based techniques to identify potential outliers as objects that are highly dissimilar to others.

Data Mining Exploratory Data Analysis Similarity, Dissimilarity, and Proximity 43 Similarity measure or similarity function A real-valued function that quantifies the similarity between two objects Measure how two data objects are alike: The higher value, the more alike Often falls in the range [0,1]: 0: no similarity; 1: completely similar Dissimilarity (or distance ) measure Numerical measure of how different two data objects are In some sense, the inverse of similarity: The lower, the more alike Minimum dissimilarity is often 0 (i.e., completely similar) Range [0, 1] or [0, ∞) , depending on the definition Proximity usually refers to either similarity or dissimilarity
Data Mining Exploratory Data Analysis Data Matrix and Dissimilarity Matrix 44 Data matrix A data matrix of data points with dimensions Dissimilarity (distance) matrix data points, but registers only the distance d ( i, j ) (typically metric)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
