Clustering Question: what if we don’t have (or don’t know) labels for data: Transcript
Function approximation does not work Fx xgty x feature vector y label but we dont know y yet Patterns may still exist depending on the relationship between records What is clustering. All you have to do is burn flip and burn It combines the LightScribe enabled DVD drive of your PC with specially coated CD or DVD discs sold separately and enhanced disclabeling software A LightScribeenabled DVD disc drive uses an optical laser in t Outline. Validating clustering results. Randomization tests. Cluster Validity . All clustering algorithms provided with a set of points output a clustering. How . to evaluate the “goodness” of the resulting clusters?. Beth . Benas. Rizwan. . Habib. Alexander . Lowitt. Piyush. . Malve. Contents. What is Gene Clustering?. Two or more genes that code for the same or similar products. Two different processes for duplication of original genes via: . Lecture outline. Distance/Similarity between data objects.
