  4. Keywords for Video Left to Middle: Middle to Right:

  5. Derivative Filters in 1 Minute Signal * Gt

  6. Keywords for Video Left to Middle: Middle to Right: Histogram

  7. Keywords for Video

  8. Co-occurance Matrix

  9. CP • Why not clustering on C? • Intuition Behind

  10. Embedding • Embedding • Given some points, define weights between any two points. • Given a plane, for each point, find a place to place it. • So that, in the plane, a pair of points has higher weights are closer.

  11. Embedding

  12. Co-embedding (See EigenMap): • Nodes: all prototypes and video segments • Weight between each node: • W(Prototype, node) • W(Prototype, Prototype)

  13. W(Prototype, Prototype)

  14. K-Means • Inter-Cluster Similarity • Unusual cluster has small Inter-Cluster Similarity

  15. Questions & Ideas • Thank you………………………………..
