==== Contents ====

The lecture Big Data Analytics develops competencies in performing data mining tasks on very large amounts of data that cannot be stored in main memory. The lecture provides the key ideas of similarity search using minhashing and locality-sensitive hashing, of data stream processing where data arrives so fast that it has to be processed immediately or is otherwise lost, of Web-related algorithms such as Google's PageRank, of algorithms for mining frequent itemsets, association rules and frequent subgraphs, of algorithms to analyze the structure of large graphs such as social network graphs, and of the map-reduce principle to design parallel algorithms.
  - Finding Similar Items
