  2. 자료구조 시간 효율성 및 공간(메모리) 효율성을 높이기 위한 데이터의 구조는 ? 예) Big Data를 표현하기 위한 구조 Stack Graph Queue

  3. Data Structures • Efficient ways of storing and organizing data in a computer • provide a means to manage huge amounts of data efficiently • Ex) Big data: Web data, medical data, communication data, and whatever  Data Mining Laboratory

  4. Data Structures Efficient data structures Efficient algorithms Good quality software  Data Mining Laboratory

  5. Data Structures • Efficient ? • Space complexity • Time complexity  Data Mining Laboratory

  6. 강의 내용 주요 자료구조 • Arrays • Stacks • Queues • Linked List • Tree • Graph • Sorting • Hashing  Data Mining Laboratory

  7. Stacks • LIFO (Last-in First-out) • push/pop operations • Applications • Calculators • Backtracking • Solving maze problems  Data Mining Laboratory

  8. Queues • FIFO (First-In First-Out) • add/delete operations • Applications • service/job scheduling  Data Mining Laboratory

  9. Trees • Hierarchical tree structure with a set of linked nodes • binary trees • binary search trees • threaded binary trees • heap • selection trees  Data Mining Laboratory

  10. Graphs • A finite set of ordered pairs of edges and vertices • Applications • path finding • social network mining  Data Mining Laboratory

  11. Sorting • 종류 • Selection sorting • Insertion sorting • Bubble sorting • Quick sorting • Heap sorting • Merge sorting • Radix sorting • …  Data Mining Laboratory
