Things to remember

  • Why use big data?
    • Simple learning methods with large data sets can outperform complex learners with smaller datasets
    • The ordering of learning methods, best-to-worst, can be different for small datasets than from large datasets
    • The best way to improve performance for a learning system is often to collect more data
    • Large datasets often imply large classifiers
  • Asymptotic analysis
    • It measures number of operations as function of problem size
    • Different operations (eg disk seeking, scanning, memory access) can have very very different costs
    • Disk access is cheapest when you scan sequentially
