Questions and Answers

Why do data-related tasks take so much time and effort in typical machine learning projects?

  • Machine learning projects do not require extensive data-related tasks
  • Many tasks like data identification, aggregation, cleaning, labelling, and augmentation are specific to problem domains and require custom solutions (correct)
  • Data-related tasks involve simple and straightforward processes
  • Most tasks rely on automated processes which are time-consuming

What does the 'Velocity' aspect of the 4V's of Big Data refer to?

  • There is a lot of data to store, requiring a lot of storage
  • Data is of uncertain or dubious quality, requiring systems to cope with data uncertainty
  • Data comes in many different formats and forms
  • Data comes in at high rates and speeds, requiring the ability to ingest data at high rates (correct)

What is the main challenge posed by the 'Variety' aspect of Big Data?

  • There is a lot of data to store, requiring a lot of storage
  • Data comes in at high rates and speeds
  • Data is of uncertain or dubious quality
  • Data comes in many different formats and forms, requiring systems to be flexible (correct)

Briefly summarize the 4V's of Big Data.

<p>Volume: Refers to the size of data and the need for a lot of storage. Velocity: Involves the high rate at which data comes in and the need to ingest data at high rates. Variety: Refers to data coming in many formats and the need for system flexibility. Veracity: Involves uncertain or dubious quality of data and the need to measure and cope with data uncertainty.</p> Signup and view all the answers
