ITPEC IP October 2024 Question 94
ITPEC IP October 2024 — Question 94 of 100
Machine learning together with statistical analysis can be effective for forecasting unknown outcomes from big data. Statistical methods quantify relationships and uncertainty, while machine-learning models can learn complex patterns from large, diverse datasets and make predictions on unseen cases. The appropriate technique depends on data quality, purpose, validation, explainability, and operational constraints.
Answer (a)
Why not others:
- (b) images, video, and audio can be analyzed using computer vision, speech, and signal-processing methods
- (c) human behavior can also be studied from sensor, transaction, location, and other machine-generated data
- (d) originally unstructured content such as blogs can be analyzed when relevant and lawfully available
Key rule: Big-data analysis can use structured and unstructured data in many media; format or original purpose alone does not exclude data from analysis.
