Analyzing Error Sources to Direct Machine Learning Development Efforts
Question: According to the provided text, what are the two major sources of error in machine learning, and how does understanding them guide a machine learning practitioner's decision-making regarding project tactics like adding more training data?
Sample answer: The two major sources of error in machine learning are bias and variance. By understanding these two components, a machine learning practitioner can systematically evaluate whether implementing specific performance-improving tactics, such as collecting and adding more training data, represents an efficient and good use of development time.
Key points:
- Identify bias and variance as the two major sources of error.
- Explain that understanding bias and variance guides the choice of performance-improvement tactics.
- Mention that this understanding helps determine if adding more data is a good use of time.
Rubric: Answers must identify both bias and variance as the two major sources of error and explain that understanding them is crucial for deciding if tactics like adding data are a good use of time.
