問題 #21
Which THREE types of data are used for Data Labeling?

A. Audio
B. Images
C. Graphs
D. Text Document

答案：B,D

解題說明：
Detailed Answer in Step-by-Step Solution:
* Objective: Identify three data types for OCI Data Labeling (question likely incomplete-assuming B, C, D, E options).
* Understand Data Labeling: Annotates data for ML-focuses on specific types.
* Evaluate Options (Assuming Typical Set):
* A: Audio-Not supported-incorrect.
* B: Text Document-Supported (e.g., NER)-correct.
* C: Images-Supported (e.g., object detection)-correct.
* D: Graphs-Not a standard type-incorrect.
* Assumed E: Videos-Supported but missing-adjust to fit.
* Reasoning: OCI supports text, images, and videos-question lists only four, so B and C are definite.
* Conclusion: B, C (third likely video, missing).
OCI documentation states: "Data Labeling supports text documents (B), images (C), and videos for annotation-audio (A) and graphs (D) are not included." Question likely meant three from a larger set; B and C are confirmed per OCI's Data Labeling capabilities.
Oracle Cloud Infrastructure Data Labeling Documentation, "Supported Data Types".

問題 #22
As a data scientist, you are working on a global health dataset that has data from more than 50 countries. You want to encode three features, such as 'countries', 'race', and 'body organ' as categories. Which option would you use to encode the categorical feature?

A. auto_transform()
B. show_in_notebook()
C. DataFrameLabelEncode()
D. OneHotEncoder()

答案：D

解題說明：
Detailed Answer in Step-by-Step Solution:
* Objective: Encode categorical features in a Data Science context (likely ADS SDK).
* Understand Encoding: Converts categories (e.g., countries) to numerical forms.
* Evaluate Options:
* A: Not a standard ADS method-incorrect.
* B: General transformation, not specific encoding-incorrect.
* C: OneHotEncoder-Standard for categorical encoding-correct.
* D: Visualization, not encoding-incorrect.
* Reasoning: One-hot encoding creates binary columns-ideal for multiple categories.
* Conclusion: C is correct.
OCI documentation states: "In ADS SDK, use OneHotEncoder (C) from sklearn (or similar) to encode categorical features like 'countries' into binary vectors for modeling." A isn't real, B is too broad, D is unrelated-only C fits OCI's encoding practice.
Oracle Cloud Infrastructure Data Science Documentation, "Feature Encoding with ADS".

問題 #23
True or false? Data scientists typically need a combination of technical skills, nontechnical ones, and suitable personality traits to be successful.

A. False
B. True

答案：B

解題說明：
Detailed Answer in Step-by-Step Solution:
* Objective: Assess required skills for data scientists.
* Analyze Skills:
* Technical: Coding, stats, ML.
* Nontechnical: Communication, business acumen.
* Traits: Curiosity, problem-solving.
* Reasoning: Success requires this mix-e.g., explaining models to stakeholders.
* Conclusion: A (True) is correct.
OCI documentation states: "Effective data scientists combine technical skills (e.g., Python), nontechnical skills (e.g., storytelling), and traits like analytical thinking." This holistic requirement is true (A), not false (B).
Oracle Cloud Infrastructure Data Science Documentation, "Data Scientist Skills".

問題 #24
Which statement accurately describes an aspect of machine learning models?

A. Model performance degrades over time due to changes in data.
B. Data models are more static and generally require fewer updates than software code.
C. Static predictions become increasingly accurate over time.
D. A high-quality model will not need to be retrained as new information is received.

答案：A

解題說明：
Detailed Answer in Step-by-Step Solution:
* Objective: Find a true statement about ML models.
* Evaluate Options:
* A: True-Data drift (changes in data distribution) degrades performance over time.
* B: False-Static predictions don't improve without retraining.
* C: False-Models need updates as data changes, unlike static software.
* D: False-Even high-quality models require retraining with new data.
* Reasoning: A reflects the reality of data drift, a common ML challenge.
* Conclusion: A is correct.
OCI documentation notes: "Model performance can degrade over time due to data drift, where the underlying data distribution changes, necessitating monitoring and retraining." B, C, and D contradict this-static predictions don't improve (B), models aren't static (C), and retraining is needed (D). A is the accurate aspect.
Oracle Cloud Infrastructure Data Science Documentation, "Model Monitoring and Drift".

問題 #25
As a data scientist, you require a pipeline to train ML models. When can a pipeline run be initiated?

A. Pipeline can be initiated after the active state.
B. Pipeline can be initiated before the active state.
C. Pipeline can be initiated during the pipeline run state.
D. Pipeline can be initiated once it is created.

答案：D

解題說明：
Detailed Answer in Step-by-Step Solution:
* Objective: Determine when an OCI Data Science pipeline can start.
* Understand Pipelines: They're workflows with defined steps, executed on demand or scheduled.
* Evaluate Options:
* A: Once created, a pipeline can be run immediately-correct.
* B: "During run state" implies it's already running-illogical.
* C: "After active state" is unclear; pipelines run when triggered, not post-state.
* D: "Before active state" is vague-creation precedes running.
* Reasoning: Pipelines are executable post-creation via UI/CLI-simplest interpretation is A.
* Conclusion: A is correct.
OCI Data Science documentation states: "After a pipeline is created, you can initiate a pipeline run immediately or schedule it using the OCI Console, CLI, or SDK." B, C, and D misalign with this-running starts post-creation (A), not during/after ambiguous states.
Oracle Cloud Infrastructure Data Science Documentation, "Pipelines - Running a Pipeline".
