Amazon AWS Certified AI Practitioner Sample Questions (Q259-Q264):NEW QUESTION # 259
A company is training ML models on datasets. The datasets contain some classes that have more examples than other classes. The company wants to measure how well the model balances detecting and labeling the classes.
Which metric should the company use?
  • A. Recall
  • B. Precision
  • C. Accuracy
  • D. F1 score
Answer: D
Explanation:
The correct answer is D - F1 score, which is the harmonic mean of precision and recall. AWS documentation states that the F1 score is the preferred metric when evaluating ML models trained on imbalanced datasets, where one class appears significantly more often than others. Accuracy becomes misleading in these situations because a model can achieve high accuracy simply by predicting the majority class. Precision alone measures correctness of positive predictions, while recall measures completeness-neither fully captures class balancing performance. The F1 score provides a combined measurement that reflects how well the model identifies minority classes while avoiding excessive false positives. AWS's ML Specialty Guide recommends using F1 for classification tasks where "class distribution is uneven or where both false negatives and false positives matter." This metric provides a fairer assessment of overall model performance across all class categories.

* AWS Certified Machine Learning Specialty Guide - Metrics for Imbalanced Classes
* Amazon SageMaker Developer Guide - Evaluating Classification Models

NEW QUESTION # 260
A company wants to develop ML applications to improve business operations and efficiency.
Select the correct ML paradigm from the following list for each use case. Each ML paradigm should be selected one or more times. (Select FOUR.)
* Supervised learning
* Unsupervised learning

Answer:
Explanation:

Explanation:

The company is developing ML applications for various use cases, and the task is to select the correct ML paradigm (supervised or unsupervised learning) for each. Supervised learning involves training a model on labeled data to make predictions, while unsupervised learning identifies patterns or structures in unlabeled data. Each use case aligns with one of these paradigms based on its requirements.
Exact Extract from AWS AI Documents:
From the AWS AI Practitioner Learning Path:
"Supervised learning uses labeled data to train models for tasks like classification (e.g., binary or multi-class classification), where the model predicts a category. Unsupervised learning works with unlabeled data for tasks like clustering (e.g., K-means clustering) or dimensionality reduction, identifying patternsor reducing data complexity without predefined labels." (Source: AWS AI Practitioner Learning Path, Module on Machine Learning Strategies) Detailed Explanation:
* Binary classification: Supervised learningBinary classification involves predicting one of two classes (e.g., yes/no, spam/not spam) using labeled data, making it a supervised learning task. The model learns from examples where the correct class is provided.
* Multi-class classification: Supervised learningMulti-class classification extends binary classification to predict one of multiple classes (e.g., categorizing items into several groups). Like binary classification, it requires labeled data, so it falls under supervised learning.
* K-means clustering: Unsupervised learningK-means clustering groups data into clusters based on similarity, without requiring labeled data. This is a classic unsupervised learning task, as the algorithm identifies patterns in the data on its own.
* Dimensionality reduction: Unsupervised learningDimensionality reduction (e.g., using techniques like PCA) reduces the number of features in a dataset while preserving important information. It does not require labeled data, making it an unsupervised learning task.
Hotspot Selection Analysis:
The hotspot lists four use cases, each with a dropdown containing "Select...," "Supervised learning," and
"Unsupervised learning." The correct selections are:
* Binary classification: Supervised learning
* Multi-class classification: Supervised learning
* K-means clustering: Unsupervised learning
* Dimensionality reduction: Unsupervised learning
Each paradigm (supervised and unsupervised learning) is used twice, as the question allows for paradigms to be selected one or more times.

NEW QUESTION # 261
A company has developed an ML model for image classification. The company wants to deploy the model to production so that a web application can use the model.
The company needs to implement a solution to host the model and serve predictions without managing any of the underlying infrastructure.
Which solution will meet these requirements?
  • A. Use Amazon SageMaker Serverless Inference to deploy the model.
  • B. Use Amazon API Gateway to host the model and serve predictions.
  • C. Use AWS Batch to host the model and serve predictions.
  • D. Use Amazon CloudFront to deploy the model.
Answer: A

NEW QUESTION # 262
An education provider is building a question and answer application that uses a generative AI model to explain complex concepts. The education provider wants to automatically change the style of the model response depending on who is asking the question. The education provider will give the model the age range of the user who has asked the question.
Which solution meets these requirements with the LEAST implementation effort?
  • A. Summarize the response text depending on the age of the user so that younger users receive shorter responses.
  • B. Fine-tune the model by using additional training data that is representative of the various age ranges that the application will support.
  • C. Use chain-of-thought reasoning to deduce the correct style and complexity for a response suitable for that user.
  • D. Add a role description to the prompt context that instructs the model of the age range that the response should target.
Answer: D

NEW QUESTION # 263
A company uses Amazon SageMaker AI to generate article summaries in multiple languages. The company needs a metric to evaluate the quality of the summary translations in multiple languages. Which evaluation metric will meet these requirements?
  • A. Bilingual evaluation understudy (BLEU)
  • B. Precision
  • C. Recall-Oriented Understudy for Gisting Evaluation (ROUGE)
  • D. Area Under the ROC Curve (AUC)
Answer: A
Explanation:
Comprehensive and Detailed
BLEU (Bilingual Evaluation Understudy) is the standard metric for evaluating machine translation quality across multiple languages.
ROUGE is for summarization quality (not translation).
AUC is for classification model performance.
Precision is a general metric but not specific for evaluating translations.
Reference:
AWS Documentation - Evaluation Metrics for NLP
