質問 # 83
Which of the following types of machine learning is a GPU most commonly used for?
正解:C
解説:
GPUs excel at the massive parallelism required for the matrix and tensor operations at the heart of deep neural network training and inference, making them the go-to hardware for deep learning workloads.
質問 # 84
A data analyst wants to use compression on an analyzed data set and send it to a new destination for further processing. Which of the following issues will most likely occur?
正解:C
解説:
Compression and decompression are CPU‐intensive operations; on large data sets, the extra processing load can significantly spike CPU utilization. Memory, OS support, or library dependencies are far less likely to be the primary bottleneck in a standard compression workflow.
質問 # 85
A data scientist has built an image recognition model that distinguishes cars from trucks. The data scientist now wants to measure the rate at which the model correctly identifies a car as a car versus when it misidentifies a truck as a car. Which of the following would best convey this information?
正解:A
解説:
A confusion matrix directly shows true positives (cars correctly identified) and false positives (trucks misidentified as cars), giving you exactly the rates you're interested in.
質問 # 86
Which of the following does k represent in the k-means model?
正解:B
解説:
# In k-means clustering, k represents the number of clusters that the algorithm will attempt to form. The algorithm partitions the dataset into k distinct, non-overlapping clusters based on feature similarity. Each cluster has a centroid, and the algorithm aims to minimize the intra-cluster variance.
Why the other options are incorrect:
* A: Number of tests is unrelated to the k-means algorithm.
* B: Data splits refer to cross-validation or train/test splits, not k in k-means.
* D: Distance between features is computed during clustering but is not what "k" represents.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 4.2:"In k-means clustering, k denotes the number of clusters into which the dataset will be partitioned."
* Introduction to Machine Learning, Chapter 6:"The 'k' in k-means specifies how many groupings the algorithm will seek to discover based on proximity in feature space."

質問 # 87
SIMULATION
A data scientist needs to determine whether product sales are impacted by other contributing factors. The client has provided the data scientist with sales and other variables in the data set.
The data scientist decides to test potential models that include other information.
INSTRUCTIONS
Part 1
Use the information provided in the table to select the appropriate regression model.
Part 2
Review the summary output and variable table to determine which variable is statistically significant.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.






正解:
解説:
Part 1
Linear regression.
Of the four models, linear regression has the highest R² (0.8), indicating it explains the greatest proportion of variance in sales.
Part 2
Var 4 - Net operations cost.
Net operations cost has a p-value of essentially 0 (far below 0.05), indicating it is the only additional predictor statistically significant in explaining sales. Neither inventory cost (p≈0.90) nor initial investment (p≈0.23) reach significance.
