Explanation:
GNNs excel at capturing complex relationships and dependencies in graph data, which traditional neural networks cannot handle effectively. This is due to their ability to model interactions between nodes in an arbitrary graph structure.

Question No : 2

Which evaluation metric is best suited for regression tasks where the model's prediction errors should be evaluated on a scale proportional to the variance of the data?

A.Mean Squared Error (MSE)
B.Root Mean Squared Error (RMSE)
C.R-squared (Coefficient of Determination)
D.Mean Absolute Error (MAE)

정답:
Explanation:
R-squared (Coefficient of Determination) is well-suited for regression tasks as it measures the proportion of variance in the dependent variable that is predictable from the independent variables. It provides insight into how well the model captures the variance in the data relative to a simple mean-based model.

Question No : 3

Which method tests the statistical significance of regression coefficients?

A.AIC criterion
B.F-test analysis
C.BIC criterion
D.t-test analysis

정답:
Explanation:
The t-test assesses the statistical significance of individual regression coefficients in a linear model. It tests whether the coefficients are significantly different from zero, helping to identify which predictors are meaningful.

Question No : 4

How can the inclusion of context in a prompt influence a large language model's responses?

A.It makes the model more computationally efficient
B.It narrows down the model's output options
C.It introduces bias into the model's learning process
D.It reduces the overall training time required

정답:
Explanation:
Including context in a prompt narrows down the model's output options by providing additional information that guides the model towards more relevant and specific responses. This helps in producing outputs that are more aligned with the intended task or Question.

Question No : 5

What is a typical characteristic of an edge AI device?

A.Low latency and real-time data processing capabilities
B.Dependence on continuous cloud connectivity for operation
C.High computational power and extensive storage capacity
D.Limited ability to handle complex algorithms and models

정답:
Explanation:
A typical characteristic of an edge AI device is its low latency and real-time data processing capabilities. These features enable quick decision-making and immediate responses to data inputs directly on the device.

Question No : 6

What is the primary advantage of using a deep Convolutional Neural Network (CNN) over a shallow CNN for complex image recognition tasks?

A.Reduced need for data augmentation
B.Better ability to learn hierarchical features
C.Higher dimensionality of feature maps
D.Faster training time

정답:
Explanation:
Deep CNNs have more layers, allowing them to learn hierarchical features from raw images. This enables the network to capture more complex patterns and representations, leading to better performance on complex image recognition tasks.

Question No : 7

Which method is most effective for reducing model bias related to underrepresented groups in the training data?

A.Re-weighting the training samples
B.Reducing the learning rate
C.Increasing the model's depth
D.Using a higher batch size

정답:
Explanation:
Re-weighting the training samples is an effective method for addressing model bias, particularly for underrepresented groups. By assigning more weight to samples from these groups, the model can better learn to make fair predictions and reduce bias.

Question No : 8

Which leadership style is best suited for managing a rapidly changing AI project?

A.Servant leadership prioritizing team support and development
B.Laissez-faire leadership allowing flexibility
C.Autocratic leadership with rigid structures
D.Transactional leadership with a focus on short-term goals

정답:
Explanation:
Laissez-faire leadership, which allows for flexibility, is best suited for managing rapidly changing AI projects. This style supports adaptive decision-making and innovation by giving team members the autonomy to respond effectively to new challenges and changes.

Question No : 9

Which AWS service would be best for integrating a machine learning model with a workflow that involves data from various sources and requires complex orchestration?

A.AWS CodePipeline
B.AWS Glue
C.Amazon RDS
D.AWS Step Functions

정답:
Explanation:
AWS Step Functions is best for integrating machine learning models into workflows that involve data from various sources and require complex orchestration. It enables you to build and manage workflows with multiple steps, including data integration and model inference.

Question No : 10

Which leadership style is most effective for driving innovation in an AI engineering team?

A.Laissez-faire leadership with minimal oversight
B.Transactional leadership focusing on rewards and penalties
C.Democratic leadership encouraging team participation
D.Autocratic leadership with strict control

정답:
Explanation:
Democratic leadership, which encourages team participation, is most effective for driving innovation in an AI engineering team. This style fosters collaboration, idea sharing, and creativity, which are crucial for developing innovative solutions and staying ahead in technology.

Question No : 11

How should an AI project team handle conflicting priorities among stakeholders?

A.By deferring conflicting requests until the end of the project
B.By prioritizing the requests of the highest-ranking stakeholder
C.By making unilateral decisions without consulting stakeholders
D.By facilitating discussions to reach a consensus on priorities

정답:
Explanation:
Facilitating discussions to reach a consensus on priorities helps in managing conflicting priorities among stakeholders. This approach ensures that all perspectives are considered and that decisions align with the overall project goals and stakeholder needs.

Question No : 12

In big data systems, what is the primary advantage of using MapReduce?

A.Supports real-time analytics
B.Improves model interpretability
C.Enables parallel processing
D.Enhances fault tolerance

정답:
Explanation:
MapReduce is a programming model that facilitates the parallel processing of large data sets across distributed clusters, breaking down tasks into smaller, manageable parts that can be processed concurrently, thereby improving efficiency.

Question No : 13

Which practice is essential for successful cross-functional collaboration in AI projects?

A.Sharing relevant data and insights across teams
B.Focusing exclusively on team-specific objectives
C.Maintaining separate workflows for each team
D.Restricting access to project information to a few members

정답:
Explanation:
Sharing relevant data and insights across teams is essential for successful cross-functional collaboration. It ensures that all teams have the necessary information to make informed decisions and align their efforts towards common goals, enhancing overall project effectiveness.

Question No : 14

Which technique is used to prevent overfitting by randomly dropping neurons during training?

A.Early Stopping
B.Data Augmentation
C.L2 Regularization
D.Dropout

정답:
Explanation:
Dropout is a regularization technique that prevents overfitting by randomly dropping neurons during training. This forces the network to learn redundant representations and prevents any single neuron from becoming overly specialized, thereby improving generalization.

Question No : 15

What is the significance of the Nash Equilibrium in the context of GANs?

A.It represents the point where the generator's loss is minimized
B.It indicates the point where the generator and discriminator are in balance
C.It is the stage where the training process should be stopped
D.It occurs when the discriminator's accuracy reaches 100%

정답:
Explanation:
The Nash Equilibrium in GANs represents the point where the generator and discriminator are in balance. At this equilibrium, the generator produces realistic data samples that the discriminator cannot easily distinguish from real data, indicating that both networks are well-trained.
