2. Which of the following is a common objective function used in MTL?

Mean Squared Error (MSE)

Categorical Cross-Entropy

Kullback-Leibler Divergence (KL-Divergence)

All of the above

All of these objective functions can be used in MTL depending on the nature of the tasks and the specific problem.

Explanation

All of these objective functions can be used in MTL depending on the nature of the tasks and the specific problem.

3. What are some benefits of Multi-Task Learning?

Improved generalization performance

Efficient use of training data

Ability to transfer knowledge across tasks

All of the above

All of these benefits can be realized through MTL, as it allows sharing of information across related tasks, leading to better generalization and more efficient utilization of training data.

Explanation

All of these benefits can be realized through MTL, as it allows sharing of information across related tasks, leading to better generalization and more efficient utilization of training data.

4. What is task-relatedness in Multi-Task Learning?

The degree to which two tasks are correlated and share underlying features.

The complexity of individual tasks in relation to each other.

The number of tasks that can be solved using MTL.

The number of iterations required for convergence in MTL.

Task-relatedness refers to the degree of correlation between tasks and the extent to which they share underlying features. High task-relatedness is desirable in MTL as it allows for effective transfer of knowledge between tasks.

Explanation

5. Which of the following is NOT a challenge in Multi-Task Learning?

Negative Transfer

Increased model complexity

Difficulty in defining task-relatedness

Limited availability of labeled data

While defining task-relatedness can be a challenge, it is not considered one of the main challenges in MTL. The main challenges include negative transfer, increased model complexity, and limited availability of labeled data.

Explanation

6. What is the difference between Multi-Task Learning and Transfer Learning?

MTL solves multiple related tasks together, while Transfer Learning uses pre-trained models for a single task.

MTL can transfer knowledge across tasks, while Transfer Learning cannot.

MTL is primarily used in supervised learning, while Transfer Learning is used in unsupervised learning.

There is no difference, MTL and Transfer Learning are the same.

MTL involves solving multiple related tasks simultaneously, whereas Transfer Learning typically uses pre-trained models for a single task.

Explanation

MTL involves solving multiple related tasks simultaneously, whereas Transfer Learning typically uses pre-trained models for a single task.

7. What is the role of shared representations in Multi-Task Learning?

Shared representations are used to transfer knowledge between tasks.

Shared representations increase model complexity and hinder task performance.

Shared representations have no impact on the performance of individual tasks.

Shared representations are used to calculate task-relatedness.

Shared representations capture task-agnostic features and facilitate the transfer of knowledge between tasks, leading to improved performance on individual tasks.

Explanation

Shared representations capture task-agnostic features and facilitate the transfer of knowledge between tasks, leading to improved performance on individual tasks.

8. Which type of neural network architecture is commonly employed in Multi-Task Learning?

Multi-Layer Perceptron (MLP)

Convolutional Neural Network (CNN)

Recurrent Neural Network (RNN)

All of the above

All of these neural network architectures are commonly used in MTL, depending on the nature of the tasks and the input data.

Explanation

All of these neural network architectures are commonly used in MTL, depending on the nature of the tasks and the input data.

9. When is Multi-Task Learning preferred over single-task learning?

When tasks are strictly unrelated and have no shared features or dependencies.

When there is a limited amount of labeled training data available.

When the goal is to achieve the best possible performance on each individual task.

Multi-Task Learning is always preferred over single-task learning.

MTL is preferred over single-task learning when there is limited labeled training data available, as it can benefit from information sharing and improve generalization performance.

Explanation

MTL is preferred over single-task learning when there is limited labeled training data available, as it can benefit from information sharing and improve generalization performance.

10. Which field(s) commonly utilize Multi-Task Learning?
