  2. Recurrent Neural Networks (RNNs)

  3. Long Short-Term Memory (LSTM) networks

  4. Generative Adversarial Networks (GANs)


Correct Option: A
Explanation:

Convolutional Neural Networks (CNNs) are specifically designed for processing data that has a grid-like structure, such as images, and have become the dominant architecture for computer vision tasks due to their exceptional performance.

Which technique is commonly used to train machine learning models for computer vision tasks?

  1. Supervised learning

  2. Unsupervised learning

  3. Reinforcement learning

  4. Transfer learning


Correct Option: A
Explanation:

Supervised learning is widely used in machine learning computer vision, where labeled data is provided to the model during training, allowing it to learn the relationship between input images and their corresponding labels.

What is the process of dividing an image into smaller regions called superpixels?

  1. Segmentation

  2. Clustering

  3. Edge detection

  4. Feature extraction


Correct Option: A
Explanation:

Segmentation is the process of dividing an image into smaller regions, called superpixels, which are homogeneous in terms of color, texture, or other visual characteristics.

Which of these is a common application of machine learning computer vision in the medical field?

  1. Medical image analysis

  2. Drug discovery

  3. Clinical decision support systems

  4. Patient monitoring


Correct Option: A
Explanation:

What is the term for the ability of a machine learning model to perform well on unseen data that it has not been explicitly trained on?

  1. Generalization

  2. Overfitting

  3. Underfitting

  4. Regularization


Correct Option: A
Explanation:

Generalization refers to the ability of a machine learning model to perform well on unseen data that it has not been explicitly trained on, indicating its capacity to learn generalizable patterns from the training data.

Which of these is a popular dataset used for training and evaluating machine learning models for object detection tasks?

  1. ImageNet

  2. CIFAR-10

  3. MNIST

  4. PASCAL VOC


Correct Option: D
Explanation:

PASCAL VOC (PASCAL Visual Object Classes) is a widely used dataset for object detection and image classification tasks in computer vision, consisting of images with annotations for various object categories.

What is the term for the process of fine-tuning a pre-trained machine learning model on a new dataset?

  1. Transfer learning

  2. Domain adaptation

  3. Active learning

  4. Meta-learning


Correct Option: A
Explanation:

Transfer learning involves taking a pre-trained model that has been trained on a large dataset and fine-tuning it on a new dataset with a different task, leveraging the knowledge learned from the pre-trained model.

Which of these is a technique used to improve the performance of machine learning models by reducing overfitting?

  1. Dropout

  2. Data augmentation

  3. Early stopping

  4. L1 and L2 regularization


Correct Option: A
Explanation:

Dropout is a technique used in neural networks to prevent overfitting by randomly dropping out some neurons during training, encouraging the network to learn more robust and generalizable features.

What is the primary goal of image classification in machine learning computer vision?

  1. To assign labels to images based on their content.

  2. To detect and localize objects within images.

  3. To generate new images from scratch.

  4. To estimate the depth of objects in an image.


Correct Option: A
Explanation:

Image classification aims to assign labels to images based on their content, allowing computers to recognize and categorize objects, scenes, or activities within images.

Which of these is a common metric used to evaluate the performance of machine learning models for image classification tasks?

  1. Accuracy

  2. Precision

  3. Recall

  4. F1 score


Correct Option: A
Explanation:

Accuracy is a widely used metric for evaluating the performance of machine learning models for image classification tasks, measuring the proportion of correctly classified images out of the total number of images.

What is the term for the process of estimating the depth of objects in an image?

  1. Depth estimation

  2. Stereo vision

  3. Structure from motion

  4. Photogrammetry


Correct Option: A
Explanation:
