Deep Learning 面接の質問と回答
質問 6. What is transfer learning, and how is it used in deep learning?
Transfer learning involves using a pre-trained model on one task as the starting point for a different but related task. It leverages the knowledge gained from the source task to improve the learning of the target task, especially when data for the target task is limited.
質問 7. Explain the concept of dropout in neural networks and its purpose.
Dropout is a regularization technique where randomly selected neurons are ignored during training. It helps prevent overfitting by ensuring that no single neuron becomes overly dependent on specific features, promoting a more robust network.
質問 8. What is a convolutional neural network (CNN), and how is it different from a fully connected neural network?
A CNN is a type of neural network designed for processing grid-like data, such as images. It uses convolutional layers to automatically and adaptively learn hierarchical features. Unlike fully connected networks, CNNs preserve spatial relationships within the input data.
質問 9. What is the role of the learning rate in training a neural network?
The learning rate determines the size of the steps taken during optimization. A higher learning rate may speed up convergence, but it risks overshooting the minimum. A lower learning rate ensures stability but may slow down convergence. It is a crucial hyperparameter in training neural networks.
質問 10. Explain the concept of batch normalization and its advantages in training deep neural networks.
Batch normalization normalizes the inputs of a layer within a mini-batch, reducing internal covariate shift. It stabilizes and accelerates the training process, enables the use of higher learning rates, and acts as a form of regularization, reducing the reliance on techniques like dropout.
