1. Question

What is the primary purpose of Sequence-to-Sequence (Seq2Seq) models in deep learning?

Text classification

Correct Incorrect Correct answer

Text classification

Correct Incorrect Correct answer

Handling tasks that involve variable-length sequences, such as machine translation and text summarization

Correct Incorrect Correct answer

Reinforcement learning

Correct Incorrect Correct answer

2. Question

What is the key idea behind “attention mechanisms” in Seq2Seq models, and how do they improve performance

Attention mechanisms allow models to selectively focus on specific parts of the input sequence when generating the output sequence, improving alignment and handling longer sequences

Correct Incorrect Correct answer

Attention mechanisms enable models to ignore parts of the input sequence to improve efficiency and speed

Correct Incorrect Correct answer

Attention mechanisms increase the model's attention span by using recurrent connections

Correct Incorrect Correct answer

Attention mechanisms help Seq2Seq models generate random outputs for diversity

Correct Incorrect Correct answer

3. Question

What is the primary architectural limitation of traditional Seq2Seq models based on recurrent neural networks (RNNs)?

Inability to handle variable-length sequences

Correct Incorrect Correct answer

Lack of parallelism in training and inference

Correct Incorrect Correct answer

Excessive use of memory

Correct Incorrect Correct answer

Overfitting to training data

Correct Incorrect Correct answer

4. Question

In the context of machine translation, what role does the encoder in a Seq2Seq model play?

Translates the source sentence to the target language directly

Correct Incorrect Correct answer

Compresses the source sentence into a fixed-size context vector

Correct Incorrect Correct answer

Generates the final translated sentence based on the context vector

Correct Incorrect Correct answer

Regularizes the translation to make it smoother

Correct Incorrect Correct answer

5. Question

In RNNs, what is the “vanishing gradient” problem?

A problem that occurs when gradients become too large during training

Correct Incorrect Correct answer

A problem that affects only convolutional neural networks

Correct Incorrect Correct answer

A problem that occurs when gradients become too small, causing the network to have difficulty learning long-range dependencies

Correct Incorrect Correct answer

A problem related to the excessive number of layers in deep networks

Correct Incorrect Correct answer

6. Question

Which direction(s) can RNNs process sequences?

Forward-only

Correct Incorrect Correct answer

Backward-only

Correct Incorrect Correct answer

Random order

Correct Incorrect Correct answer

Bidirectional (both forward and backward)

Correct Incorrect Correct answer

7. Question

What is the primary motivation behind the development of Long Short-Term Memory (LSTM) networks?

To introduce parallelization in sequential data tasks

Correct Incorrect Correct answer

To address the vanishing gradient problem in standard RNNs

Correct Incorrect Correct answer

To improve convolutional neural networks for image processing tasks

Correct Incorrect Correct answer

To enhance the interpretability of neural networks

Correct Incorrect Correct answer

8. Question

What is the essential architectural difference between LSTMs and standard RNNs?

LSTMs have a fixed architecture, while RNNs have a flexible architecture

Correct Incorrect Correct answer

LSTMs have a deeper architecture than standard RNNs

Correct Incorrect Correct answer

LSTMs use convolutional layers in their architecture

Correct Incorrect Correct answer

LSTMs introduce gating mechanisms, while standard RNNs do not have such mechanisms
