Interview Questions and Answers
Experienced / Expert level questions & answers
Ques 1. How can you convert a PyTorch model to TensorFlow using Hugging Face?
Hugging Face provides tools to convert models between frameworks like PyTorch and TensorFlow. Use 'from_pt=True' when loading a model to convert a PyTorch model to TensorFlow.
Example:
model = TFAutoModel.from_pretrained('bert-base-uncased', from_pt=True)
Ques 2. How do you handle large datasets using Hugging Face?
Hugging Face's Datasets library supports streaming, memory mapping, and distributed processing to handle large datasets efficiently.
Example:
Using memory mapping to load a large dataset: dataset = load_dataset('dataset_name', split='train', streaming=True)
Ques 3. What is the role of attention mechanisms in transformer models?
Attention mechanisms allow transformer models to focus on different parts of the input sequence, making them more effective at processing long-range dependencies in text.
Example:
Attention helps the model attend to relevant parts of a sentence when translating from one language to another.
Ques 4. How can you deploy a Hugging Face model to production?
You can deploy Hugging Face models using platforms like AWS Sagemaker, Hugging Face Inference API, or custom Docker setups.
Example:
Deploying a BERT model on AWS Sagemaker for real-time inference.
Ques 5. What are attention masks, and how are they used in Hugging Face?
Attention masks are binary tensors used to distinguish between padding and non-padding tokens in input sequences, ensuring the model ignores padded tokens during attention calculation.
Example:
Using attention masks in BERT input processing to handle variable-length sequences.
Ques 6. How do you handle multi-label classification using Hugging Face?
For multi-label classification, you modify the model’s output layer and the loss function to support multiple labels per input, using models like BERT with a sigmoid activation function.
Example:
Fine-tuning BERT for multi-label text classification by adapting the loss function: torch.nn.BCEWithLogitsLoss()
Ques 7. What is the role of masked language modeling in BERT?
Masked language modeling is a pre-training task where BERT masks certain tokens in a sentence and trains the model to predict the missing words, allowing it to learn bidirectional context.
Example:
In a sentence like 'The cat [MASK] on the mat', BERT would predict the missing word 'sat'.
Ques 8. How do you train a Hugging Face model on custom datasets?
To train a Hugging Face model on a custom dataset, preprocess the data to the appropriate format, use a tokenizer, define a model, and use Trainer or custom training loops for training.
Example:
Preprocessing text data for a BERT classifier using Hugging Face's Tokenizer and Dataset libraries.
Ques 9. What is beam search, and how is it used in Hugging Face?
Beam search is a decoding algorithm used in text generation models to explore multiple possible outputs and select the most likely sequence. Hugging Face uses it in models like GPT and T5.
Example:
from transformers import AutoModelForSeq2SeqLM
model.generate(input_ids, num_beams=5)
Ques 10. What is BART, and how does it differ from BERT?
BART is a sequence-to-sequence model designed for text generation tasks, while BERT is used for discriminative tasks. BART combines elements of BERT and GPT, using both bidirectional and autoregressive transformers.
Example:
BART is used for tasks like summarization and translation, while BERT is used for classification.
