Interview Questions and Answers
Freshers / Beginner level questions & answers
Ques 1. What is Hugging Face, and why is it popular?
Hugging Face is an open-source platform that provides NLP models and datasets. It became popular for its Transformer library, which simplifies using state-of-the-art models like BERT, GPT, and others for tasks such as text classification, summarization, and translation.
Example:
You can use Hugging Face to easily load a pre-trained model like GPT-3 for text generation tasks with minimal code.
Ques 2. What is the Transformers library in Hugging Face?
The Transformers library is a Python-based library by Hugging Face that provides tools to work with transformer models like BERT, GPT, T5, etc. It allows developers to load pre-trained models and fine-tune them for various NLP tasks.
Example:
Using the Transformers library, you can load BERT for a sentiment analysis task with a few lines of code.
Ques 3. What are some key tasks Hugging Face models can perform?
Hugging Face models can perform various NLP tasks such as text classification, named entity recognition (NER), question answering, summarization, translation, and text generation.
Example:
A common task would be using a BERT model for question-answering applications.
Ques 4. How do you load a pre-trained model from Hugging Face?
To load a pre-trained model from Hugging Face, use the 'from_pretrained' function. You can specify the model name, such as 'bert-base-uncased'.
Example:
from transformers import AutoModel
model = AutoModel.from_pretrained('bert-base-uncased')
Ques 5. What are pipelines in Hugging Face?
Pipelines are easy-to-use interfaces provided by Hugging Face for performing NLP tasks without needing to manage models, tokenizers, or other components. The pipeline API abstracts the complexity.
Example:
from transformers import pipeline
classifier = pipeline('sentiment-analysis')
result = classifier('Hugging Face is great!')
Ques 6. What is the Hugging Face Hub, and how does it work?
Hugging Face Hub is a platform for sharing, discovering, and managing models, datasets, and metrics. Users can upload their models and datasets for others to use in NLP tasks.
Example:
Uploading a fine-tuned BERT model to Hugging Face Hub for public use.
Ques 7. How do you measure the performance of Hugging Face models?
You can measure performance using metrics such as accuracy, precision, recall, F1-score, and perplexity. Hugging Face also provides evaluation libraries like 'evaluate' to automate this.
Example:
Using Hugging Face’s 'evaluate' library for computing the accuracy of a text classification model.
