Questions¶
1. What is the primary purpose of low-code ML tools?¶
A) To make machine learning inaccessible to non-experts
B) To simplify ML development and deployment with minimal coding
C) To replace traditional programming completely
D) To make ML models less accurate but faster
Answer
B) To simplify ML development and deployment with minimal coding
Low-code tools democratize ML by reducing the coding required for common tasks like creating interfaces, training models, and deployment.
2. Which of the following is NOT a low-code ML interface framework?¶
A) Gradio
B) Streamlit
C) TensorFlow
D) Hugging Face Spaces
Answer
C) TensorFlow
TensorFlow is a deep learning framework that requires significant coding. Gradio, Streamlit, and Hugging Face Spaces are designed for low-code interface development.
3. What does AutoML primarily automate?¶
A) Only data collection
B) Model selection and hyperparameter tuning
C) Only model deployment
D) Writing research papers
Answer
B) Model selection and hyperparameter tuning
AutoML automates the process of selecting the best model architecture and tuning its hyperparameters, along with other pipeline steps like preprocessing.
4. In Gradio, what is the purpose of gr.Interface()?¶
A) To create database connections
B) To create interactive ML demos with inputs and outputs
C) To train machine learning models
D) To manage user authentication
Answer
B) To create interactive ML demos with inputs and outputs
gr.Interface() is the main function in Gradio for creating simple interactive interfaces that connect input components to a function that produces outputs.
5. What is a key difference between Gradio and Streamlit?¶
A) Gradio is only for images, Streamlit is only for text
B) Gradio focuses on quick ML demos, Streamlit on full data apps
C) Gradio requires more code than Streamlit
D) Streamlit cannot deploy to the cloud
Answer
B) Gradio focuses on quick ML demos, Streamlit on full data apps
While both can build interfaces, Gradio is optimized for quick ML model demos, while Streamlit is designed for comprehensive data applications and dashboards.
7. In Streamlit, what is st.session_state used for?¶
A) To display the current time
B) To persist data across reruns
C) To check server status
D) To manage database connections
Answer
B) To persist data across reruns
st.session_state stores variables that persist across Streamlit reruns, essential for maintaining user interactions like counters or form data.
8. Which AutoML platform is known for fast training times?¶
A) Manual scikit-learn
B) PyCaret
C) FLAML
D) Keras
Answer
C) FLAML
FLAML (Fast and Lightweight AutoML) is specifically designed for fast training times with efficient search algorithms.
9. What is Hugging Face Spaces primarily used for?¶
A) Storing large datasets only
B) Hosting and sharing ML applications
C) Training models exclusively
D) Managing API keys
Answer
B) Hosting and sharing ML applications
Hugging Face Spaces provides free hosting for ML applications built with Gradio, Streamlit, or Docker, making it easy to share demos with the community.
10. What information is typically in a Hugging Face Space’s README.md frontmatter?¶
A) User passwords
B) Training data
C) SDK type and configuration (title, emoji, sdk)
D) Model weights
Answer
C) SDK type and configuration (title, emoji, sdk)
The README.md frontmatter in a Hugging Face Space contains metadata like the title, emoji, SDK type (Gradio/Streamlit), and other configuration options.
