Some FAQ:
❓ What is data collection for machine learning?
Data collection involves gathering raw data from various sources to create a large, diverse, and relevant dataset that can be used to train machine learning models.

❓ How do I collect data for machine learning?
Depending on the project's needs, data can be collected through surveys, collaboration with research labs, public engagement initiatives, or web scraping for data science.

❓ What is web scraping in machine learning?
Web scraping is extracting data from websites using custom-made code, web scraping libraries, APIs, or codeless tools. It's a powerful technique for gathering public web data at scale.

❓ How can I ensure data quality?
Ensure data quality by focusing on accuracy, completeness, consistency, and relevance. Regular data cleansing and careful source selection are crucial to preventing issues like AI hallucinations.

❓ What are AI hallucinations?
AI hallucinations occur when a model produces misleading or false results due to poor-quality or inaccurate training data, leading to what's known as a "model collapse."

❓ What's the difference between supervised and unsupervised learning?
Supervised learning uses labeled data to recognize existing patterns and solve known problems, while unsupervised learning explores data to find patterns without predefined labels.
