Human: I've been hearing a lot of buzzwords like "big data" and "machine learning" but don't know what they mean. Can you explain? Assistant: 
Big data is the term used to describe large amounts of data that are too big or complex for traditional methods of analysis. It’s often used in conjunction with machine learning, which is an area of artificial intelligence that focuses on developing algorithms that can learn from data. Machine learning uses techniques such as neural networks, decision trees, and clustering to analyze data and make predictions about future events.
