Data Science
What is data science?
Data science is a field focused on extracting insights from data through statistical analysis, machine learning techniques, and computational methods. It combines critical thinking with technical skills to turn raw data into actionable insights.
Data science practitioners typically use tools like Python and Jupyter Notebooks for their work, as these tools facilitate data manipulation, analysis, and visualization.
How does data science relate to AI product development?
Many techniques used in AI product development—like error analysis, evals, and model evaluation—come from the data science world of machine learning. When you're building and evaluating AI products, you're essentially doing data science work.
The core methodology involves:
- Looking at data and analyzing it
- Figuring out what's going wrong
- Forming hypotheses about the problems
- Writing evals to test those hypotheses
- Looking at the results and aligning them with human judgment
- Iterating based on what you learn
This iterative, hypothesis-driven approach is fundamental to both data science and building effective AI products.
What skills does data science require?
Data science requires strong critical thinking skills alongside technical capabilities. You need to be able to:
- Identify patterns and anomalies in data
- Form meaningful hypotheses about what you're observing
- Design tests to validate or refute those hypotheses
- Interpret results and understand their implications
- Communicate insights clearly to others
For AI product teams, learning data science techniques—even at a basic level—helps you understand how your AI system is performing and what changes might improve it. You don't need to be a data scientist to apply data science thinking to your AI work.
