Study Notes
Introduction to Data Science
- Data Science is the discipline that deals with the collection, processing, management, analysis, interpretation, and visualization of large, heterogeneous, and complex datasets.
- The goals are extracting non-obvious and useful information, knowledge from big data, in order to improve scientific, social and business decision making.
- Data Scientist's goal is to solve a scientific or business problem, not just analyze the data or build a predictive model.
The Value of Data
- Data is the raw material of science and business.
- Data leads to evidence, understanding, and progress.
Applications of Data Science
- Recommendation Systems
- Autonomous Vehicle Control/Robotics
- Personalized Medicine/Genomics
- Personal Assistants/Voice Recognition
Data Science Skill Set
- Data Science = Data Analytical Thinking + Automation
Data Scientist
- Responsible for guiding the Data Science Project from start to end.
- Requires quantifiable goals, good methodologies, cross-disciplinary interactions, and a repeatable workflow.
