Study Notes
Data Science and Its Concepts
- Data Science is a field that deals with defining data, identifying benefits, and exploring uses of Big Data.
- Big Data has various facets, including Structured Data, Unstructured Data, Natural Language, Machine-generated Data, Graph-based or Network Data, Audio, Image, Video, and Streaming data.
Data Science Process
- The data science process involves six steps:
- Defining research goals
- Data retrieval
- Cleansing data and correcting errors as early as possible
- Integrating data from different sources
- Transforming data
- Exploratory data analysis
Data Science Process (Continued)
- The data science process also includes:
- Data modeling
- Model and variable selection
- Model execution
- Model diagnostic and model comparison
- Presentation and automation
Data Science Ecosystem
