Study Notes
Introduction to Data Science
- Data science involves extracting meaningful insights from large sets of data.
- Example: A small retail shop owner tracks transactions to determine profitability and stock needs, using experience and basic math skills.
- Artificial Intelligence (AI) relies heavily on data, which drives its capabilities.
Applications of Data Science
- Fraud and Risk Detection: Financial institutions use data science to predict bad debts during loan processing through customer behavior analysis.
- Genetics and Genomics: Supports advanced treatments like gene therapy by integrating various data types for a deeper understanding of genetic issues.
- Internet Search: Search engines utilize data science to provide relevant information rapidly, enhancing user experience.
- Targeted Advertising: Companies employ data science to optimize advertising methods based on consumer behavior for improved engagement.
Types of Data Formats
- CSV (Comma-Separated Values): A simple format for storing tabular data, where each line is a record and fields are separated by commas.
- Spreadsheet: Used for data recording in rows and columns; Microsoft Excel is a common tool for creating spreadsheets.
- SQL (Structured Query Language): A domain-specific programming language for managing data in various database systems, particularly useful for structured data.
Data Access in Python
- Python packages help in accessing structured data effectively.
- Key packages include:
- NumPy: Fundamental for numerical operations on arrays, allowing arithmetic operations and creation of n-dimensional arrays (ND-arrays).
- Pandas: Designed for data manipulation and analysis, excellent for tabular and time series data; features primary structures like Series and DataFrame.
- Matplotlib: Visualization library for creating 2D plots, aiding in data interpretation through visual representations.
NumPy
- Stands for Numerical Python; essential for mathematical operations on arrays.
- Supports complex calculations and operations on homogeneous sets of data (arrays).
- Features n-dimensional arrays, enhancing data manipulation capabilities.
Pandas
- Ideal for data manipulation; built on NumPy.
- Handles various forms of data, including tabular data with mixed types and time series.
- Primary structures:
- Series: 1-dimensional data structure.
- DataFrame: 2-dimensional data structure.
- Offers capabilities like handling missing data, column mutability, intelligent data alignment, and easy data merging.
Matplotlib
- Visualization library available for creating 2D plots from arrays.
- Facilitates comprehension of large data sets through visual representation.
- Supports various plot types, aiding in the identification of trends and patterns.
