Core Data Science Libraries
Programming libraries support data science workflows with pre-built functions for statistical analysis, machine learning, and data manipulation. Python is widely used in data science for its numerical computing libraries, while R remains popular in academic research and statistical modelling. SQL databases handle structured queries over data, whereas NoSQL systems accept unstructured data, such as text, images, and sensor data.
The essential data science libraries include:
Pandas: Provides data manipulation and analysis functions, enabling effective work with big structured data. It is faster than traditional spreadsheets because it processes data in memory, uses vectorized operations, and efficiently manages large volumes of data.
NumPy: Enables numerical computing in Python through vectorized operations, which are generally faster than standard Python loops. It also supports many other Python data science libraries.
Scikit-learn: Provides 150+ machine learning algorithms used in classification, regression, and clustering. It also has a stable API, which simplifies the switching and implementation of algorithms.
TensorFlow: A deep learning platform by Google for neural networks, supporting large models and distributed training across multiple GPUs.
PyTorch: It is an open-source library developed by Facebook, capable of creating neural networks in their dynamic form, with a flexible architecture. It has been widely adopted in the research community.
R tidyverse: Creates integrated data science workflows through consistent R package collections, providing uniform syntax for data manipulation and integrating seamlessly with statistical modeling functions.
Apache Spark: Processes big data with distributed computing across clusters, using terabytes of data effectively, and Spark SQL allows standard database queries of big data.
