Supervised Learning

Machine learning approaches that use labeled data to train models for specific tasks, such as classification or regression.

Unsupervised Learning

Machine learning approaches that use unlabeled data to discover patterns and insights, such as clustering or dimensionality reduction.

Regression

Types of machine learning problems that involve predicting a numerical value, such as stock prices or house prices.

Classification

A type of machine learning problem that involves predicting a category or label, such as whether an email is spam or not.

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

  • The Big Data ecosystem includes:
    • Distributed file systems
    • Distributed programming framework
    • Data integration framework
    • Machine learning framework
    • No SQL Databases
    • Scheduling tools
    • Benchmarking tools
    • System deployments
