    Study Notes

    Data Science

    • Data science is a vaguely defined concept with two meanings: doing science based on (big) data, and the science of working with data.

    Venn Diagrams

    • Data science is represented in Venn diagrams, which encompass Data Mining Methods, Preprocessing, Transformation, Evaluation, Material, and Summary.

    Data Mining Methods

    • Data mining methods include Frequency Pattern Mining, Feature Spaces, Clustering – Basics, Classification – Basics, Bayesian Learning, Learning with Distributions, Entropy, Purity, and (Non-)Linear Separation.

    Ensemble Learning

    • Ensemble Learning is a data mining method.
    • It involves learning from data and finding patterns in data.
    • Different methods deliver different pictures of the data.

    KDD Process Model

    • The KDD Process Model is a method for selecting relevant attributes and generating new attributes.

    Data Science Goals

    • The goal of data science is to select relevant attributes and generate new ones.
    • It aims to understand databases and find patterns in data.

    Course Objectives

    • The course aims to help students understand methods for analyzing data and learning from data.
    • It covers data mining/machine learning, which are computational methods for learning from data.
