1. Intro

"I think, therefore I am"
  • What is data science?
  • What type of questions can be answered?
  • Frame / Acquire / Refine / Explore / Model / Insight framework

2. Frame

"The framing of a problem is often far more essential than its solution"
  • How to frame a data science problem?
  • Learn the hypothesis-driven approach?
  • How do you start - question driven, dataset driven or both?

3. Acquire

"Data is the new oil"
  • Sources of Data
    • Download from an internal system
    • Obtained from client or other 3rd party
    • Extracted from a web-based API
    • Scraped from a website / pdfs
    • Gathered manually and recorded
    • Acquire data from a csv file or a database
    • Acquire data from a 3rd part client (e.g. twitter)

4. Explore

"I don't know, what I don't know"
  • Why do visual exploration?
  • Understand Data Structure & Types
  • Grammar of Graphics and Basics of visualisation
  • Explore single variable graphs - (Quantitative, Categorical)

  • Aggregate - rollup by year, cluster by area
  • Filter - exclude based on location
  • Sample - extract a representative data
  • Summary - show summary stats like mean
  • Basic statistics: variance, standard deviation, co-variance, correlation

6. Model

  • Regularization
    • L1 regularization
    • L2 regularization
  • Classification model
  • Decision Trees
    • Visualizing decision trees

7. Insight

"The goal is to turn data into insight"
