Chapter 1 Introduction

This is an analysis based on Kaggle survey data, details are at Kaggle is a subsidiary of Google LLC online community of data scientists machine learners. It offers data sets, a no-setup, customizable, Jupyter Notebooks environment, machine learning competitions and access free GPUs and a huge repository of community published data & code.

  • The survey received 19,717 usable respondents from 171 countries and territories. If a country or territory received less than 50 respondents, they were grouped and named “Other” for anonymity.

  • The survey was live from October 8th to October 28th 2019.

  • The median response time for those who participated in the survey was approximately 10 minutes.

An overview of the world wide participation is given in the map below. The first three countries are

  • India
  • USA
  • Brazil

All numbers of all countries are given in the interactive table below. To find a specific country, type the name in the search field. Surprising facts:

  • Almost as many participants from Saudi Arabia (50) and Norway (51)
  • Peru (74) higher than Belgium (70)
  • Iran (96) higher than Sweden (92)

1.1 Purpose

The purpose of the survey analysis is to create insight into which

  • algorithms
  • tools
  • platforms

are used in the field of machine learning. Contrary to public opinion machine learning is not mainly focused on neural networks.

1.2 Results

The results are presented by graphs relating parameters either vs time or vs other parameters.
