"Zeer enthousiast bij het geven van de workshop. De workshop was gestructureerd opgebouwd. Van eenvoudige materie on een vloeiende overgang naar complexe materie op een simpele manier uitgelegd waardoor deze goed te volgen was.
De combinatie tussen praktijk voorbeelden en theoretische uitleg maakte de materie concreet waardoor de complexe materie goed te volgen was.
De kennis en workshop was up-to-date en maakte de workshop zeer interessant. " - 14-11-2020 08:34

Description

Introduction

Apache Spark is an open-source distributed engine for querying and processing data. In this three-day hands-on workshop, you will learn how to leverage Spark from Python to process large amounts of data.

After a presentation of the Spark architecture, we'll begin manipulating Resilient Distributed Datasets (RDDs) and work our way up to Spark DataFrames. The concept of lazy execution is discussed in detail and we demonstrate various transformations and actions specific to RDDs and DataFrames. You'll learn how DataFrames can be manipulated using SQL queries.

We'll show you how to apply supervised machine learning models such as linear regression, logistic regression, decision tree…

Introduction

Apache Spark is an open-source distributed engine for querying and processing data. In this three-day hands-on workshop, you will learn how to leverage Spark from Python to process large amounts of data.

After a presentation of the Spark architecture, we'll begin manipulating Resilient Distributed Datasets (RDDs) and work our way up to Spark DataFrames. The concept of lazy execution is discussed in detail and we demonstrate various transformations and actions specific to RDDs and DataFrames. You'll learn how DataFrames can be manipulated using SQL queries.

We'll show you how to apply supervised machine learning models such as linear regression, logistic regression, decision trees, and random forests. You'll also see unsupervised machine learning models such as PCA and K-means clustering.

By the end of this workshop, you will have a solid understanding of how to process data using PySpark and you will understand how to use Spark's machine learning library to build and train various machine learning models.

What you'll learn

  • Learn about Apache Spark and the Spark architecture and its components
  • Work with RDDs and lazy evaluation
  • Build and interact with Spark DataFrames using Spark SQL
  • Use Spark SQL and DataFrames to process data using traditional SQL queries
  • Apply a spectrum of supervised and unsupervised machine learning algorithms
  • Handle issues related to feature engineering, class imbalance, bias and variance, and cross validation for building an optimal fit model

This workshop is for you because

  • You work with data regularly and want to be able to scale up the quantity of data processed
  • You want to understand the methods specific to Spark for wrangling data
  • You want to learn how to apply machine learning algorithms to large amounts of data

Schedule

Day 1:

  • Introduction to Apache Spark
    • Setting up Spark
    • Spark fundamentals
    • Spark architecture
  • Resilient Distributed Datasets (RDDs)
    • Getting data into Spark
    • Actions
    • Transformations

Day 2:

  • DataFrames
    • Speeding up PySpark with DataFrames
    • Creating DataFrames
    • Interoperating with RDDs
    • Querying with the DataFrame API
  • Querying DataFrames with SQL

Day 3:

  • ML and MLLib packages
    • API Overview
    • Pipelines
    • Transformers
    • Estimators
  • Applying Machine Learning
    • Validation
    • Classification
    • Regression
    • Recommender system
  • Where to go from here

Prerequisites

Participants are expected to be familiar with the following Python syntax and concepts:

  • assignment, arithmetic, boolean expression, tuple unpacking
  • bool, int, float, list, tuple, dict, str, type casting
  • in operator, indexing, slicing
  • if, elif, else, for, while
  • range(), len(), zip()
  • def, (keyword) arguments, default values
  • import, import as, from import ...
  • lambda functions, list comprehension
  • JupyterLab or Jupyter Notebook

Some experience with Pandas and SQL is useful, but not required.

Recommended preparation

Participants are kindly requested to have the following items installed prior to the start of the workshop:

  • Docker Desktop for Windows or for Mac or for Ubuntu
  • The docker image, by running: docker pull jupyter/pyspark-notebook

More detailed installation instructions will be provided by email after signup.

"I really enjoyed Jeroen's workshop, he explained the Spark basics (RDDs, dataframes,transformers,estimators,etc.) very well and the class included a lot of hands-on exercises (including building ML models). The training was given in-house in our company's office on three separate days." - 06-11-2020 15:41

"Ik heb de cursus Data Science with Python and Spark in 2019 gevolgd bij Jeroen Janssens. Jeroen weet complexe informatie op een begrijpelijke manier over te brengen en combineerd in zijn trainingen theorie met hands-on opdrachten. Op die manier kun je aan het eind van de dag echt nieuwe vaardigheden toepassen. Ook de andere cursussen van datascienceworkshops.com kan ik trouwens ten zeerste aanraden!" - 05-11-2020 10:22

"Even experienced data scientists need to keep working on their skills and knowledge. For the past half a year, Data Science Workshops has come to our office once a month, to teach us about a variety of topics, ranging from NoSQL to t-SNE. This is a great way to stay fresh and look beyond the tools and techniques that you’re already familiar with." - 31-10-2020 12:53
