Foreword
I had a background in econometrics but became interested in machine learning techniques, ini-
tially as an alternative approach to solving forecasting problems. As I started discovering my
interest, I found the field intimidating to enter: I didn’t know the techniques, the terminology,
and didn’t have the credentials that would allow me to break in.
It was always my dream that Kaggle would allow people like me the opportunity to break into
this powerful new field. Perhaps the thing I’m proudest of is the extent to which Kaggle has made
data science and machine learning more accessible. We’ve had many Kagglers go from newbies
to top machine learners, being hired at places like NVIDIA, Google, and OpenAI, and starting
companies like DataRobot.
Luca and Konrad’s book helps make Kaggle even more accessible. It offers a guide to both how
Kaggle works, as well as many of the key learnings that they have taken out of their time on the
site. Collectively, they’ve been members of Kaggle for over 20 years, entered 330 competitions,
made over 2,000 posts to Kaggle forums, and shared over 100 notebooks and 50 datasets. They
are both top-ranked users and well-respected members of the Kaggle community.
Those who complete this book should expect to be able to engage confidently on Kaggle – and
engaging confidently on Kaggle has many rewards.
Firstly, it’s a powerful way to stay on top of the most pragmatic developments in machine learn-
ing. Machine learning is moving very quickly. In 2019, over 300 peer reviewed machine learning
papers were published per day. This volume of publishing makes it impossible to be on top of
the literature. Kaggle ends up being a very valuable way to filter what developments matter on
real-world problems – and Kaggle is useful for more than keeping up with the academic litera-
ture. Many of the tools that have become standard in the industry have spread via Kaggle. For
example, XGBoost in 2014 and Keras in 2015 both spread through the community before making
their way into industry.
Secondly, Kaggle offers users a way to “learn by doing.” I’ve heard active Kagglers talk about com-
peting regularly as “weight training” for machine learning. The variety of use cases and problems
they tackle on Kaggle makes them well prepared when they encounter similar problems in indus-
try. And because of competition deadlines, Kaggle trains the muscle of iterating quickly. There’s
probably no better way to learn than to attempt a problem and then see how top performers
tackled the same problem (it’s typical for winners to share their approaches after the competition).
So, for those of you who are reading this book and are new to Kaggle, I hope it helps make Kaggle
less intimidating. And for those who have been on Kaggle for a while and are looking to level up,
I hope this book from two of Kaggle’s strongest and most respected members helps you get more
out of your time on the site.

About the authors
Konrad Banachewicz holds a PhD in statistics from Vrije Universiteit Amsterdam. During his
period in academia, he focused on problems of extreme dependency modeling in credit risk. In
addition to his research activities, Konrad was a tutor and supervised master’s students. Starting
from classical statistics, he slowly moved toward data mining and machine learning (this was
before the terms “data science” or “big data” became ubiquitous).
In the decade after his PhD, Konrad worked in a variety of financial institutions on a wide array
of quantitative data analysis problems. In the process, he became an expert on the entire lifetime
of a data product cycle. He has visited different ends of the frequency spectrum in finance (from
high-frequency trading to credit risk, and everything in between), predicted potato prices, and
analyzed anomalies in the performance of large-scale industrial equipment.
As a person who himself stood on the shoulders of giants, Konrad believes in sharing knowledge
with others. In his spare time, he competes on Kaggle (“the home of data science”).
I would like to thank my brother for being a fixed point in a chaotic world and continuing to provide
inspiration and motivation. Dzięki, Braciszku.
Luca Massaron is a data scientist with more than a decade of experience in transforming data
into smarter artifacts, solving real-world problems, and generating value for businesses and
stakeholders. He is the author of bestselling books on AI, machine learning, and algorithms. Luca
is also a Kaggle Grandmaster who reached no. 7 in the worldwide user rankings for his perfor-
mance in data science competitions, and a Google Developer Expert (GDE) in machine learning.
My warmest thanks go to my family, Yukiko and Amelia, for their support and loving patience as I prepared
this new book in a long series.
My deepest thanks to Anthony Goldbloom for kindly writing the foreword for this book and to all the Kaggle
Masters and Grandmasters who have so enthusiastically contributed to its making with their interviews,
suggestions, and help.
Finally, I would like to thank Tushar Gupta, Parvathy Nair, Lucy Wan, Karan Sonawane, and all of the
Packt Publishing editorial and production staff for their support on this writing effort.
About the reviewer
Dr. Andrey Kostenko is a data science and machine learning professional with extensive expe-
rience across a variety of disciplines and industries, including hands-on coding in R and Python
to build, train, and serve time series models for forecasting and other applications. He believes
that lifelong learning and open-source software are both critical for innovation in advanced
analytics and artificial intelligence.
Andrey recently assumed the role of Lead Data Scientist at Hydroinformatics Institute (H2i.sg), a
specialized consultancy and solution services provider for all aspects of water management. Prior
to joining H2i, Andrey had worked as Senior Data Scientist at IAG InsurTech Innovation Hub for
over 3 years. Before moving to Singapore in 2018, he worked as Data Scientist at TrafficGuard.
ai, an Australian AdTech start-up developing novel data-driven algorithms for mobile ad fraud
detection. In 2013, Andrey received his doctorate degree in Mathematics and Statistics from
Monash University, Australia. By then, he already had an MBA degree from the UK and his first
university degree from Russia.
In his spare time, Andrey is often found engaged in competitive data science projects, learning new
tools across R and Python ecosystems, exploring the latest trends in web development, solving
chess puzzles, or reading about the history of science and mathematics.
Dr. Firat Gonen is the Head of Data Science and Analytics at Getir. Gonen leads the data sci-
ence and data analysis teams delivering innovative and cutting edge Machine Learning projects.
Before Getir, Dr. Gonen was managing Vodafone Turkey’s AI teams. Prior to Vodafone Turkey, he
was the Principal Data Scientist at Dogus Group (one of Turkey’s largest conglomerates). Gonen
holds extensive educational qualifications including a PhD degree in NeuroScience and Neural
Networks from University of Houston and is an expert in Machine Learning, Deep Learning, Visual
Attention, Decision-Making & Genetic Algorithms with over more than 12 years in the field. He
has authored several peer-review journal papers. He’s also a Kaggle Triple GrandMaster and has
more than 10 international data competition medals. He was also selected as the 2020 Z by HP
Data Science Global Ambassador.
