A Network Analysis of Game of Thrones

Jon Snow, Daenerys Targaryen, or Tyrion Lannister? Who is the most important character in Game of Thrones? Let's see what mathematics can tell us about this!

In this project, you will look at the character co-occurrence network and its evolution over the five books in R.R. Martin's hugely popular book series A Song of Ice and Fire (perhaps better known as the TV show Game of Thrones ). You will look at how the importance of the characters changes over the books using different centrality measures.

This project uses a dataset parsed by Andrew J. Beveridge and Jie Shan which is available here . For more information on this dataset have a look at the Network of Thrones blog .

A New Era of Data Analysis in Baseball

There's a new era of data analysis in baseball. Using a new technology called Statcast, Major League Baseball is now collecting the precise location and movements of its baseballs and players. In this project, you will use Statcast data to compare the home runs of two of baseball's brightest (and largest) stars, Aaron Judge (6'7") and Giancarlo Stanton (6'6"), both of whom now play for the New York Yankees.

The dataset used in this project is from Baseball Savant .

A Visual History of Nobel Prize Winners

The Nobel Prize is perhaps the world's most well known scientific award. Every year it is given to scientists and scholars in chemistry, literature, physics, medicine, economics, and peace. The first Nobel Prize was handed out in 1901, and at that time the prize was Eurocentric and male-focused, but nowadays it's not biased in any way. Surely, right?

Well, let's find out! What characteristics do the prize winners have? Which country gets it most often? And has anybody gotten it twice? It's up to you to figure this out.

The dataset used in this project is from The Nobel Foundation on Kaggle.

Analyze Your Runkeeper Fitness Data

With the explosion in fitness tracker popularity, runners all of the world are collecting data with gadgets (smartphones, watches, etc.) to keep themselves motivated. They look for answers to questions like:

• How fast, long, and intense was my run today?
• Have I succeeded with my training goals?
• Am I progressing?
• What were my best achievements?
• How do I perform compared to others?

I exported seven years worth of my training data from Runkeeper . The data is a CSV file where each row is a single training activity. In this project, you'll create import, clean, and analyze my data to answer the above questions. You can then apply the same strategy to your training data if you wish!

Bad passwords and the NIST guidelines

Almost every web service you join will require you to come up with a password. But what makes a good password? In June 2017 the National Institute of Standards and Technology (NIST) published publication 800-63B titled Digital Identity Guidelines: Authentication and Lifecycle Management . This publication doesn't tell you what is a good password, but it does have specific rules for what is a bad password.

In this project, you will take a list of user passwords and, using publication 800-63B, you will write code that automatically detects and flags the bad passwords.

Book Recommendations from Charles Darwin

Recommendation systems are at the heart of many products such as Netflix or Amazon. They generally rely on metadata (e.g., the actors or director of a movie) or on user tastes (e.g., the movies you liked before) to determine which you are most likely to enjoy. But when you are working with text-heavy datasets, you have access to a much richer resource—the whole text! In this project, you will learn how to build the basis of a book recommendation system based on their content. You will use Charles Darwin's bibliography to find out which books might interest you.

The dataset was manually collected from Project Gutenberg .

Comparing Cosmetics by Ingredients

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's tought to interpret those ingredient lists unless you have a background in chemistry.

Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. In this Project, you are going to create a content-based recommendation system where the 'content' will be the chemical components of cosmetics. Specifically, you will process ingredient lists for 1472 cosmetics on Sephora via word embedding , then visualize ingredient similarity using a machine learning method called t-SNE and an interactive visualization library called Bokeh.

Disney Movies and Box Office Success

Since the 1930s, Walt Disney Studios has released more than 600 films covering a wide range of genres. While some movies are indeed directed towards kids, many are intended for a broad audience. In this project, you will analyze data to see how Disney movies have changed in popularity since its first movie release. You will also perform hypothesis testing to see what aspects of a movie contribute to its success.

This project assumes that you can manipulate data using pandas and can make basic plots using Seaborn. You should also be familiar with statistical inference and be able to perform two-sample bootstrap hypothesis tests for difference of means. The prerequisites for this project are Introduction to Linear Modeling in Python and Introduction to Seaborn .

The dataset used in this project is a modified version of the Disney Character Success dataset from Kelly Garrett .

Do Left-handed People Really Die Young?

Barack Obama is left-handed. So are Bill Gates and Oprah Winfrey; so were Babe Ruth and Marie Curie. A 1991 study reported that left-handed people die on average nine years earlier than right-handed people. Nine years! Could this really be true?

In this project, you will explore this phenomenon using age distribution data to see if we can reproduce a difference in average age at death purely from the changing rates of left-handedness over time, refuting the claim of early death for left-handers. This notebook uses pandas and Bayesian statistics to analyze the probability of being a certain age at death given that you are reported as left-handed or right-handed.

Exploring the Evolution of Linux

Version control repositories like CVS, Subversion or Git store rich evolution information about a software project. In this project, you'll be challenged to read in, clean up and visualize a real world Git repository dataset of the Linux kernel. With almost 700k commits and thousands of contributors (find out the exact number in this project ;-) ) there are some little data cleaning and wrangling challenges that you'll encounter. But you'll also gain insights about the development activities over the last 13 years.

For this Project, you need to be familiar with Pandas DataFrame s, especially the read_csv and groupby functions, as well as working with time series data.

Predicting Credit Card Approvals

Commercial banks receive a lot of applications for credit cards. Many of them get rejected for many reasons, like high loan balances, low income levels, or too many inquiries on an individual's credit report, for example. Manually analyzing these applications is mundane, error-prone, and time-consuming (and time is money!). Luckily, this task can be automated with the power of machine learning and pretty much every commercial bank does so nowadays. In this project, you will build an automatic credit card approval predictor using machine learning techniques, just like the real banks do.

The dataset used in this project is the Credit Card Approval dataset from the UCI Machine Learning Repository.

Real-time Insights from Social Media Data

Fear of missing out, curiosity, self-esteem, speed: it's like social media has changed our basic human needs; these baits are keeping us hooked and engaged. And Twitter is a master at this game . Elon Musk's tweets keep Wall Street on its toes; Trump's tweets have the potential of starting wars — Twitter has this huge influence on the world because of the type of its users. Data from Twitter-storms is available in near real-time. This means we can learn about the big waves of thoughts and moods around the world as they arise. So of course, we are not going to miss the chance to analyze this treasure trove.

In this Project, you will use pre-downloaded datasets to understand the nuts and bolts of Twitter Data. In particular, you will do a thorough analysis of a hot-trend.

Warning: Some of the tweets in the Twitter datasets contain explicit language.

Recreating John Snow's Ghost Map

In 1854, Dr. John Snow (no, not the Game of Thrones's character) used a pre-computer method of spatial analysis by mapping patterns and occurrences of cholera outbreaks in Soho, London. He mapped the deaths in the neighbourhood and determined that a vast majority occurred around one particular water well and that those that died used that well.

This is not only one of the earliest uses of data visualization, but by solving this problem, Dr. John Snow also founded spatial analysis and modern epidemiology. In this Python project, you will reanalyze the data and recreate his famous map.

Risk and Returns: The Sharpe Ratio

When you assess whether to invest in an asset, you want to look not only at how much money you could make but also at how much risk you are taking. The Sharpe Ratio, developed by Nobel Prize winner William Sharpe some 50 years ago, does precisely this: it compares the return of an investment to that of an alternative and relates the relative return to the risk of the investment, measured by the standard deviation of returns.

In this project, you will apply the Sharpe ratio to real financial data using pandas.

TV, Halftime Shows, and the Big Game

Whether or not you like football, the Super Bowl is a spectacle. There's drama in the form of blowouts, comebacks, and controversy in the games themselves. There are the ridiculously expensive ads, some hilarious, others gut-wrenching, thought-provoking, and weird. The half-time shows with the biggest musicians in the world, sometimes riding giant mechanical tigers or leaping from the roof of the stadium . And in this project, you will find out how some of the elements of this show interact with each other. You will answer questions like:

• What are the most extreme game outcomes?
• How does the game affect television viewership?
• How have viewership, TV ratings, and ad cost evolved over time?
• Who are the most prolific musicians in terms of halftime show performances?

The dataset used in this project was scraped and polished from Wikipedia. It is made up of three CSV files, one with game data , one with TV data , and one with halftime musician data for all 52 Super Bowls through 2018.

The Android App Market on Google Play

Mobile apps are everywhere. They are easy to create and can be lucrative. Because of these two factors, more and more apps are being developed. In this project, you will do a comprehensive analysis of the Android app market by comparing over ten thousand apps in Google Play across different categories. You'll look for insights in the data to devise strategies to drive growth and retention.

The data for this project was scraped from the Google Play website. While there are many popular datasets for Apple App Store, there aren't many for Google Play apps, which is partially due to the increased difficulty in scraping the latter as compared to the former. The data files are as follows:

• apps.csv : contains all the details of the applications on Google Play. There are 13 features that describe a given app.

The GitHub History of the Scala Language

Open source projects contain entire development histories, such as who made changes, the changes themselves, and code reviews. In this project, you'll be challenged to read in, clean up, and visualize the real-world project repository of Scala that spans data from a version control system (Git) as well as a project hosting site (GitHub). With almost 30,000 commits and a history spanning over ten years, Scala is a mature language. You will find out who has had the most influence on its development and who are the experts.

The dataset includes the project history of Scala retrieved from Git and GitHub as a set of CSV files.

The Hottest Topics in Machine Learning

Neural Information Processing Systems (NIPS) is one of the top machine learning conferences in the world where groundbreaking work is published. In this Project, you will analyze a large collection of NIPS research papers from the past decade to discover the latest trends in machine learning. The techniques used here to handle large amounts of data can be applied to other text datasets as well.

Familiarity with Python and pandas is required to complete this Project, as well as experience with Natural Language Processing in Python ( sklearn specifically).

Up and Down With the Kardashians

While I'm not a fan nor a hater of the Kardashians and Jenners, the polarizing family intrigues me. Why? Their marketing prowess. Say what you will about them and what they stand for, they are great at the hype game. Everything they touch turns to content.

In this Project, you will explore the data underneath the hype in the form of search interest data from Google Trends. You'll recreate the Google Trends plot to visualize their ups and downs over time, then make a few custom plots of your own. And you'll answer the big question: is Kim even the most famous sister anymore?

Who's Tweeting? Trump or Trudeau?

Let's apply our natural language processing knowledge to Twitter. Tweets are notoriously difficult, as they are shorter than most texts and usually have hard-to-parse content like hashtags, mentions, links and emoji.

Despite the difficulties, tweets are fun content, so in this notebook we'll take a look at classifying two prominent North American politicians. Can we determine if it is Donald Trump or Justin Trudeau based on just a tweet? Let's see!

Word Frequency in Classic Novels

Jon Snow, Daenerys Targaryen, or Tyrion Lannister? Who is the most important character in Game of Thrones? Let's see what mathematics can tell us about this!

In this project, you will look at the character co-occurrence network and its evolution over the five books in R.R. Martin's hugely popular book series A Song of Ice and Fire (perhaps better known as the TV show Game of Thrones ). You will look at how the importance of the characters changes over the books using different centrality measures.

This project uses a dataset parsed by Andrew J. Beveridge and Jie Shan which is available here . For more information on this dataset have a look at the Network of Thrones blog .
