For her final project during the bootcamp, recent graduate Anupama Garla looked into answering the question: Living in Los Angeles, should I build a backyard home for extra income? She began to build a tool, which homeowners could use to determine the potential income and the feasibility of such a project. From Anupama's point of view, this tool would be beneficial to both homeowners and people like her, who are in the market to rent or own in the area. Using publicly available Airbnb and LA Geo datasets, she first built a model that predicted the income of a property.
To merge his interest in live music with data science, recent graduate Gabriel Bond chose to create a content-based live music recommender during the bootcamp.
"The result of this exploration utilizes unsupervised learning techniques, audio feature extraction with the LibROSA Python library, and both the Spotify and Songkick APIs to generate a playlist of songs by artists with upcoming shows in the user’s city based on the user’s favorite artists," he wrote in a blog post about the project.
When bootcamp graduate Sami Ahmed isn't working on data science projects, he's most likely making music and thinking about his interest in audio more generally. He recently found that NASA and the University of Iowa host a "massive library of electromagnetic waves that happen to fall in the audible human frequency range," he wrote in a blog post. Looking to get his hands on this audio, he figured out how to quickly web scrape hundreds of hours of audio from NASA using Beautiful Soup.
For his final project at Metis, Michael trained a convolutional neural network auto-encoder to capture the essential visual features of artwork and developed a recommendation app that would compare a user-uploaded image of street art to a corpus of more than 35,000 images of fine art and then return those images of fine art, along with associated mediate, that were most similar.
For bootcamp graduate Catherine Magsino, karaoke is more than just an occasional hobby.
"I’ve grown up singing karaoke for as long as I remember – at home, at family parties, and at get-togethers with friends. It is not only one of my favorite hobbies, but also a big part of my own culture. So naturally, I decided to focus my final project on this great pastime," she wrote in a blog post about her project.
Bootcamp graduate Katherine Bell recently dove into the hiring practices of startups in the United States, analyzing whether or not hiring offshore talent makes economic sense.

For her final bootcamp project, Alison Glazer looked into Airbnb's smart pricing tool, which was introduced years ago but faced immediate problems. According to Alison, the biggest issue was that price suggestions were too low and hosts noticed their revenues decrease when using the tool.
When you think about recommendation systems, Netflix might come to mind first based on its ubiquity and power, writes bootcamp grad Molly Liebeskind in a blog post about her final project. But even while recommenders can be complex, Molly identifies two simple approaches (content-based filtering and collaborative filtering) that are good starting points to understanding how they work and to building one of your own.
Having lived in different parts of the world, Aisulu Omar realized the importance of addressing and navigating news media bubbles. She set out to create a news recommendation platform that would provide a balanced perspective for all.

"When we hear about an airplane accident, there are a few things we always want to know. Where did it happen? Is everyone okay? And, of course: why did it crash?" writes Aaron Wilson. Find out how he used data science to find answers.
While Bitcoin showcases a vast body of anecdotal evidence that argues its utility, or potential future utility, due to the pseudonymous nature of the blockchain as well as other factors, it's still hard to come across aggregate data that shows this behavior occurring on a consistent and measurable scale. To attempt to address this problem, Ahlborg took a close look at trading volumes on the Peer-to-Peer Bitcoin trading website Localbitcoins.com.
At a recent DataKind SF event, Ash was rather intrigued by the challenges faced in investigating wage theft and other labor violations not just throughout the nation, but also specific to California and the Bay Area regions.
The opioid epidemic is one of the major public health catastrophes for this generation of Americans; similar to what tobacco/smoking or HIV/AIDS were to earlier generations, the opioid epidemic appears to be this era’s defining public health crisis. Lee set out to build a model to predict opioid-related mortality on a county by county basis with location-based insights and interventions in mind as a larger goal.
Imagine you’re hosting a birthday party. Everyone’s having a great time, music’s playing, and the party is noisy. Suddenly, it’s time for birthday cake! It’s too loud to use Alexa, and rather than hunting for your phone or a remote control, what if you could simply raise an open hand while in mid-conversation, your smart home device would recognize that gesture, and turn off the music? And with the same gesture, you could dim the lights just as the candles are lit?
Although uniqueness and personalization are great selling points, keeping up with the fashion trend is still the major theme that runs throughout the retail fashion business.

With cannabis being legal for medicinal use in 31 states and recreational use in 9 states, there are thousands of dispensaries from which one can obtain pricing data to analyze.
Davis thought it was a good time to dive into cannabis pricing to build a model that outputs a price benchmark for dispensaries (a “dankstimate” in the vein of Zillow’s “zestimate”).
Xuan Qi's goal for her project was to "accurately match customers with hotel inventory in this highly competitive market." On a personal note, she writes that "as a mom, when I book a hotel, I would like the hotel to be family friendly, closer to the sightseeing, and relatively quiet. But, my standards would be different booking a romantic weekend for me and my husband. We would like to pick the hotels with great food, closer to bars, and musical events are a plus. "
Vladimir Lazovskiy Data scientist working at the intersection of machine learning, content creation, and media.
In this project, Vladimir tackles the question: what is the relationship between machine learning and optimization? He explores how delivery companies can use the power of machine learning to forecast travel times between two locations and use the genetic algorithm to find the best travel itinerary for each delivery truck.
Alex chose to work with music data because it is a type of audio that can evoke emotion in addition to thought. When she listens to music, she asks herself, "Why does a particular song make me feel happy or sad?" The key of a song helps determine the feeling and is made up of the tonic note and the mode. For this project, she aimed to predict the mode.
In San Francisco, human waste is a growing issue, both for the people who run into it and for the people who have no other option than to relieve themselves on public streets. Mattie built a model that predicted where and when human waste will show up, which could be used to better inform resource allocation for programs like San Francisco’s Pitstop (a program that brings portable bathrooms to areas that have high homeless populations).
Tim's project explores the conversations about climate change that took place on Twitter in March 2017.
