"I was in the first cohort and have witnessed the development of the Curriculum since I first began and believe it to be continuing to improve from a very good to an excellent base. The highlight of the program, undoubtedly, was the mentorship experience. Meeting with my mentor twice a week for numerous months while I coded my projects has proven to be invaluable in shortening the learning cycles. The program surpassed my already high expectations."


"They have produced an excellent curriculum which teaches data science effectively — lectures and exercises get you familiar with the material, and then project-based work helps you apply it. The mentors and TAs were responsive and helpful, and proactive in offering help and advice. By the end of the program, you’ll be familiar with pretty much every tool and technique used by data scientists in their day-to-day work."

"You'll work with Python and learn to use machine learning to predict a variety of outcomes in computer vision, forecasting, clustering, and classification. For some perspective: I took approximately 4 months to finish the curriculum and found a new role with a substantial increase in compensation after just 22 days of searching. This is a great option for any student or professional with the motivation to do great work."

What We Look For


2 - 5 years of work experience in an analytical or technical role.

This could be as a data analyst, software engineer or applied scientist, among many other careers.


A quantitative academic degree.

At the minimum a B.S., however, a M.S. is required for the majority of jobs. Of course, a Ph.D. is the most sought-after qualification.


Experience with computer programming.

You do not need professional experience, however, you should have spent time on your own learning and building programs.


Live in or be willing to move to a major tech hub.

Approximately 80% of data science positions are located in the metropolitan areas of San Francisco and New York City. Another 15% are located in and around Boston, Chicago, Seattle, Washington DC, and Southern California (Los Angeles and San Diego). The remaining 5% are scattered throughout the country at large corporations, consulting firms and tech startups. If you are not in a large tech hub, you should be open to relocation in order to secure a data science role.

These are not strict criteria. We always evaluate each applicant individually and look out for motivated, non-traditional candidates. Check our student page to see the variety of backgrounds.

Featured Projects


Automate Updates and Enrichment of Client CRM

Details

Discrete Data Solutions provides software and data solutions to clients facing technology hurdles. In this instance, their client was a consulting firm with a large CRM, filled with thousands of outdated contacts. The client asked for a method to automate the updating of the contact information and addition of data from various social media sources.

In order to address this problem, Michael developed the following:

  • Several automated web scraping tools
  • Data processing pipeline that integrates data from multiple sources
  • A series of data matching ML models that leverage word vectorization and Levenshtein or Mallow distance as well as several other methods
  • Email format simulator based on the supervised learning models and trained with email addresses from others in the company and classified by when they joined the company

Tasks

  • Web Scraping
  • Data Cleaning and Processing
  • Record Linkage
  • Social Media Mining
  • Email Format Prediction

Examining Treatments and Healing Outcomes

Details

Parable reduces the cost & inconvenience of wound care through a platform that allows healthcare providers to better measure, monitor, and manage their wound patients. The platform facilitates care coordination and offers a mechanism to catch wound complications early. Specifically, Parable checks for clinical indicators of expected healing/development, captures a visual time lapse of the progression, and reminds patients (in ambulatory settings) about proper care instructions to ensure adherence.

For each case, a patient might check-in multiple times. We used data wrangling to capture the improvement of the wound between check-ins and later modeled that with the XGBoost implementation of gradient boosted trees to try to classify potential treatments either as an improvement or worsening of the wound, as well as to try to quantify what the improvement would be in an attempt to be able to recommend the best possible treatment for each case.

Tasks

  • Data Wrangling
  • Exploratory Data Analysis
  • Problem Formulation
  • Time Series Analysis
  • Classification

Product Taxonomy Classification for Retailers

Details

Havenly provides remote interior design solutions for users through their online platform. The design process includes product selection from the catalogs of partner retailers. Often the product classification provided is not consistent. This is due to many retailers maintaining their own hierarchy for product classification.

To address this problem, a process was developed for taxonomy classification using product descriptions provided by partner retailers. Natural language processing tools were used in conjunction with a support vector machine classifier to achieve an accuracy score of 0.99 on the test data set.

Tasks

  • Natural Language Processing
  • Taxonomy Classification

Industry Mentorship


If you need to learn data science fast, there’s no better way to do it than with personal advice and one-on-one project feedback.

Industry mentorship is for students to level up their skills as quickly and efficiently as possible. While all students will have access to feedback in the Slack channel and code reviews from a teaching assistant, industry mentorship will give you 30 one-on-one sessions with an experience data scientist, where you’ll screen share projects you’re working on and focus in on the topics that will personally help you the most. If you have never tried mentor-based learning, it adds an entirely new dimension to the experience.

What do you cover in these sessions? Let me give you some examples, based on past sessions:

  • "Here's a machine learning project I'm working on. Can you review it and give me pointers on what to change or improve?"
  • "Here is a data science problem I want to tackle. How you would approach it?"
  • "I'm a bit fuzzy on concept X, can you share practical use cases for it?"
  • "Let's talk more about scaling machine learning workflows / model evaluation / etc."

Anything that helps you become a better data scientist is fair game.

The 1-on-1 mentor sessions have:

  • No deadline: Now, next month, or whenever is best for you.
  • No format restrictions: You can structure the sessions however you want.
  • No off-limits topics: Ask you mentor anything that will help you improve your data science skills.

Do you wish you worked with an experienced data scientist who you could pepper with questions and get some real, in-depth feedback from? Think of this as your chance.
