Enroll

Prerequisites

Students should have some experience with Python and have some familiarity with basic statistical and linear algebraic concepts such as mean, median, mode, standard deviation, correlation, and the difference between a vector and a matrix. In Python, it will be helpful to know basic data structures such as lists, tuples, and dictionaries, and what distinguishes them (that is when they should be used). Students should skip the pre-work if they can accomplish all of the following:

Write a program in Python that finds the most frequently occurring word in a given sentence.
Explain the difference between correlation and covariance, and why the difference between the two terms matters.
Multiply two small matrices together (e.g. 3X2 and 2X4 matrices).

Otherwise, students should complete the following pre-work (approximately 8 hours) before the first day of class:

Exercises 1-7, 13, 18-21, 27-35, 38,39 of Learn Python The Hard Way. (If the link is outdated, you can access the main website here.)
Videos 1-6 of Linear Algebra review from Andrew Ng’s Machine Learning course (labeled as: III. Linear Algebra Review (Week 1, Optional).
The exercises in Chapters 2 and 3 of OpenIntro Statistics. (This book is free, but there is a suggested donation. Feel free to donate an amount or set it to zero.)

Students must have a Github account to get access to the content. Sign-up for an account on their site is free, fast and easy.

Course Structure & Syllabus

Week 1

CS/Statistics/Linear Algebra Short Course

We start with the basics. For CS, we briefly cover basic data structures/types, program control flow, and syntax in Python. For statistics, we go over basic probability and probability distributions, along with general properties of some common distributions. For linear algebra, we cover matrices, vectors, and some of their properties and how to use them in Python.

Week 2

Exploratory Data Analysis and Visualization

We spend a considerable amount of time using the Pandas Python package to attack a dataset we’ve never seen before, uncovering some useful information from it. At this point, students decide on a course project that would benefit from the data-scientific approach. The project must involve public (freely-accessible and usable) data and must answer an interesting question, or collection of questions, about that data. (Several resources of free data will be provided.)

Week 3

Data Modeling: Supervised/Unsupervised Learning and Model Evaluation

We learn about the two basic kinds of statistical models, which have classically been used for prediction (supervised learning): Linear Regression and Logistic Regression. We also look at clustering using K-Means, one of the ways you can glean information from unlabeled data.

Week 4

Data Modeling: Feature Selection, Engineering, and Data Pipelines

We switch gears from talking about algorithms to talk about features. What are they? How do we engineer them? And what can be done (Principal Component Analysis/Independent Component Analysis, regularization) to create and use them given the data at hand? We also cover how to construct complete data pipelines, going from data ingestion and preprocessing to model construction and evaluation.

Week 5

Data Modeling: Advanced Supervised/Unsupervised Learning

We delve into more advanced supervised learning approaches and get a feel for linear support vector machines, decision trees, and random forest models for regression and classification. We also explore DBSCAN, an additional unsupervised learning approach.

Week 6

Data Modeling: Advanced Model Evaluation and Data Pipelines | Presentations

We explore more sophisticated model evaluation approaches (cross-validation and bootstrapping) with the goal of understanding how we can make our models as generalizable as possible. Students complete data science projects and share learnings and discoveries.

FAQs

For this course, do I need to know Python. If so, how much Python do I need to know to take this course? What version of python is used?

Python is a requirement for the course. In Python, it will be helpful to know basic data structures such as lists, tuples, and dictionaries, and what distinguishes them (that is, when they should be used). Python v3 is currently used in the course.
How much do part-time courses at Metis cost?

Live online bootcamp prep courses cost $750.
Can I apply tuition from my part-time course to the bootcamp?

Yes! Part-time alumni can apply the amount of tuition paid for one part-time course toward enrollment in an upcoming bootcamp upon admittance.
Do I receive pass/fail grades on completion of a part-time course?

No, you receive a certificate of completion stating that you completed up to 36 hours of the course. Hours vary by course.
How much homework is required outside of class time?

While there is no official homework, you can expect to spend a minimum of 3 hours per week reviewing material or working on projects. The non-class time spent will depend on your background and the course itself. Each instructor will address this on the first day of class, and there will be lab/office hours outside of class during which students and the instructor can collaborate.
Will we work on any projects? What are some examples of projects students have completed in the past?

Students work on a final project in this course. Here is an example project, which analyzes the likelihood of pets getting adopted in shelters, and here’s another example about predicting star ratings on Yelp.
Do I get career support if I take a part-time course?

No. We do not offer career support for students of these courses like we do for our bootcamp students, but you will gain access to our alumni community network of 1000+ data scientists. Networking events and job opportunities are posted on a regular basis in this active digital community.
Who are the instructors for the part-time courses? Are they bootcamp instructors? What are their backgrounds?

Our part-time course instructors come to teach at Metis from industry and are not bootcamp instructors. Please visit the respective course pages for specific information on each instructor’s background and current jobs.
How often do Metis part-time courses meet?

Our part-time courses typically run two nights per week over the course of 6 weeks, totaling 36 hours of instruction, but this can vary. Please see the full schedule here for the most up-to-date information. We consistently add new courses, so be sure to check back routinely.
Does Metis offer any part-time courses online?

Yes, we currently offer a rotating selection of our part-time bootcamp prep courses in a Live Online format, meaning once registered, you can login from anywhere to learn.
What are the benefits of taking a course in a Live Online format?

The beauty of the Live Online format is that you’re taught by our industry-leading instructors live, but you can attend class sessions from literally anywhere you have an internet connection. Unlike some other online course options out there, which might consist of pre-recorded lectures, our courses allow for interaction with the instructor, teaching assistants, and other students – and because these are on a set schedule, you’ll be held accountable to actually attend, do the work, and learn the material (which is what you’re really here for anyway!).
I took a Metis part-time course and now want to apply for the bootcamp. Does that give me a competitive edge?

It does not, simply because we evaluate each and every bootcamp applicant the same way in order to ensure fairness. However, if accepted into the bootcamp, you do have the advantage of applying the amount of one part-time course tuition toward the bootcamp tuition, so you essentially got your part-time course for free.
How will I receive access to the curriculum?

The curriculum will be provided via Github; therefore, you must register a Github account. Sign-up for an account on their site is free, fast and easy. Github is a web-based hosting service for version control using Git.
