About This Free Course
Learn machine learning by building real projects with retail data. This course focuses on understanding ML concepts, building models, and calculating business impact. We don't cover deployment or production systems. Instead, you'll master the skills that come first: knowing which models to build, how to evaluate them, and how to prove they're worth building.
This course is designed for free ai for business analysts business analyst ai fast track course, product managers, and career changers who already have a basic grasp of Python. To ensure you are ready for the projects, we start with "Getting Runway Ready" (a specialized onboarding section that includes a 10-part Python Refresher series). These bite-sized videos bridge the gap between general Python knowledge and the specific data manipulation skills required for high-level retail analytics.
You'll work with real transaction and product data from Google BigQuery's public "TheLook" ecommerce dataset. You will learn how to access this global data warehouse directly. This is a professional skill that allows you to find and query data in any industry.
I chose retail and fashion data for three reasons: the problems are universal, the data is visual, and the business impact is easy to calculate. Once you understand how ML solves retail problems, you can adapt these techniques to any domain, including healthcare or finance.
You'll build three complete machine learning projects:
Product Classification: Automatically categorize thousands of products using classification algorithms.
Demand Forecasting: Use the Prophet library to predict sales trends and prevent stockouts.
Customer Segmentation: Use K-means clustering and RFM analysis to personalize marketing.
Each project walks you through the complete process: understanding the business problem, preparing data, building the model, and calculating the dollar value of your work.
All tools are free. You’ll use Google BigQuery to access "The Look" public dataset and Google Colab to run your code in the browser. I provide curated datasets and complete Python notebooks for every project so you can focus on the analysis, not the data cleaning.
Each project includes professional documentation templates (executive summaries and ROI calculators) giving you three complete case studies for your professional portfolio.
This course is not for complete programming beginners. It is for those who know the basics of Python and want to apply those skills to solve real-world business problems with Machine Learning.
This course is created and taught independently by Nneka J. Penniston. While the instructor teaches as Adjunct Faculty at Columbia University, this course is not affiliated with, endorsed by, or sponsored by Columbia University or NYU Stern School of Business.
Who Should Take This Course
"Code Fashionably: Retail Machine Learning for Business" is aimed at people who want a practical, structured introduction to udemy without paying full price for it. It's a solid fit if you're starting out in udemy and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 4.5/5 rating on Udemy. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a udemy course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether udemy is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
