DS4B 102-R: Shiny Web Applications (Intermediate)

Build a predictive web application using Shiny, Flexdashboard, and XGBoost

Build Web Apps with Machine Learning

The web application you learn how to build uses data science to predict new product prices!

Predictive Web Applications Productionalize Data Science

A data scientist generates organizational value by building web apps that take machine learning models into production.
Here's an example of a predictive web application that you build in this course.
New Product Prediction Application (created in this course)
This web application empowers business people to make data-driven decisions by more consistently pricing products. The application incorporates:
  • Shiny – A web application framework with UI components that are reactive to user input.
  • Flexdashboard – A dashboarding framework that is built on top of RMarkdown.
  • parsnip and XGBoost – Machine learning models used to predict product prices.
Most importantly, business people can use the application to improve the consistency of new product prices based on an existing product portfolio thanks to the power of Machine Learning!

Your Organization Cares About Branding

So give it to them. Learn how to customize the appearance of your application to match your organizations branding.

Final Project

You will build a Sales Dashboard that:
  • Uses XGBoost to Predict Sales Demand by Customers & Product Categories.
  • Toggles between Light and Dark Themes – Customized by You and your theme-building skills!
  • Controls flow using Reactive Programming
  • Will be distributed via Shinyapps.io
Final Project
Dark Theme

This course is designed for…

  • Beginner data scientists that have completed the DS4B 101-R course and want to build predictive web applications
  • Intermediate data scientists familiar with R but want to learn Shiny and Flexdashboard

3-Step System

Follow a 3-step learning path:
  1. Build your knowledge of core concepts with a Sales Dashboard
  2. Extend your knowledge of Machine Learning and advanced techniques into Price Prediction Application
  3. Customize the end product with theme and logos

Course Roadmap

Experience the innovative 3-Step System!

Step 1: You'll start by creating a Sales Dashboard

Creating a Sales Dashboard exposes you to reactive programming. You will apply complex rules to control how your application functions when users interact with the app.
You gain experience using:
  • Shiny
  • Geographic Data
  • Time Series Data
  • Interactive Plots
  • Reactive Programming
  • Observing Events & Controlling Flow

Step 2: Next, You Create A Predictive Web Application

You will build a new application that integrates Machine Learning (XGBoost) along with a more complex interactive visualization.
You learn how to:
  • Integrate machine learning (parsnip and XGBoost) into a Web App
  • Modularize code into functions
  • Create advanced interactive charts

Step 3: You finish by Customizing Your Web Application

Your company's brand appearance is important. Make an app theme that is consistent with the look and feel of your organization's branding.

Create Your Own Theme Using HTML & CSS

Use Google's Chrome Inspector

You will:
  • Learn to use Google Inspector for inspecting web pages
  • Add logos
  • Adjust the theme with CSS

Business Objective: Use Data Science to More Consistently Price Products

The Business Problem:
Businesses can lose customer confidence and profitability if products are inconsistently priced.
The Solution:
This web application solves the inconsistent pricing problem by using predictive analytics to generate new product prices based on existing products.
The application is easy to use, and best of all, an app like this generates business value for your organization!
