How The Program Works

Here’s the play-by-play to get you from beginner/intermediate to advanced.
Overview

The course takes about 10 weeks to complete. It’s an in-depth study of one churn / binary classification problem that goes into every facet of how to solve it. Here’s the basic structure of DS4B 201-R.

Week 1: Getting ed

You begin with the problem overview and tool introduction covering how employee churn effects the organization, our toolbox to combat the problem, and code setup.

We introduce the Business Science Problem Framework, which is our step-by-step roadmap for data science project success.

The BSPF is used as guide as you progress through each chapter in the course.

Week 2: Business Understanding

You progress into sizing the problem.

You develop skills with dplyr and ggplot2, critical to exploring data. You are introduced to a new metaprogramming language called Tidy Eval for programming with dplyr.

You use Tidy Eval for the attrition code workflow, building a customizable plotting function to show executives which departments and job roles are costing the organization the most due to attrition.

Week 3: Data Understanding

The goal is to not waste time. You’ll learn two critical packages for exploring data and uncovering insights quickly.

First, you’ll investigate data by data type using the skimr package. You investigate continuous (numeric) and categorical (factor) data.

Next, you’ll investigate data relationships visually using GGally. You uncover key relationships between the target variable (attrition) and the features (e.g. tenure, pay, etc).

Week 4: Data Preparation

Next, you prepare the data for both humans and machines with the goal of making sure you have good features prior to moving into modeling. Again, the goal is to not waste time until we have fully understood the problem and have good features.

First, you use the tidyverse packages to wrangle data into a format that is readable by humans, creating a “human readable” processing pipeline.

Next, you use the recipes package to create a “machine readable” processing pipeline that is used to create a pre-modeling correlation analysis visualization.

The correlation analysis confirms we have good features and can proceed to modeling.

Weeks 5 & 6: H2O Modeling & Performance Analysis

Next, you learn H2O, a high performance modeling package. You spend two chapters with H2O.

In Chapter 4 (modeling), you learn the primary H2O functions for automated machine learning. You generate models including:

Generalized Linear Models (GLM)
Gradient Boosted Machines (GBM)
Random Forest (RF)
Deep Learning (DL)
Stacked Ensembles.

You create a visualization that examines the 30+ models you build.

In Chapter 5 (performance), you go in-depth into performance analysis. You learn about ROC Plot, Precision vs Recall, Gain & Lift Plots (which are for executive communication). You build the “ultimate model performance dashboard”.

Week 7: Explaining Black-Box Models

“The business won’t care how high your AUC is if you can’t explain your Machine Learning models. Explain those models.”

-Matt Dancho, Founder of Business Science

Now, you learn about LIME and how to perform local machine learning interpretability to explain complex models, showing which features contribute to attrition on a localized, employee level.

You’ll also have a cool challenge where you recreate the plots with a business-ready theme .

Weeks 8 & 9: Expected Value, Threshold Optimization, & Sensitivity Analysis

Now it’s time to link Machine Learning to Expected Financial Performance. You spend two chapters with on expected value, threshold optimization, and sensitivity analysis.

We with a basic case of making a “No Overtime” policy change. We then go through Expected Value Framework, a tool that enables targeting high-risk churners and accounts costs associated with false negatives / false positives.

We then teach how to optimize the threshold using purrr for iteration to maximize expected savings of a targeted policy. We then teach you Sensitivity Analysis again using purrr to show a heatmap that covers confidence ranges that you can explain to executives.

Week 10: Recommendation Algorithm Development

“To make progress, you need to make good decisions. Good decisions are systematic and data-driven.”

-Matt Dancho, Founder of Business Science

This is the culmination of your hard work. It’s time to apply critical thinking skills by developing a data-driven recommendation algorithm from scratch.

You will follow a 3-Step Process that shows you how to build a recommendation algorithm for any business problem.

“I have been going through books & MOOC’s to skill-up my data science game. DS4B 201-R is the first course that gives me a CLEAR FRAMEWORK to apply data science to Business Intelligence! It gives me the opportunity to bring data science to my organization and clearly articulate the business value proposition throughout the process. All that with the help of bleeding-edge open source tools (H2O, LIME, RStudio)”

– Renaud Liber, Business/Data Analyst – BI, Napoleon Games NV

“Business Science University is an excellent resource for learning data science. The DS4B 201-R course does a great job of teaching how to communicate a business problem, how to execute investigative thinking to solve the problem, and properly structuring code for collaboration and reusability. Most importantly, I took away a repeatable methodology and project structure that can be used to solve future business problems using data science. This was well worth the investment.”

Employee Attrition: A High-Impact Problem

Employee turnover (attrition) can be a $15M/YEAR COST to an organization that loses on average 200 high performing employees per year. Predicting turnover is at the forefront of Human Resources (HR) needs in many organizations. Further, HR departments typically have historical data on employees making this a perfect problem for DATA SCIENCE FOR BUSINESS.

Until now the mainstream approach has been to use logistic regression or survival curves to model employee attrition. However, with advancements in machine learning (ML), we can now get both better predictive performance and better explanations of what critical features are linked to employee attrition.

In Data Science For Business (DS4B 201-R), you’ll learn how to:

Use People Analytics (Human Resources) data to predict and explain employee turnover
Implement the Business Science Problem Framework and CRISP-DM to tackle any organizational data science problem
Perform automated machine learning with H2O
Explain complex, black-box machine learning models with LIME

How The 4-Course Virtual Workshop System Works

 

We use a hub-and-spokes model. DS4B 201-R (200-series course) is the hub that serves as the base for each extension (300-series courses). This maintains a consistent theme across multiple courses by using the same business problem while focusing on the tools that data scientist’s need to use in their day-to-day work.

Get immediately download DS4B 201-R – Data Science For Business With R

There are several advantages to the hub-and-spokes model:

 

It is focused on solving a problem
It simulates the real-world
Each course stands-alone so you can take what you are interested in
Courses can be combined, which exponentially magnifies your learning

DS4B 201-R is the first course in the 4-Course Virtual Workshop, and DS4B 201-R is what you get when you purchase this course. The release schedule for the others is TBA (to be announced). More information is coming!
Next Steps: Take The Rest Of The Virtual Workshop Courses!

A data scientist can never stop learning. When this happens, plateau sets in, which is exactly what you and your organization cannot afford! (This is why Business Science provides data science coaching as a service!)

Don’t plateau!

Continue with the rest of the Virtual Workshop to exponentially multiply your learning!

DS4B 301-R (COMING SOON): Building A Shiny App (Employee Smart Scorecard)

The most effective means of improving your organization is by helping others make data-driven decisions.

A Machine Learning-Powered Web Application is 100% the best way to do this. (Trust us, we’ve seen the change it makes in an organization.) Building a Machine Learning-Powered Web Application is easier than you think with Shiny!

You can further your capabilities by taking our integrated DS4B 301-R course, which implements our H2O model in a Shiny Web App for interactive employee attrition prevention recommendations. We call it the Employee Smart Scorecard!

DS4B 302-R (COMING SOON): Communicating With RMarkdown Reports

Executive communication makes or breaks a data science project. Further, data science can be extremely valuable in customer communication.

In DS4B 302-R, you’ll use RMarkdown to communicate the story through reports and presentations designed for your target audiences: executives (global decision makers), managers (local decision makers), and data science peers (reproducers / reviewers). Additionally, you’ll learn about parameterized Rmarkdown reports, which is perfect for automated reporting.

DS4B 303-R (COMING SOON): Building An R Package

Data scientists need to be able to create packages to simplify workflows and to keep the Data Science Team’s analyses consistent.

Build an R package, tidyattrition, in DS4B 303-R. The tidyattrition package follows the workflow developed in the Business Understanding phase. Learn to turn custom tidyeval functions such as assess_attrition(), calculate_attrition_cost(), and plot_attrition() into an R package that others can use!

Frequently Asked Questions

 

Who is this course for?
This course is for anyone with R programming experience seeking to apply data science for business (DS4B). It’s not for complete beginners! With that said, a basic understanding of R, dplyr, and ggplot2 will be sufficient to complete the course. Although the concepts are advanced, the hard stuff is explained such that a novice/intermediate learner will pick it up!
This course is part of a “4-Course Virtual Workshop”. What are the other courses?
We are currently working on 3 other courses. These are extensions of HR 201: – HR 301: Shiny App – We build this using the H2O and LIME model / output and the recommendation algorithm we build. – HR 302: Reporting / Communication – We go through communication and reporting for executives and the organization. We focus on Rmarkdown and also parameterized reports that can be deployed. – HR 303: R Package, tidyattrition – We create an R Package called tidyattrition that contains streamlined attrition workflow functions for creating the project directory, assessing attrition, and plotting attrition cost.
Does the current outline cover all 4-courses or just the HR 201 Course?
The current outline is just for the first. In the first course, we go through the BSPF problem framework, understand the business, understand the data, preprocess the data and perform a pre-modeling correlation analysis, develop H2O models, evaluate H2O modeling performance, use LIME to understand why the black-box model selects what it selects, develop recommendation logic, and evaluate the business value. That’s what DS4B HR 201 is about.
Is the price listed just for the first of four courses or for the entire four part workshop?
The prices listed is for the first course, which is the flagship (hub in hub-and-spokes). Other courses will be offered at an additional charge. These are all standalone courses so you can select which ones you want a la carte and you will receive all materials to complete that course independent of the rest. However, they all use the same data and theme for solving a singular problem, which is beneficial for practitioners in the real-world.
Should I take this course even though it deals with an Employee Attrition Problem, which is not in my domain?
Absolutely. The course uses a real-world example of an HR problem, which may not be specific to all Data Science For Business (DS4B) needs. However, the system and tools used are applicable to ANY BINARY CLASSIFICATION PROBLEM (for example, customer churn, fraud detection, any yes/no problem!). The real value is in the tools and techniques used – You will learn our process along with advanced tools!
Will this course be beneficial if I have a non-traditional background (e.g. Sales, Finance, Sociology, Marketing, Operations, Classical Music)?
Look, my background is non-traditional (mechanical engineering). If I can do it, you can do it. As long as you are (1) interested in data science, and (2) interested in applying it to business, then you are the right candidate. You should however take a basic course that teaches R, dplyr, and ggplot2 so you have the minimum skillset. Refer to the quiz: Test Your Baseline.
What will I learn beyond the basics?
You will learn a ton: H2O, LIME, recipes, and much much more! In addition to the course overview, the course has free-previews. Take a peek and see if you like the content.
I am finishing my degree. Will this course help me?
Yes. The course bridges the gap between academic data science and real-world data science in a business context. This makes it excellent, if not essential, to your ability to hit the ground running when you transition into an organization.
When does the course and finish?
The course s now and never ends! It is a completely self-paced online course – you decide when you and when you finish.
Are these courses self-paced, asynchronous?
All courses are completely self-paced. You can take them on your own schedule. The content uses pre-recorded video, and we will handle comments as we receive. The courses can be taken asynchronously. However, most will want to take HR 201 first before proceeding into the 300-series courses since this provides a foundation of the business problem and exposure to H20 and LIME.
How long do I have access to the course?
How does lifetime access sound? After enrolling, you have unlimited access to this course for as long as you like – across any and all devices you own.
Will the course continue to be updated with new content?
Yes – I have a number of new sections planned, and I will be actively improving to make sure the content is perfect! Your membership includes lifetime access as the course evolves.
What is the geographic availability for the course? Will it work outside US?
Yes – The course can be taken from virtually any geographic location that is permitted to trade with the US. This should cover 99.9% of the world population!
I love the course, but I can’t afford it. What options do I have?
The value the course will deliver is exponentially more than its price. You have two options. First, your employer may offer education assistance. This is highly recommended because the education will ultimately benefit them… financially! (See the $15M/year problem lecture). Second, if self-funded, view it as an investment. What you are getting will help you get a job, develop a portfolio of experience using cutting-edge tools and processes, and manage a data science project the way we do!
What if I am unhappy with the course?
We would never want you to be unhappy! If you are unsatisfied with your purchase, contact us in the first 30 days and we will give you a full refund. Signup is risk-free!
Do you offer a payment plan?
Yes – We have a 3-payment monthly plan at a slightly higher rate. This option spreads the payments over three months.
