    New Course Content: DS4B 201 Chapter 7, The Expected Value Framework For Modeling Churn With H2O
    Written by Matt Dancho on July 16, 2018

    I’m pleased to announce that we released brand new content for our flagship course, Data Science For Business (DS4B 201). Over the course of 10 weeks, the DS4B 201 course teaches students and end-to-end data science project solving Employee Churn with R, H2O, & LIME. The latest content is focused on transitioning from modeling Employee Churn with H2O and LIME to evaluating our binary classification model using Return-On-Investment (ROI), thus delivering business value. We do this through application of a special tool called the Expected Value Framework. Let’s learn about the new course content available now in DS4B 201, Chapter 7, which covers the Expected Value Framework for modeling churn with H2O!

    Data Science For Business: 3 Reasons You Need To Learn The Expected Value Framework
    Written by Matt Dancho on July 11, 2018

    One of the most difficult and most critical parts of implementing data science in business is quantifying the return-on-investment or ROI. As a data scientist in an organization, it’s of chief importance to show the value that your improvements bring. In this article, we highlight three reasons you need to learn the Expected Value Framework, a framework that connects the machine learning classification model to ROI. Further, we’ll point you to a new video we released on the Expected Value Framework: Modeling Employee Churn With H2O that was recently taught as part of our flagship course: Data Science For Business (DS4B 201). The video serves as an overview of the steps involved in calculating ROI from reducing employee churn with H2O, tying the key H2O functions to the process. Last, we’ll go over some Expected Value Framework FAQ’s that are commonly asked in relation to applying Expected Value to machine learning classification problems in business.

    Time Series Deep Learning, Part 2: Predicting Sunspot Frequency with Keras LSTM In R
    Written by Sigrid Keydana, Matt Dancho on July 1, 2018

    One of the ways Deep Learning can be used in business is to improve the accuracy of time series forecasts (prediction). We recently showed how a Long Short Term Memory (LSTM) Models developed with the Keras library in R could be used to take advantage of autocorrelation to predict the next 10 years of monthly Sunspots (a solar phenomenon that’s tracked by NASA). In this article, we teamed up with RStudio to take another look at the Sunspots data set, this time implementing some really advanced Deep Learning functionality available with TensorFlow for R. Sigrid Keydana, TF Developer Advocate at RStudio, put together an amazing Deep Learning tutorial using keras for implementing Keras in R and tfruns, a suite of tools for trackingtracking, visualizing, and managing TensorFlow training runs and experiments from R. Sounds amazing, right? It is! Let’s get started with this Deep Learning Tutorial!

    Data Science For Business Tutorial: Using Machine Learning With LIME To Understand Employee Churn
    Written by Brad Boehmke on June 25, 2018

    Data science tools are getting better and better, which is improving the predictive performance of machine learning models in business. With new, high-performance tools like, H2O for automated machine learning and Keras for deep learning, the performance of models are increasing tremendously. There’s one catch: Complex models are unexplainable… that is until LIME came along! LIME, which stands for Local Interpretable Model-agnostic Explanations, has opened the doors to black-box (complex, high-performance, but unexplainable) models in business applications! Explanations are MORE CRITICAL to the business than PERFORMANCE. Think about it. What good is a high performance model that predicts employee attrition if we can’t tell what features are causing people to quit? We need explanations to improve business decision making. Not just performance.

    How To Successfully Manage A Data Science Project For Businesses: The Business Science Problem Framework
    Written by Matt Dancho on June 19, 2018

    Data Scientists want to run successful projects. However, the sad fact is that most data science projects in organizations fail. It’s not because of lack of skill or knowledge. Data science projects need a clear and effective plan of attack to be successful. As data scientists, we study a wide array of tools: advanced algorithms, knowledge of statistics, and even programming skills. However, if you’re like us, you’ve had to learn how to successfully manage a project through trial and error. Fortunately, we’ve learned a lot over the past several years working with clients, and we’ve integrated the best resources into one streamlined framework to make your life easier: The Business Science Project Framework! In this article, we’ll cover the basics showing you how the BSPF helps as a guide for successful data science projects following a Customer Churn Problem example. Download the BPSF for FREE here.
