Model Prediction Accuracy Versus Interpretation in Machine Learning

Last Updated on August 15, 2020 In their book Applied Predictive Modeling, Kuhn and Johnson comment early on the trade-off of model prediction accuracy versus model interpretation. For a given problem, it is critical to have a clear idea of the which is a priority, accuracy or explainability so that this trade-off can be made explicitly rather than implicitly. In this post you will discover and consider this important trade-off. Model Accuracy vs ExplainabilityPhoto by Donald Hobern, some rights reserved […]

Improve Model Accuracy with Data Pre-Processing

Last Updated on August 15, 2020 Data preparation can make or break the predictive ability of your model. In Chapter 3 of their book Applied Predictive Modeling, Kuhn and Johnson introduce the process of data preparation. They refer to it as the addition, deletion or transformation of training set data. In this post you will discover the data pre-process steps that you can use to improve the predictive ability of your models. Kick-start your project with my new book Data […]

Clever Application Of A Predictive Model

Last Updated on August 15, 2020 What if you could use a predictive model to find new combinations of attributes that do not exist in the data but could be valuable. In Chapter 10 of Applied Predictive Modeling, Kuhn and Johnson provide a case study that does just this. It’s a fascinating and creative example of how to use a predictive model. In this post we will discover this less obvious use of a predictive model and the types of […]

Going Beyond Predictions

Last Updated on June 7, 2016 The predictions you make with a predictive model do not matter, it is the use of those predictions that matters. Jeremy Howard was the President and Chief Scientist of Kaggle, the competitive machine learning platform. In 2012 he presented at the O’reilly Strata conference on what he called the Drivetrain Approach for building “data products” that go beyond just predictions. In this post you will discover Howard’s Drivetrain Approach and how you can use […]
