The ROC (receiver operating characteristic) curve visually depicts the ability of a measure or classification model to distinguish two groups. The area under the ROC (AUC), quantifies the extent of that ability. My goal here is to describe as simply as possible a process that serves as a foundation for the ... Read More

Feed: R-bloggers. Author: R on Sastibe's Data Science Blog. Recently, I was tasked with a straightforward question: “In an A/B test setting, how many samples do I have to collect in order to obtain significant results?” As ususal in statistics, the answer is not quite as straightforward as the question, and it depends quite a bit on the framework. In this case, the A/B test was supposed to test whether the effect of a treatment on the success rate p had the assumed size e. The value of the success rate had to be estimated in both test and control ... Read More

We’ve seen on a previous post that one of the main differences between classic ML and Causal Inference is the additional step of using the correct adjustment set for the predictor features. In order to find the correct adjustment set we need a DAG that represents the relationships ... Read More

Feed: R-bloggers. Author: Przemyslaw Biecek. Version 0.2.1 of the modelStudio package reached CRAN this week. Let me shortly overview coolest new features (list of all changes). Short reminder: The modelStudio package creates an interactive serverless D3.js dashboard for exploration of predictive models, which is based on principles of Explanatory Model Analysis. With modelStudio interface, one can juxtapose instance-level model explanations (Break Down, Shapley values and Ceteris Paribus profiles), dataset-level model explanations (Partial Dependence Plots, Feature Importance, Accumulated Local Effects Plot) and data exploration plots (histogram and scatterplots). Examples below use a GBM model trained on the kaggle FIFA 19 dataset ... Read More

Feed: R-bloggers. Author: Learning Machines. We already covered the so-called Accuracy-Interpretability Trade-Off which states that oftentimes the more accurate the results of an AI are the harder it is to interpret how it arrived at its conclusions (see also: Learning Data Science: Predicting Income Brackets). This is especially true for Neural Networks: while often delivering outstanding results, they are basically black boxes and notoriously hard to interpret (see also: Understanding the Magic of Neural Networks). There is a new hot area of research to make black-box models interpretable, called Explainable Artificial Intelligence (XAI), if you want to gain some intuition ... Read More
