Meetup #1: Microsoft Data Science Azure Machine Learning Workshop

Microsoft Data Science Azure Machine Learning Workshop Lab  Setup and Instruction Guide In this first Microsoft Data Science meetup, hosted by Infi and with guest speaker Jeroen ter Heerdt from Microsoft, we also organized a workshop to get the basics of machine learning on the Azure platform. Overview In this […]


Human Resources Analytics – Why employees are leaving

In this blog about human resources analytics, we are building a model to predict whether an employee will leave or not, and we will also try to find out why they leave, according to the data. We will use a simulated dataset from Kaggle, which can be found here: https://www.kaggle.com/ludobenistant/hr-analytics […]

Optimizing prediction models on Azure

Optimizing prediction models on Azure – pruning the trees 9

This is a simple example about optimizing prediction models on Azure. In this case we will use a Boosted Decision Tree model. We will show you how you can use the Permutation Feature Performance module to prune your trees. We start with the Student Performance Classifier from a previous blog. We […]


Human Activity Classifier Azure Machine Learning

How to build a Human Activity Classifier with Azure Machine Learning

This blog explains how to build a Human Activity Classifier with Azure Machine Learning. This classifier predicts somebody’s activity class based on the use of wearable sensors. The complete experiment can be downloaded from the Azure Machine Learning Gallery. Description of the Human Activity Classifier This classifier predicts somebody’s activity class (sitting, […]


Azure Machine Learning – Qualitative Activity Recognition of Weight Lifting Exercises

This blog is about building a classifier on the Azure Machine Learning platform for qualitative activity recognition of weight lifting exercises. This classifier predicts if an exercise has been done correctly (class A). We will use data from accelerometers on the belt, forearm, arm, and dumbell of 6 participants. They were […]

How to build a Student Performance Classifier with Azure Machine Learning 1

This blog explains how to build a Student Performance Classifier with Azure Machine Learning. This classifier predicts if a student will pass or fail Mathematics. The complete experiment can be downloaded from the Azure Machine Learning Gallery. Description of the Student Performance Classifier This classifier predicts a student’s performance for Mathematics (fail or […]


Azure Machine Learning: how to easily improve your model 1

Improving your Azure Machine Learning model In this example we start with a sample experiment from the Microsoft Azure Machine Learning Gallery: Regression: Demand estimation. In this example there are four models built, and compared, based the newly created features. We will explore whether standard operations could improve these samples models, […]
