Model Regularization – The Bayesian Way

Thomas Alcock Blog, Data Science

Are you confused by Bayesian statistics? If you understand Ridge regression, one of the most common Bayesian models is within your reach! This post gives a brief intro to Bayesian thinking and shows you just how similar Ridge regression is to Bayesian linear regression by walking you through the math and exploring how coefficient estimates from both models compare.

Tuning Random Forest on Time Series Data

Manuel Tilgner Blog, Data Science

Training random forests on time series is one thing, but tuning them? It’s not like you can just apply cross validation and be done with it. Or can you? This post forms part two our mini-series “Time Series Forecasting with Random Forest”. Find out how you can tune the hyperparameters of the random forest algorithm when dealing with time series data. The answers might surprise you!

Coding Gradient boosted machines in 100 lines of R code

André Bleier Blog, Data Science

Motivation There are dozens of machine learning algorithms out there. It is impossible to learn all their mechanics, however, many algorithms sprout from the most established algorithms, e.g. ordinary least squares, gradient boosting, support vector machines, tree-based algorithms and neural networks. At STATWORX we discuss algorithms daily to evaluate their usefulness for a specific project or problem. In any case, …

A Performance Benchmark of Different AutoML Frameworks

Fabian Müller Blog, Data Science

In a recent blog post our CEO Sebastian Heinz wrote about Google’s newest stroke of genius – AutoML Vision. A cloud service „that is able to build deep learning models for image recognition completely fully automated and from scratch„. AutoML Vision is part of the current trend towards the automation of machine learning tasks. This trend started with automation of …
