This little helper counts missing values within a vector.
This little helper prints a progress bar into the console for loops.
The aim of this little helper is to visualise the connections between R functions within a project as a flowchart.
This little helper splits a given string into smaller parts with a fixed length.
This little helper combines multiple ggplots into one plot. This is a function taken from the R cookbook.
This little helper removes missing values from a list.
This little helper checks a given folder path for existence and creates it if needed.
The first time we at STATWORX are organizing a workshop for anyone who wants to learn more about data and graphics. Our “Data Visualization in R and ggplot2” workshop is designed for R-beginners and provides the perfect mixture between theory and practice. The workshop will be held at Mindspace in Munich. Participants achieve first insights into the concepts of data …
In a recent project at STATWORX, I’ve developed a large scale deep learning application for image classification using Keras and Tensorflow. After developing the model, we needed to deploy it in a quite complex pipeline of data acquisition and preparation routines in a cloud environment. We decided to deploy the model on a prediction server that exposes the model through …
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. In any case, understanding these …
