How we use emojis

Jakob Gepp Blog

Once upon a time, we at STATWORX used Slack just as a messenger, but than everything changed when emojis came… Since then, we use them for all kinds of purposes. For example we take polls with them to see were we will eat lunch or we capture unforgettable moments by creating new emojis. The possibilities are limitless! But since we …

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 …

Custom themes in ggplot2

Lea Waniek Blog, Data Science, Statistik

In the last post of this series of the STATWORX Blog, we explored ggplot2's themes, which control the display of all non-data components of a plot. Ggplot comes with several inbuilt themes that can be easily applied to any plot. However, one can tweak these out-of-the-box styles using the theme() function. We did this last time. Furthermore, one also can …

CodeR: an LSTM that writes R Code

Tobias Krabel Blog, Data Science

Everybody talks about them, many people know how to use them, few people understand them: Long Short-Term Memory Neural Networks (LSTM). At STATWORX, with the beginning of the hype around AI and projects with large amounts of data, we also started using this powerful tool to solve business problems. In short, an LSTM is a special type of recurrent neural …

Using themes in ggplot2

Lea Waniek Blog

As noted elsewhere, sometimes beauty matters. A plot that’s pleasing to the eye will be considered more gladly, and thus might be understood more thoroughly. Also, since we at STATWORX oftentimes need to subsume and communicate our results, we have come to appreciate how a nice plot can upgrade any presentation. So how make a plot look good? How make …

Benchmarking Feature Selection Algorithms with Xy()

André Bleier Blog, Data Science

Feature Selection Feature Selection is one of the most interesting fields in machine learning in my opinion. It is a boundary point of two different perspectives on machine learning – performance and inference. From a performance point of view, feature selection is typically used to increase the model performance or to reduce the complexity of the problem in order to …

Using Machine Learning for Causal Inference

Markus Berroth Blog, Data Science

Machine Learning (ML) is still an underdog in the field of economics. However, it gets more and more recognition in the recent years. One reason for being an underdog is, that in economics and other social sciences one is not only interested in predicting but also in making causal inference. Thus many "off-the-shelf" ML algorithms are solving a fundamentally different …
