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 …

Learning Images with Keras

Lukas Strömsdörfer Blog, Data Science

Introduction Teaching machines to handle image data is probably one of the most exciting tasks in our daily routine at STATWORX. Computer vision in general is a path to many possibilities some would consider intruiging. Besides learning images, computer vision algorithms also enable machines to learn any kind of video sequenced data. With autonomous driving on the line, learning images …

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 …

QlikView vs Qlik Sense

Unterschiede zwischen Qlik Sense und QlikView

Markus Berroth Blog, Data Science

Daten-Visualisierung und -Verständnis sind wichtige Faktoren bei der Durchführung eines Data Science Projekts. Eine visuelle Exploration der Daten unterstützt den Data Scientist beim Verständnis der Daten und liefert häufig wichtige Hinweise über Datenqualität und deren Besonderheiten. Bei STATWORX wenden wir im Bereich Datenvisualsierung eine Vielzahl von unterschiedlichen Tools und Technologien an, wie z.B. Tableau, Qlik, R Shiny oder D3. Seit …

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 …

A performance benchmark of Google AutoML Vision using Fashion-MNIST

Sebastian Heinz Blog, Data Science

Google AutoML Vision is a state-of-the-art cloud service from Google that is able to build deep learning models for image recognition completely fully automated and from scratch. In this post, Google AutoML Vision is used to build an image classification model on the Zalando Fashion-MNIST dataset, a recent variant of the classical MNIST dataset, which is considered to be more …

Data Science in Python – Der Einstieg in Machine Learning mit Scikit-Learn

Moritz Gnisia Blog, Data Science

In unseren bisherigen Artikeln zu Data Science in Python haben wir uns mit der grundlegenden Syntax, Datenstrukturen, Arrays, der Datenvisualisierung und Manipulation/Selektion auseinander gesetzt. Was jetzt noch für den Einstieg fehlt, ist die Möglichkeit Modelle auf die Daten anzuwenden, um so zum einen Muster in diese zu erkennen und zum anderen Prädiktionen abzuleiten. Die Vielfalt an implementierten Modellen in Python …

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 …
