This year, the SpinningBytes team participated in the VarDial competition, where we achieved second place in the German Dialect Identification shared task. The task’s goal was to identify, which region the speaker of a given sentence is from, based on the dialect he or she speaks. Dialect identification is an important NLP task; for instance, it can be used for automatic processing in a speech-to-text context, where identifying dialects enables to load a specialized model. In this blog post, we do a step by step walkthrough how to create the model in Python, while comparing it to previous years’ approaches.

OpenAI Gym environment for Modelica models

By Gabriel Eyyi (ZHAW)

In this blog post I will show how to combine dynamic models from Modelica with reinforcement learning.

As part of one of my master projects a software environment was developed to examine reinforcement learning algorithms on existing dynamic models from Modelica in order to solve control tasks. Modelica is a non-proprietary, object-oriented, equation based language to conveniently model complex physical systems [1].

The result is the Python library Dymola Reinforcement Learning (dymrl) which allows you to explore reinforcement learning algorithms for dynamical systems.

The code of this project can be found at github.

Deep learning for lazybones

By Oliver Dürr (ZHAW)

Reposted from http://oduerr.github.io/blog/2016/04/06/Deep-Learning_for_lazybones

In this blog I explore the possibility to use a trained CNN on one image dataset (ILSVRC) as feature extractor for another image dataset (CIFAR-10). The code using TensorFlow can be found at github. Continue reading
