Code for Workshop: Introduction to Machine Learning with R

These are the slides from my workshop: Introduction to Machine Learning with R which I gave at the University of Heidelberg, Germany on June 28th 2018. The entire code accompanying the workshop can be found below the video. The workshop covered the basics of machine learning. With an example dataset I went through a standard machine learning workflow in R...

Addendum: Text-to-Speech with the googleLanguageR package

June 28, 2018
By

After posting my short blog post about Text-to-speech with R, I got two very useful tips. One was to use the googleLanguageR package, which uses the Google Cloud Text-to-Speech API. And indeed, it was very easy to use and the resulting audio sounded much better than what I tried before! Here’s a short example of how to use the package for...

Text-to-speech with R

June 26, 2018
By

Computers started talking to us! They do this with so called Text-to-Speech (TTS) systems. With neural nets, deep learning and lots of training data, these systems have gotten a whole lot better in recent years. In some cases, they are so good that you can’t distinguish between human and machine voice. In one of our recent codecentric.AI videos, we compared...

Explaining Keras image classification models with lime

Last week I published a blog post about how easy it is to train image classification models with Keras. What I did not show in that post was how to use the model for making predictions. This, I will do here. But predictions alone are boring, so I’m adding explanations for the predictions using the lime package. I have already written...

It’s that easy! Image classification with keras in roughly 100 lines of code.

I’ve been using keras and TensorFlow for a while now - and love its simplicity and straight-forward way to modeling. As part of the latest update to my Workshop about deep learning with R and keras I’ve added a new example analysis: Building an image classifier to differentiate different types of fruits And I was (again) suprised how fast and easy...
