OriginLab’s Graph Gallery: A blast from the past

OriginLab’s Graph Gallery: A blast from the past

Continuing my recent line of posts on data visualization resources, I found another repository in my inbox: OriginLab’s GraphGallery!

If I’m being honest, I would personally advice you to look at the dataviz project instead, if you haven’t heard of that one yet.

However, OriginLab might win in terms of sentiment. It has this nostalgic look of the ’90s, and apparently people really used it during that time. Nevertheless, despite looking old, the repo seems to be quite extensive, with nearly 400 different types of data visualizations:

Quantity isn’t everything though, as some of the 400 entries are disgustingly horrible:

There’s so much wrong with this graph…

What I do like about this OriginLab repo is that it has an option to sort its contents using a random order. This really facilitates discovery of new pearls:

Thanks to Maarten Lambrechts for sharing this resource on twitter a while back!

Tensorflow for R Gallery

Tensorflow for R Gallery

Tensorflow is a open-source machine learning (ML) framework. It’s primarily used to build neural networks, and thus very often used to conduct so-called deep learning through multi-layered neural nets. 

Although there are other ML frameworks — such as Caffe or Torch — Tensorflow is particularly famous because it was developed by researchers of Google’s Brain Lab. There are widespread debates on which framework is best, nonetheless, Tensorflow does a pretty good job on marketing itself.

I primarily work in the programming language R, and have written before about how to start with deep learning in R using Keras — an user-friendly API built on top of, among others, Tensorflow. Now, it has become even easier to learn how to implement the power of Tensorflow in R, for RStudio has compiled a gallery of featured posts on Tensorflow implementations in R. It features a variety of applications related to collaborative filtering, image recognition, audio classification, times series forecasting, and fraud detection, all using Keras and TensorFlow. I highly recommend you check it out if you want to learn more about deep learning in R.
