Ok, this is not Data Science. This is just for fun. I have to admit, I tend to mix up things. Here I am mixing up the German class I am taking with one of the visualizations that I prefer, the wordcloud. Not because it conveys a message about data, in this case is just …
I was using my own article “A R kernel in IPython notebook: Jupyter“, to install both Jupyter and the IRKernel on a small ASUS Eee PC Seashell 12” laptop that I use when we are on holidays. This runs Kubuntu, as most of the PCs in my household. Unfortunately the instructions I provided in July …
After having become familiar with Ipython and its notebook mode (thanks to the MOOC Python pour les Scientifiques) , which allows to use the python language in an interactive and online way through a web browser, the familiarization with the R language through a more traditional (even if advanced) IDE like RStudio looks honestly like …
This article has the objective of scraping a web site with the purpose of generating a wordcloud out of its text. The wordcould visualization of text is something that is becoming more and more popular, and you find it more and more also in common TV shows, where some presenters have had the idea to …
Matplotlib is a powerful library, and it can be combined with a number of other powerful Python features. Here I would like to play with the cartopy geographical library, using Ipython notebook and keeping all the images generated inline. I am going to use two open data sources, one is the MapquestOSM, the other is …
This is the second of the series on the python libraries. I do not know how much I will write but remember, these are only learning notes. The inspiration came this time from the ever-present stackoverflow.com, with an article on making matplotlib graphs look like R by deafult. I am learning here, so for the …
This is the first of a series of articles dedicated to the python’s libraries for scientific use. The first library I would like to introduce is strictly related to my previous post about TF-IDF. In the vast world of python there is a library, gensim, which contains a series of tools to implement a tfidf …
Today I will tell you a bit about my trip to the world of Python for scientific usage, and about two of the libraries that I found more amazing in general: Mathplotlib and Pandas. Matplotlib is an amazing 2D and 3D graphics library for generating matematical plots.It includes: Support for LATEX formatted labels and texts …
I was reading a very interesting article on R-Bloggers, “Choosing R or Python for Data Analysis? An Infographic”. The Johns Hopkins Data Science Specialization makes a clear choice towards R. Also, this looks a good choice if you have to point jobs in this area. However, python is a generic purpose language and it is …
