Norm Matloff, Prof. of Computer Science, UC Davis

Hello! This Web page is aimed at shedding some light on the perennial R-vs.-Python debates in the Data Science community. As a professional computer scientist and statistician, I hope to shed some useful light on the topic. I have potential bias — I’ve written four R-related books, and currently serve as Editor-in-Chief of the R Journal — but I hope this analysis will be considered fair and helpful.

Comparaison selon plusieurs critères. Très intéressant.

The steadily increasing importance of data science across industries has led to a rapid demand for data scientists. It’s been said that the role of data scientist is the 21st century’s sexiest job title. If you wonder why it has become such a sought after position these days, the short answer is that there has been a huge explosion in both data generated and captured by organizations and common people and data scientists are the people who derive valuable insights from that data and figure out what can be done with it.If you go through some job advertisements for data scientists, you’ll see that expertise in data science and Python are considered as two of the most crucial skills described.In this post, we’re going to discuss why these skills are considered must for data scientists.1- What (...)

There’s little argument that open source has transformed our world. As a developer, I cannot recall a single day in the last few years where I did not rely on open source software. I’m not the exception. The majority of software engineers today rely on open source daily in their professional lives.For one, open source is dominating developer infrastructure. From operating systems (Linux in the cloud) to databases (MySQL, MongoDB, Redis) to programming languages themselves (JavaScript, Python, Java, C, PHP). It’s not just developers, it’s consumers as well. From what they run on their phones (Android) to how they access the web (Chrome, Firefox).The motivation is clear. Open source is good for humanity. It is making technology more accessible and open — anyone can build anything.Open source (...)

Python is a common language that is used by both data engineers and data scientists. This is because it can automate the operational work that data engineers need to do and has the algorithms, analytics, and data visualization libraries required by data scientist.In both rolls, the need to manage, automate and analyze data is made easier by only a few lines of code. So much so that one of the books we have read and seen in many data focused practitioners libraries in the book Automate The Boring Stuff With Python.The book covers python basics and some simple automation tips.

The company has been moving aggressively into practically every technological sector imaginable — and more often than not, they end up revolutionizing the sector they’re looking to develop. It’s now been over a decade since Go entered production, and while it might not have the install base of languages like Python and JavaScript yet, Google’s proprietary language has a lot to offer. Here’s everything you need to consider before you decide to pick up this language.Pro: ease of useWhile Go might not be as popular as JavaScript or Python, it does have one important thing in common with them: it’s eminently easy to understand.

R and Python have become the two most popular and favourite languages for the data scientists and data analysts. Both of these are similar, yet, different in their ways which makes it difficult for the developers to pick one out of the two.R is considered to be the best #programming language for any statistician as it possesses an extensive catalogue of statistical and graphical methods. On the other hand, Python does pretty much the same work as R, but data scientists or data analysts prefer it because of its simplicity and high (...)

This model was developed with Keras library (TensorFlow backend) and now is available for Python 2.7 and 3.0+.IntroductionCreating and using word embeddings is the mainstream approach for handling most of the #nlp tasks. Each word is matched with a numeric vector which is then used in some way if the word appears in text. Some simple models use one-hot word embeddings or initialise words with random vectors or with integer numbers. The drawback of such models is obvious – such word vectorisation methods do not represent any semantic connections between words.There are other language models, called (...)

From the article:

C++ has two standardized ways of printing formatted text out already: printf-family functions inherited from C and I/O streams abstraction built on operator<<. Streams are considered more modern, providing type-safety and extensibility functionalities. However, printf have some notable advantages, too — at the cost of lost type-safety, user can use an interface that looks familiar to almost all developers, allowing for some ways of localization and more readable syntax. And then, there is fmt — yet another text formatting library, inspired by design already available in languages like Python and (...)
