I have written a handful of articles on Medium: my goal is to share them with as many readers as possible.
Having goals and expectations is essential to foster motivation. Exceeding expectations is a powerful source of motivation, but not meeting them can put the whole project in danger.
Based on a scientific approach, I wanted to set reasonable expectations so that I maximise my chances to exceed them, and benefit from this motivation boost to move faster towards my goal.
Before diving into technical details, have you heard about Make Your Brain Work by Amy Brann? …
Release data science work through online applications creates tangible value for your customers. In this article, I provide a step by step tutorial to deploy a Shiny application using shinyapps.io, a cloud service developed by RStudio which offers a free pricing option.
The 3 most common cloud services used by data science teams are Amazon Web Services (AWS), Google Cloud Platform (GCP) and Microsoft Azure (Azure).
Leveraging Docker container technology, these platforms may provide entry points to machine learning models or analytics web applications. These tools are then accessible online.
Amazon, Google and Microsoft offer free trials, which simply put, consist in a given amount of money to test the platform for a period of 1 to 12 months. In the end of the trial, you will have to upgrade to a paid account to keep using the service. …
Web applications have become very popular in the data industry to give access to self-service analytics tools. In a nutshell, these applications enable users to run data processing scripts without any technical knowledge.
Extremely flexible, these standalone tools may contain basic features (e.g. data visualization) as well as advanced functionalities (e.g. label training data for machine learning).
Having a background in web development is not required for data experts. High-level libraries were developed for the most commonly used programming languages in the industry: Shiny (R) and Bokeh (Python).
Below in this article, you will find a total of 24 explained lines of code to build a Shiny application from scratch: it can be used as a starting point for your projects. …
There are more than 16 000 packages on the Comprehensive R Archive Network (CRAN) that gather a lot of commonly used methods in data science projects. Time runs fast, and it may takes days to code functionalities for sometimes basic tasks… Fortunately, we can leverage many packages to focus on what is essential for projects to be successful!
The most common way is to install a package directly from CRAN using the following R command:
# this command installs tidyr package from CRAN
Once the package is installed on your local machine, you don’t need to run this command again, unless you want to update the package with its latest version! …
