You have a distance sensor HC-SR04 and a series of distance observations, assuming the target does not move you want to establish the best or most correct measure. The particular sensor used is a HC-SR04, of which an analysis of the accuracy and performances is presented here: in the analysis, as I do not have any specific …
What you learn during your lifetime will hopefully stay with you for the rest of your life. However, if you do not use the skills you have learned, they will get rusty, and if you do not sharpen them from time to time, you will find that they will be not any more readily usable …
Let’s go to the point: Finally Python has what R used to have since a looong time ago with Shiny. This is nothing less than Python Dash, a Python framework for building analytical applications (in the author’s own words). The library is based around Flask and Plotly, the installation is pretty easy and it is …
I have found out a couple of days ago that the evolution of the libraries in the Python ecosystem is FAST. It is not only fast, it is exceptionally fast. In my opinion some of these libraries are evolving together with the market and mainly for market reasons (one of these libraries is Pandas, part …
Update: The content of this article is no longer applicable for this tablet model. Termux and Jupyter Notebook still work, however Termux does no longer support (for a long time) Android 6.0 and older. The result is that crucial libraries like Matplotlib fail to install. It is still usable but only for basic tasks. …
I have already written an article about using a SQLite database from R. I was playing recently with some data, scraped from a web site to text files, that I wanted to transform into a SQLite database. I decided to do it in python, using the sqlite3 module. After a few experiments, I noticed that …
Now something different! Well, besides trying to learn as much as possible about Data Science, Machine Learning, Big Data etc, a few weeks ago I was brutally deviated to other subjects, by being asked the following question by my fourteen years old son: “Dad, can you teach me some programming”? At that point a number …
This post is a slight deviation from the usual Data Science learning path, but I think that there may be something useful also for those wanting to include a bit of interaction in their Jupyter Notebooks. I have started teaching some python to my 14 years old son (on his request), and I decided to start by …
As I have been playing with R quite a bit and I become rusty with Python, I wanted to see how good the language detection libraries in this environment are and also how they compare with R. I have made a quick search and I found out that langdetect is one derived directly from Google …
When learning about Data Science, one of the first dilemmas that come to mind is whether to start with Python or R. As a Software developer, I felt I have a natural inclination towards Python, a very elegant programming language that can also be used to do Data Science. But as I got more and …
