I was invited to join the Coursera Data Science community a few weeks ago. I did, and this is a very interesting meeting point where people with any degrees of Data Science experience and skills meet and discuss several related topic. As I feel I am still not mature as a Data Scientist, I followed …
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 …
Well well. These days the terms “Machine Learning” and “Deep Learning” seem really to be all over the places. But what is all this hype. about 25 years ago, for my university thesis at Pisa University, I and my team mate have implemented a Functional programming language based on structures called “Hypergraphs” that specialized in …
Hans Rosling is one of the reasons why this blog exists. He defined himself as a “edutainer” and his way of explaining statistics to the public was simply mind blowing. I have been directed to the web site of his foundation, gapminder.org, by one of the courses I was following, I think it was “Analytic …
I just went through the experience of completing the Johns Hopkins University Data Science Specialization on Coursera. The last course of this specialization was the Capstone project, which consists basically in learning about a new subject, Natural Language Processing (or NLP in short) and producing a Shiny application hosted on Shinyapps.io that predicts the next word a …
This JH Data Science capstone project is transforming into a nightmare, especially because of R and tm, which do not do what they are supposed to do. True I have changed architecture and PC in the middle, but this is not the problem. R and R packages like tm evolve fast and sometimes too fast …
I am now aiming at the Capstone project in the Coursera’s Data Science Specialization from Johns Hopkins, to finish the Specialization. The project is focused on predicting the next word that somebody is going to type, based on several databases to be used to build up the prediction algorithm. There is a lot of previous …
Here it comes, summertime. Last year I was particularly active with this Blog and my quest to learn as much as possible about Data Science, Python, R etc. Many MOOCs and books later, and with only the Capstone project that separates me from achieving the Data Science Specialization, I have the need to slow down …
I almost did not notice, but last 15th May was my site’s become one year old! Wow! In one year, this is the basic traffic data: Number of visitors as of now : 3730 Number of visits: 26085 My free hosting profile does not allow me to know from where you visit, I choose to …
One thing about learning is that the more you learn the more you feel ignorant about the subject you are trying to learn about. Sometimes you would like to see a particular aspect treated or explained in a different way. Some other times you would like to have an example. The net gives a big …
