Available at https://github.com/opsabarsec/editGoogleSheets A common request that you may get from colleagues not used to programming “could you please pass me these results saved to Excel format?”. Or “we write data every day into this spreadsheet, we would like to automate an analysis every x days”. Having to download, save…

The code discussed in this post is available at: https://github.com/opsabarsec/titanic_on_databricks Small note beforehand, for Data Science newbies or simply for people who think Deep Learning = Magic. Better data, smarter features engineering will beat better algorithm 9–0. Data Science is studying data, not models. But having said it, experimenting several…

The code discussed in this post is available at: https://github.com/opsabarsec/titanic_on_databricks Data Science is getting more and more automated. Tuning coefficients? Adding layers to your neural network, etc. are tasks that soon will be regarded as the work of artisans who manually bind books. Extract, Transform, Load (ETL) and sometimes simple…

Knowing where the virus is spreading faster, identifying clusters etc. are extremely important information to tackle pandemic. But such information is not so straightforward to obtain. There are a few challenges : - data…

Code available at: https://github.com/opsabarsec/NLP--film-genres-from-synopsis Extracting keywords from a text is one of the widest application of natural language processing (NLP). Depending on a specific problem, approaches can be various. Unsupervised learning can be used to identify, for example, a spam message when few special keywords are obtained. When it comes…

Text extraction from an image is becoming one of the most common application of artificial intelligence. It is something you approach since the beginning of your deep learning coding career when you confront the MNIST dataset and read about convolutional neural networks (CNNs). As you advance, you will need to…

Chemometrics: the democratization The late 90’s in Italy, Turin, faculty of Chemistry. Smartphones were not even conceivable, few geeks had already heard of things like “ Netscape navigator running on Palm Pilot”. Undergraduate students were thought to program in Fortran running on Win95 and crashing on Win98. Few could use Matlab installed in…

The question I keep getting every time I tell someone about my academic background: “ Why did you completely change career from working in a lab as Chemist to working on a PC as Data Scientist?”. The complete answer would require even more than a blog post. I try to…
