Recently, I finished a personal project in which I analyzed the results of the “Who is your favorite Pokemon” survey. After that, I wanted to generate a more interactive visualization in which the user could choose a specific Pokemon and see its results. After pondering different options, I decided to do so in Bokeh because of a few reasons. First of all, you can generate your visualizations using Python only. Furthermore, it is very easy to incorporate Bokeh in Jupyter notebooks, which is great to generate a first version of the prototype. Lastly, a few colleagues of mine have used it for their projects at work and have been very happy with it.
Previously, I looked into Pokémon’s popularity from all 7 generations. However, I felt the visualizations were a bit static. Furthermore, you couldn’t get details on your preferred Pokémon. Therefore, I decided to extend this project and created an interactive dashboard using Bokeh and Binder to visualize the results of the survey. It allows you to choose whatever Pokémon you want and see its preference ranking compared to all Pokémon, compared to all Pokéon of its generation, and how did people voted for it in time during the period in which the survey was open (notice how the color of that plot corresponds to the Pokémon’s dominant color)
The newest entries of the Poké main series, Pokémon Sword and Pokémon Shield will be released later this year. However, the new generation of pocket monsters came with the news that you won’t be able to complete the national Pokédex. In other words, you won’t be able to capture all the Pokémon from previous 7 generations. In a series where “Gotta catch’em all” is its catch phrase, this caused a huge backslash by some members of the community. Their main argument was that “every Pokémon is someone’s favorite”. Is this actually true?
For some strange reason, I stumbled with a paper that I had downloaded long time ago. It explains a simple algorithm for removing artifacts in ECG signal. Since I have a short time-off after the submission of my PhD thesis (yey!), I thought it would be cool to actually code the algorithm and give it a go.
Recently, I was going through my undergraduate lecture notes. I stumbled upon an exercise which I found interesting. The task consisted in implementing the algorithm proposed by Pei and Tseng, which uses vector projection to minimize the problem of transient values when applying an IIR notch filter to an ECG signal.
Recently, quite a few friends have been finishing their degrees and preparing their final theses. A very common struggle was the actual procedure of writing the thesis document. I don’t mean sitting down and writing the content (which is already quite challenging itself), but to manage big amounts of text, figures, and (specially) references efficiently. Being such a big fan of LaTeX myself, I always recommend it. However, setting up everything for the first time might not be very intuitive for everyone, since it requires a few steps. Therefore, I decided to write this small guide on how to setup LaTeX in your computer for the first time.
I just upgraded my old laptop to a new one with Windows 8.1 installed. Putting aside the small details of getting used to a new operating system (OS), I found something that was terribly annoying
Apparently, there is an awful issue with Windows 8.1 management of the wireless adapter. This translates into an unstable, limited WiFi connection. I immediately jumped into the internet, trying to find a solution. Surprisingly, this was a very common issue. Nevertheless, it took me quite a few tries to finally fix it. If you find yourself in the same situation, I recommend you to try the following options (in this order):
When working with images, selecting a specific region of an image to work with is quite common. Therefore I made a script that allows you to generate a mask with one or more regions of interest (ROIs). The shape of the ROIs can be rectangular, elliptic, (irregular) polygon, or free-hand drawn.
Recently, I was working on a paper submission. Being a huge fan of it, I used LaTeX for the manuscript preparation. The journal’s guidelines for submission indicate that LaTeX Harvard Alphabetic Style must be used together with the BibTeX style file
jphysicsB.bst. The guidelines also instruct that references must include the title of the article/book/etc. However, the
jphysicsB style does not print it (this is not an error, that is the way it is supposed to work). How to solve this?
