Este es un artículo donde explico la metodología que utilicé para realizar un análisis de datos de redes sociales para las elecciones de Guatemala.

El reto de este análisis consistió en reducir el impacto de los sesgos de representatividad en las encuestas y los sesgos maliciosos en redes sociales.

Las elecciones a pesar del netcenter y las fake news

Como es costumbre, desde hace ya dos elecciones atrás  1,2 , he estado analizando datos sobre la intención de voto en las próximas las elecc...

Usually we focus on measuring -and hence valuing- outcomes rather than processes. The push for productivity in a fast paced world makes us to focus on the "what" while paying little attention to the "how." In some sense, this approach treats systems as black boxes where the most valuable aspect is the product itself.

#PMA_Value

The idea of value is ubiquitous in our modern world. Particularly, how we assign and measure value determines most of our actions, from an individual to a systematic level. It is well known that systems tend to optimize to what is measured. Measurements become a tacit goal for most of our modern systems, higher education being one of them. Two important questions arise: what we measure and how we measure it. Implicitly, the answer of these two questions reflect what we value.

I will be taking on at least one new PhD student in automatic theorem proving in October 2023. If you might be interested in applying, it is bureaucratically easier if you do so before January 6th, though not completely essential. For more details about the project, have a look at our website, which is still under development but which contains quite a lot of material. 1/

#PMA_TheGame

The Game here for me is more of a micro-blogging site. That is, less suitable for live commenting. Since the character limit is longer, the information load is higher, which would make the flow of this to be slower.

My Game here would be to create blog-like entries by topics using hashtags for their titles.

On the arXiv today, a 7 page proof of the 4 colour theorem! It uses generating functions. https://arxiv.org/abs/2212.09835 #graphtheory #arxiv
A non-constructive proof of the Four Colour Theorem

The approach is through a singularity analysis of generating functions for 3- and 4-connected triangulations, asymptotic analysis, properties of the ${{}_3F_2}$ hypergeometric series, and Tutte's enumerative work on planar maps and chromatic polynomials.
