Do not miss our next event: Data & Ethics

In BcnAnalytics we are really passionate about Data. At the same time, we also have some concerns about ethical aspects of a data-driven world. So, we are pleased to announce our next event will focus on “Data and Ethics”.

Event will be on April 11th 19h at MWC, and as usual doors will open at 18:45.

We will have two great speakers in our panel: Carlos Castillo (Distinguished Research Professor at Universitat Pompeu Fabra) and Gemma Galdon (Founder at Eticas Research & Consulting and Researcher at Universitat de Barcelona). Both will share their views on ethical aspects when using data and building algorithms. They will raise concerns around bias, discrimination and opacity in a data-driven world and how this might negatively affect certain people on their lifes.

As usual, after the talks we will have time for networking and free cold beers.

If you want to attend, you can register here

This event could not be possible without the collaboration of Mobile World Centre.




THE BCN AIR QUALITY DATATHON CHRONICLES

On Sunday January 21st, at about 14:00, the winners of the BCN Air Quality Datathon were announced by the jury. This scene concluded an intense weekend in which 12 teams formed by data scientists with all kinds of backgrounds and coming from different countries worked hard to achieve a clear goal: use data to improve the air quality predictions that the Barcelona Supercomputer Center (BSC) performs with the CALIOPE system.

It all began on Saturday 20th at 9:00, when the first participants arrived and collected the wonderful green t-shirt with the motto “Keep modelling and mind the air quality”. Then, after the kind words of our host Vicenç Villatoro (the director of CCCB), Janet Sanz Deputy (mayor for Ecology, Urbanism and Mobility #Barcelona), and people from the companies that made the event possible (the sponsors Gauss&Neumann, Social Point and Holaluz), the datathon was presented and the challenge made public to the participants.

Given the concentration of NO2 observed hourly in 7 measurement stations, and hourly predictions of the concentration of NO2 performed every day with the CALIOPE system, the challenge was to find the model that best predicted the probability for a set of days in 2015 to exceed a threshold concentration of 100 µg/m3 at least in 1 hour of the day.

After that, the teams had about 24 hours to design and implement their models and submit their predictions. At that moment, the strategies of the different teams started to emerge. Some discussed how to build the model before implementing it, while others started coding straight away to make the most with the available time. While experienced teams used a rigorous methodology to work in parallel at a fast pace, some newbies struggled to find a way to combine different languages or pass data from one computer to another. All of this in an environment of concentration but also of relaxation.

After a night in which some participants (and some organizers) did not sleep much, the predictions were finally submitted on Sunday morning. It was the turn for the teams to describe their work in 4-minute presentations in front of a jury formed by Carlos Pérez García-Pando, Kim Serradell and Maria Teresa Pay from BSC, Marc Torrent from the Big Data Center of Excellence, Salvador Lladó from Leitat, and Manuel Bruscas and Didac Fortuny from BcnAnalytics.

Two awards were given: The accuracy award, which was given to the team with more precise predictions, consisted on 2000 € and a pass for the Mobile World Congress 2018 for each member of the team. The winning team was “Worthless Without Coffee”, who performed a time series prediction using concentration values of the previous days, predictions of the CALIOPE system, concentration increases, some calendar variables and the characteristics of the measurement stations. They have kindly agreed to share their code, which can be found following this link.

The creativity award took into account the originality in facing the challenge and the insights found within the data. The winners of this award were the team “Dreamers”, who proposed some appealing policies to improve the air quality, and the team “Alpha”, who made useful suggestions to the members of the BSC to improve their predictions based on what they observed within the data. Each team won 600€ and passes for the 4 Years From Now 2018 event.

The datathon is over but there is still room to improve air quality predictions. For this reason, the data set will be kept public and any restless data scientist will be able to access it and keep working on the problem. Following this link anyone can download the data and the documentation given in the datathon. So, data scientists, keep modelling and mind the air quality!




Datathon about pollution in Barcelona

 

A few years ago, when we created Bcn Analytics our vision was Barcelona can become a European analytics hub. Our ambition was to foster that different members of community (business, academia, data professionals) could meet and share experiences and knowledge. Now, 3 years after, we feel proud of we accomplished. We have organised 10 meet-ups where fantastic speakers from great organisations have shared their expertise: we had guests from Google, New York University, King.com, La Caixa, Telefonica, Schibsted, Social Point, BBVA, IPSOS or Vistaprint, among others. We also had the chance to organise two Datathons with Social Point so data scientists could compete to win some prizes while having fun with data.

But when we created BcnAnalytics we also wanted to contribute to make Barcelona a better city. We truly believe data can also be for good. So, we are proud to announce we are co-organising the first “Barcelona Pollution Datathon”. What is the Datathon about? First let me share some data points. According to this article 95% of people in Barcelona are breathing more particle pollution than is recommended by World Health Organisation. If you think about, this is scary. In fact air pollution in Barcelona rises by 48% on public transport strike days, study reveals. We thought we could do something to raise awareness on pollution levels and also get data scientists involved. And we decided to co-organise an event with CCCB, BSC, Leitat and Eurecat. That was the spurn of this first “Barcelona Pollution Datathon”.

The Datathon is going to be part of the exhibition “After the End of the World” which is being organised by CCCBB. Participants of the datathon will have to build a prediction model on Barcelona pollution levels. We have more than 3.000€ in prizes thanks to our sponsors Social Point, Holaluz and Gauss & Neumann. We also have the support of Mobile World Congress.

Datathon will be on January 20th and 21st and registration is now open through this link https://docs.google.com/forms/d/e/1FAIpQLSf6cMswcosinjbC6-VS13Ih4fIYUPaC3LYV5VcOGxLIiK8-IQ/viewform .

Do not miss it and let people know they can make a difference and also have access to great prizes.
