Data and Climate Modelling: video and highlights

On April 17th, we hosted the 2nd episode on our “Data and Sustainability” series. The topic of the session was: “Data and Climate Modelling”. We had a full room ready to carefully listen to all our speakers.

We started the evening with Francisco Javier Doblas-Reyes (Barcelona Supercomputing Center) talking about digital twins on climate; followed by Rachel Lowe (BSC), who provided a great overview on the relationship between climate challenges and health issues across the globe!

Following Rachel’s talk, we had Ignacio Villanueva (RAVENWITS) on stage to highlight the main applications of machine learning on meteorology!

We closed the night with our remote speaker Ferran Alet Puig (Google DeepMind) who gave an extensive talk on their research and on the climate models they have been developing during the last years!

We ended the evening with some pizza and drinks to follow up on questions and very interesting discussions!

Thanks everyone for coming, especially to the speakers for accepting our invitation! Also thanks to Adevinta Spain for hosting us!

P.:D Stay tuned to know about the upcoming events!

New event: Data and Climate Modelling

Following the remarkable success of our inaugural event in the “Data and Sustainability” series, BCN Analytics is thrilled to present the topic of our next session: “Data and Climate Modelling”.

The goal of this series of events is to encourage prestigious researchers and industry leaders to inspire our community’s passion for forging a sustainable future. Through talks and discussions, they will explore the transformative potential of data-driven solutions for a more sustainable world, spanning topics such as decarbonization, predictive climate modelling, the blue economy, and beyond.

The first talk of the afternoon will be given by Francisco Doblas-Reyes and Rachel Lowe, from the Barcelona Supercomputing Center. They will cover how the BSC is using data and computation to make climate projections based on different emission scenarios.

In the second talk, Ignacio Villanueva from RavenWits will explain how Deep Learning’s expansion into weather prediction will not only popularize and enhance the forecasting of weather-related variables but also extend to improving predictions for renewable energy production.

Finally Ferran Alet, Research Scientist at Google DeepMind, will show that GNNs trained on large-scale dataset can predict global weather forecasting at a state-of-the-art level, improving on physics-based models that have been developed for decades. Predictions translate to real world impact like better extreme temperature predictions as well as better.

Event will be on April 17th at Adevinta offices (Barcelona) and will start at 18:30h.

After the talks, food and drinks will be provided so we all have time for some networking and follow-up discussions.

New events – Data & Sustainability. Episode 1: The role of Data in the Decarbonization and Energy Transition

How data is being harnessed to tackle some of the biggest challenges our planet is facing? At BcnAnalytics we are organizing an informative meet-up series exploring the vital role of data in the sustainability movement.

In our events we will feature thought leaders and industry experts who are leveraging data to create a more sustainable future. They will share their experiences and inspire us in the path towards Data-Driven Solutions for a More Sustainable World. We will cover a broad variety of topics such as decarbonization, predictive modeling for climate risk, blue economy and many others.

Our first event will be about the role data in the Decarbonization. Where are we now? How does the future look like? What is the role of Agriculture? Can Data help to accelerate Decarbonization? According to International Energy Agency (IEA), global energy-related CO2 emissions grew in 2022 by 0.9%, or 321 million tonnes, reaching a new high of more than 36.8 billion tonnes. Emissions still remain on an unsustainable growth trajectory, and experts are calling for stronger actions to accelerate the clean energy transition to meet energy and climate goals.

In this first event we will have Anne-Lise Laurain (Incubatenergy Europe) and Pablo Rosado (Our World in Data) as speakers.

Event will be on June 19th at Adevinta offices (Barcelona) and will start at 19h. We will open doors at 18:30. Do not be late!

After the talks, food and drinks will be provided so we all have time for some networking and follow-up discussions.

New event: Gender Gap in Data and AI

While women account for roughly 55% of university graduates their presence in STEM-related sectors like software development, engineering or analytics is significantly lower. According to various surveys from WEF, Global Gender Gap Report and BCG, women make up only between 15% to 22% of all data science professionals.

In BcnAnalytics we want to reflect on the gender gap in the field of Data Analytics and Data Science. Why is this happening? What can we do about it? So we are organizing an event that will focus on Gender Gap.

When: November 22nd, from 19h to 21h.

Where: Adevinta offices at Barcelona

As speakers, we will have Elisenda Bou-Balust (co-founder and CTO at Vilynx, now Head of Apple Media Knowledge) and Marta Cardona (Data Lead at Holaluz).

After the talks food and drinks will be provided so we all have time for some networking and follow-up discussions.

New event: Results from Datathon Against Racism

From March 25th to April 1st, we organized a Datathon Against Racism. Several teams had to build a model to classify text messages as racist or as not racist. We had great learnings and tons of fun.

Now we want to share some of the great work done during the Datathon and we have asked three of the teams to share the technical approach they took to build their NLP models and also the insights they were able to generate.

We will also explain how we prepared the Datathon with more emphasis on how built the dataset (which we will make publicly available).

When: June 28th, from 18h to 20:30

Where: Adevinta offices in Barcelona (Carrer de la Ciutat de Granada, 150).

If you want to attend in persona, please register here. You will also be able to join online (we will provide the link in the coming days)

Datathon: the kick-off

Last Friday, March 25th, we had the inauguration event of our Datathon against racism. We had a full-house, with members of the 10 teams which will be competing, representatives of all sponsors and also members of several organizations fighting against racism.

After a short introduction we got two great speeches by Ténzul Zamora (founder and director of The Crownz Project, vice president of SIETAR España and GdT Antiracism of PSC) and Adam Majó, (Director General per a la promoció i defensa dels Drets Humans at Generalitat de Catalunya). Then our sponsors (Adevinta, Colt Technology Services, Digital Future Society and Holaluz) had the chance to share a few messages. After that we explained the Data Challenge to all participants. And finally time for beers and pizza!

Datathon against racism: Details

We are almost ready for our Datathon about racism.

10 teams will be competing to build a build a model that can automatically classify text messages as Racist or not Racist. We will be offering two prizes each of them of 1.500€ . The kick-off will take place on March 25th at Adevinta offices. You can get more details in this page.

This Datathon is possible thanks to the support of our SPONSORS:


Colt Technology Services

A new datathon is coming

As you know we had to cancel our meetups due to Covid-19. Hopefully we will be able to have them back very soon.

In the meantime we have been quietly working to prepare a new Datathon.

As a topic we have decided to focus on Hate Speech, a critical issue.We are really excited about this Datathon and we plan to celebrate it between March 25th and April 1st with the support of Adevinta, Holaluz and CNAAE (Comunidad Negra Africana y Afrodescendiente en España).
