Portuguese explorer wins award for artificial intelligence tool for exoplanet exploration - society

The creation of an artificial intelligence tool that allows highly accurate data collection on exoplanets, which contributed to the implementation of the mission of the European Space Agency, won the researcher Louis Simoins in the Ariel Machine Learning Data Challenge.

The award was presented after Louis Simoins improved his ability to detect exoplanets by capturing the light emitted from a star using a highly accurate algorithm.

The task was launched by the European Space Agency (ESA) to provide the necessary conditions for the study of exoplanets (planets that orbit a star but do not belong to the solar system) in the Ariel mission, which will be launched in 2029. …

For the Portuguese researcher who “occasionally competes in machine learning for space,” the competition had the advantage of developing his “ability to solve problems and apply different algorithms” and keep abreast of developments in artificial intelligence. “.

To a problem that he considered “excellent because of its relevance and complexity,” he answered by creating a solution with an average error of 0.00007.

“The specific task – the detection of exoplanets – is solved by different approaches, but the one that turned out to be more successful is associated with the study of light curves, therefore, the light that comes to us from the star, and when the planet passes forward in its orbit, the shape that takes this curve tells us a lot about the planet, ”explained Luis Simoes to Luce.

He admits that this method has already been used to “identify thousands of exoplanets,” “but this mission has a very ambitious goal,” which includes “understanding the chemical composition of the atmospheres of these planets.”

“It will only be possible with tools that are not there today, hence the interest, 10 years ago, to start learning and challenge the community,” added Luis Simoins.

The solution he came up with does not provide any new data, but Luis Simoins created “a model, almost error-free (…) high-precision model.”

This accuracy matters, because “the question of the chemical composition of the atmosphere is the subsequent processing of the data that the algorithm will give.”

“There he already enters into other areas of astrophysics, but the fact is that if an incorrect interpretation is made at this stage of the data interpretation chain, then the next steps will be misled as to what the real characteristics of the planet will be.”, Materialized.

For this, the algorithm is programmed “automatically based on the training data”.

To this end, the team leading the ESA mission “has created synthetic data using simulators that recreate with maximum accuracy at the moment what data the mission will collect in the future.”

This data was distorted “due to data distortions that may arise during the mission – due to thermal fluctuations, due to the whole problem of measuring hundreds of light years, how many photons are coming from different sources”, but knowing what the original data was , it was possible to assess the degree of accuracy of the presented solutions.

“We are several years away, this is not the final model, but it is already a significant step towards achieving the levels of accuracy that the mission wants to have,” the researcher said.

Luis Simoins began working on the use of artificial intelligence for solving space problems, creating “systems for Airbus and ESA to control the landing of ships on other planets.”

In 2008, due to the crisis, he moved to the Netherlands, where he began to cooperate with the ESA.

He returned to Portugal in 2018, where he founded ML Analytics with his wife.

Portuguese historical films will premiere on 29 December.



Portuguese historical films will premiere on 29 December.

Method Media Bermuda will present the documentary FABRIC: Portuguese History in Bermuda on Thursday, December 29 at the Underwater Research Institute of Bermuda.

A spokesperson said: “Method Media is proud to bring Bermuda Fabric: Portugal History to Bermuda for its 5th and 6th showing at the Bermuda Underwater Observatory. In November and December 2019, Cloth: A Portuguese Story in Bermuda had four sold-out screenings. Now that Bermuda has reopened after the pandemic, it’s time to bring the film back for at least two screenings.

“There are tickets For $ 20 – sessions at 15:30 and 18:00. Both screenings will be followed by a short Q&A session.

Director and producer Milton Raboso says, “FABRIC is a definitive account of the Portuguese community in Bermuda and its 151 years of history, but it also places Bermuda, Acors and Portugal in the world history and the events that have fueled those 151 years.

“It took more than 10 years to implement FABRIC. The film was supported by the Minister of Culture, the Government of the Azores and private donors.

Bermuda Media Method [MMB] Created in 2011 by producer Milton Raposo. MMB has created content for a wide range of clients: Bermuda’s new hospital renovation, reinsurance, travel campaigns, international sports and more. MMB pays special attention to artistic, cultural and historical content.

Maestro de Braga is the first Portuguese in the National Symphony Orchestra of Cuba.



Maestro de Braga is the first Portuguese in the National Symphony Orchestra of Cuba.

Maestro Filipe Cunha, Artistic Director of the Philharmonic Orchestra of Braga, has been invited to conduct the Cuban National Symphony Orchestra, as announced today.

According to a statement sent by O MINHO, “he will be the first Portuguese conductor to conduct this orchestra in its entire history.”

In addition to this orchestra, the maestro will also work with the Lyceo Mozarteum de la Habana Symphony Orchestra.

The concerts will take place on 4 and 12 March 2023 at the National Theater of Cuba in Havana.

In the words of the maestro, quoted in the statement, “these will be very beautiful concerts with difficult but very complex pieces” and therefore he feels “very motivated”.

From the very beginning, Rachmaninoff’s Piano Concerto No. 2 will be performed by an Italian pianist (Luigi Borzillo), whom the maestro wants to bring to Portugal later this year. In the same concert, Mendelshon’s First Symphony will be performed.

Then, at the second concert, in the company of the Mexican clarinetist Angel Zedillo, he will perform the Louis Sfora Concerto No. 2. In this concert, the maestro also conducts Tchaikovsky’s Fifth Symphony.

“This is an international recognition of my work. An invitation that I accept with humility and great responsibility. I was surprised to learn that I would be the first Portuguese member of the Cuban National Symphony Orchestra. This is a very great honor,” the maestro said in a statement.

“I take with me the name of the city of Braga and Portugal with all the responsibility that goes with it, and I hope to do a good job there, leaving a good image and putting on great concerts. These will be very special concerts because, in addition to performing pieces that I love, especially Rachmaninov and Tchaikovsky, I will be directing two wonderful soloists who are also my friends. It will be very beautiful,” concludes Filipe Cunha.
