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.

Portugal international Bruno Fernandez rose to prominence during the World Cup in Qatar. The star, who also plays for England’s Manchester United, scored one more goal than Cristiano Ronaldo and played a crucial role in securing Portugal a place in the round of 16.

At the age of 28, the Portuguese has a very quiet personal life and is the father of two children. The star married in 2015, when he was 21, the first and only girl in his life, the Portuguese Ana Piño.

Bruno and Ana’s love story began in Porto, Portugal. They met at the school where they studied together, started dating and since then have not parted.

At the beginning of the relationship, Bruno played for the Portuguese club Boavista, so he easily managed to be with Ana and train.

When the player needed to move to Italy to improve his career, Ana supported the star and two years later she was asked to marry him.

They married at the end of 2015, and in 2017 they had Matilda Fernandez, the couple’s first daughter. Three years later, in 2020, Goncalo Fernandes was born, who completed the team of football fans played by Bruno.

Ana, Mathilde and Gonzalo are always present in the Portuguese games, which is very important in raising children.

"Now you die, I'll burn everything."  Portuguese man arrested in Spain suspected of setting wife on fire - Observer

Catalan justice has ordered the preventive detention of a man of Portuguese nationality for allegedly burning a 48-year-old woman alive. The suspect doused his companion with alcohol with rosemary and acetone, set fire to the house in which he lived in Lleida, while telling her: “Now you will die, I will burn everything.”

According to El Periodico, the 39-year-old man was detained on Monday, while a companion was rushed to the burn unit of the Hospital de la Vall d’Hebron, where she still has burns over 18% of her body.

or country Details that, in addition to trying to burn her, the man tried to strangle her. According to the indictment seen by the same newspaper, the victim went to bed around 11:00 pm, and the partner was still at home. Shortly after that, he left, and when he returned, he began to poke something in the woman’s face. “I will kill you,” I told him.

Companion managed to get out of bed, but the alleged intruder splashed acetone in his face. It was there that the man allegedly set fire to the house and tried to strangle her. The woman ran away, but she was pulled when she went down the stairs: “Let’s go, I’m on fire too.”

The building where the couple lived was destroyed by fire. However, the man denies this version, arguing that there was a quarrel, but that when he came home, there was already a fire. However, the judge who heard him considered that the explanations were “inaccurate” and there were “contradictions”.

When asked why the woman came up with this story, the Portuguese man limited himself to the fact that “when she is annoyed”, her partner “does not know what he is saying”: “When he gets angry, he tries to hurt everyone.”

In turn, one of the witnesses – a neighbor of the couple – told the authorities that the couple quarreled, despite the fact that they had never witnessed a single episode of physical violence. On Monday, a neighbor overheard their quarrel and went out on the balcony at dawn and heard the cry of a 48-year-old woman: “Don’t kill me, don’t kill me, don’t kill me.”
