An AI could detect first signs of dementia | Digital Trends Spanish

A group of scientists from the University of Cambridge they have created an artificial intelligence system that could diagnose cases of dementia through a simple scanner cerebral. The system is currently in the testing phase and, if effective, could become an important tool in the treatment of patients. The latter because, according to scientists, early detection of future diseases would allow treatments to start before the first symptoms appear, which in turn would delay the effects of diseases and even prevent further damage. Shutterstock.There is even talk of the possibility that the effects of dementia, with the right treatment and at the right time, never manifest themselves during a person's life. Currently, diagnoses of some type of dementia require several scanners and analysis ...

Twitter algorithm prefers young, fair-skinned faces | Digital Trends Spanish

Twitter reported the results of a contest to find the bias in its algorithm that it uses to crop images. The results demonstrated what the users themselves warned a few months ago: that the algorithm used by the platform favors the faces of light-skinned and young people. The contest was launched by Twitter as a way to improve its controversial image cropping algorithm, which was disabled in March after it was found to favor some faces over others. In the instance, he encouraged users and hackers to help discover the potential damages that could be generated. According to the company, the winners provided a "novel perspective to address the problem of unintentional damage" and the avenues of exploitation that could exist in the algorithm. One of the contest winners showed that the algor...

Algorithm identifies effective drugs against COVID-19 | Digital Trends Spanish

The battle against COVID-19 is taking place on several fronts. On the one hand, research work with vaccines does not rest; on the other, dozens of existing drugs that could be effective against the coronavirus are being analyzed. According to a study published in Science Advances, researchers from the University of Cambridge They have used an artificial intelligence system to study the proteins of COVID-19 and thus identify if there are ways to mitigate the effects of the disease through the use of drugs that have been developed for other purposes. In total, "thousands of proteins are involved in the infection," the study authors explain. "Some participate more actively, while others appear as a consequence of contagion." PixabayIn total, the researchers concluded that there are abou...

An algorithm helps Amazon fire its delivery people | Digital Trends Spanish

A report published by Bloomberg again accounts for the poor working conditions in which Amazon workers have to work, especially those who are part of its Flex delivery program. To ensure deliveries are always on time, the company uses millions of outsourced drivers for its delivery program started in 2015. Amazon Flex is a platform that allows people to use their own vehicles to carry packages and other purchases that consumers make. According to the article, workers who work at Amazon Flex are constantly under performance review. Their ratings are awarded through an algorithm that monitors them frequently. However, the note also says that delivery men can be fired for no apparent reason. One worker said that her grade in the program dropped after she was forced to stop due to a punct...

A Google error turned an engineer into a murderer | Digital Trends Spanish

This is the type of email that no one would want to read. Hristo Georgiev was checking his inbox when he found an email where a former co-worker gave him a strange warning. According to the message, when you googled his name, Hristo's image was linked to a Wikipedia article about a dangerous serial killer. The problem is that Georgiev shares his name with a Bulgarian rapist and serial killer, popularly known as The Sadist, who killed five people between 1974 and 1980. Now, it is enough to enter the article to realize that Hristo and the murderer are different people, but even so this engineer warns about the “darker implications” that this error could have. The problem appears to have been caused by Google's Knowledge Graph algorithm, which mistakenly matched Georgiev's photo with the ...

MIT demystifies the relationship between Basque and Iberian languages ​​| Digital Trends Spanish

A system that allows a dead language to be deciphered automatically, without the need for advanced knowledge of its relationship with other languages, has been developed by scientists from the Massachusetts Institute of Technology (MIT). The development of researchers at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) is also capable of determining whether there are relationships between languages. In fact, it allowed corroborating studies that suggest that the Iberian language is not as closely related to Basque, as was originally believed. The team's goal is that, with a few thousand words, the system will be able to decipher the lost languages ​​that have hampered the work of linguists for decades. How does it work MIT / SRK Branavan The platform is suppo...

Algorithm is unmasking misogynists on Twitter | Digital Trends Spanish

The violence unleashed and the verbal disqualifications on Twitter have made the social network take a series of measures to clean up the interactions of its users, but efforts have not been so great to avoid, for example, machismo. To fix that problem, researchers at the University of Queensland in Australia created an algorithm that is capable of detecting misogynistic attitudes. The team developed the tool based on Artificial Intelligence and an in-depth study of more than 1 million tweets extracted. They then refined the dataset by searching the posts for three abusive keywords: whore, whore, and rape. They then categorized the remaining 5,000 messages as misogynistic or not, based on context and intent. These tagged tweets were then sent to a machine learning clas...

Playstation will detect users by movement | Digital Trends Spanish

Just a few months after the PS5 is released, Sony is already working on some innovations that it wants to launch in the future. A patent application that revealed Arstechnica, talks about a new authentication method. This system would be based on the movement of users through the command control of the console, and thus avoid passwords and fingerprints. “To log into their account, a user often has to enter a password, which can be seen by other users. Additionally, once a user has entered their password, a situation arises where the user remains logged into their account unless the user subsequently performs a logout operation, which may result in another user [sic] potentially gain access to the user's profile, ”the patent begins. That's why Sony wants to implement ...

English students are discriminated by algorithm | Digital Trends Spanish

The coronavirus and the inability for a good part of the year to be able to attend schools, has made a very controversial decision in the United Kingdom that has the educational community in trouble. It turns out that the exam takes place every year A-Levels, known as the final high school tests, however, due to the contingency of the pandemic, in 2020 the government decided that an algorithm would place the grades. The main problem with the algorithm is that, in addition to the notes posted by the teachers, it took into account the history of the educational center and the geographic location where it is located, as well as its socioeconomic conditions. This triggered that at least 300,000 students saw their real grades drop by 40%, losing access to universities. This ...
