Good morning.
President Trump heads to the border to argue for a wall, young South Koreans try to climb out of mountains of debt and A. I. holds promise for healthcare. Here’s the latest:
President Trump is headed to the border city of El Paso — a Democratic stronghold in Texas — to again argue for his wall. In his State of the Union address last week, he claimed a wall in El Paso lowered crime rates there.
Not far from Mr. Trump’s rally, Beto O’Rourke, a former Democratic congressman from the city and a potential presidential candidate, will hold a major counterrally. He has pointed out that El Paso boasted one of the lowest crime rates in the country before any kind of barrier was built there.
On the ground: Ahead of the events, people cross the political spectrum in El Paso had a message for Mr. Trump: Don’t speak for us.
Looking ahead: The dueling events come as congressional efforts to reach a deal over border security faltered, bringing the government perilously close to yet another partial shutdown on Friday.
Related: California is expected to become the second state to withdraw hundreds of its National Guard troops from the southern border, a sharp rebuke to the president’s claims that migrants present a national security risk.
In a new study, researchers from universities in the U. S. and China built a highly accurate system that could automatically diagnose common childhood conditions — from influenza to meningitis — after analyzing the patient’s symptoms, medical records, lab results and other clinical data.
Details: The system used a neural network, a breed of artificial intelligence, to digest the electronic health records from more than 1.3 million patient visits at a pediatric hospital in China. In some of the cases, the system’s analysis rivaled the performance of experienced physicians.
Why it matters: Able to recognize patterns in data that humans could never identify on their own, the system suggests that A. I. could assist doctors in diagnosing complex conditions, potentially transforming the health care industry and reducing the chances of incorrect diagnoses.
Caution: Even experts have difficulty understanding why neural networks make particular decisions, so extensive testing is needed to make sure that they are reliable.
Prosecutors dropped an extradition case against a soccer player from Bahrain, Hakeem al-Araibi, who said he would be tortured if he were returned. He is expected to head to Australia soon, where he has refugee status.
