A Machine Learning Pipeline to Examine Political Bias with Congressional Speeches


Machine learning, with advancements in natural language processing and deep learning, has been actively used in studying political bias on social media. But the key challenge to model political bias is the requirement of human effort to label the seed social media posts to train machine learning models. Although very effective, this approach has disadvantages in the time-consuming data labeling process and the cost to label significant data for machine learning models is significantly higher. The web offers invaluable data on political bias starting from biased news media outlets publishing articles on socio-political issues to biased user discussions about several topics in multiple social forums. In this work, we introduce a novel approach to label political bias for social media posts directly from US congressional speeches without any human intervention for downstream machine learning models.

Federal agencies buying up Chinese drones previously deemed a national security threat: report

FOX News

Fox News correspondent Peter Doocy has the latest on the president's speech at the U.S. on'Special Report' Federal law enforcement agencies in the Biden administration are reportedly purchasing surveillance drones from China that have previously been labeled a potential national security threat by the Pentagon. The U.S. Secret Service and the Federal Bureau of Investigation have recently acquired surveillance drones from the Shenzhen-based company DJI, around the same time the Defense Department deemed products from the Chinese company to be a potential national security threat, according to an Axios report. DOBRIANSKY AND RUNDE: CHINA'S POWER INSIDE THE UN IS GROWING RAPIDLY AND US MUST UP ITS GAME Procurement records show that the Secret Service bought eight DJI drones on July 26 just three days after the Defense Department issued a statement warning about possible threats posed by the company's products. Around the same time, records show that the FBI bought 19 drones from DJI. DJI is one of the most popular drone manufacturers in the industry, and the company requires those who purchase their products to download proprietary software and provide to users their own mapping databases that have the potential to be monitored remotely. Concerns about the company's products being used to advance China's interests have been longstanding and include a 2017 statement from the Department of Homeland Security that claimed with "moderate confidence" that DJI was "providing U.S. critical infrastructure and law enforcement data to the Chinese government."

FDA authorizes AI-based software for prostate cancer detection


The FDA has authorized the marketing of Paige Prostate, an AI-based software platform to help pathologists identify prostate cancer when they review slide images from prostate biopsies.1 The standard biopsy review process involves the pathologist examining digitally scanned slide images from prostate biopsies to find areas that are suspicious for cancer. Paige Prostate provides a supplementary assessment of the image and locates the area with the highest probability of harboring cancer. The pathologist can then examine this specific area further if they did not identify it on their initial assessment. "Pathologists examine biopsies of tissue suspected for diseases, such as prostate cancer, every day. Identifying areas of concern on the biopsy image can help pathologists make a diagnosis that informs the appropriate treatment," Tim Stenzel, MD, PhD, director of the Office of In Vitro Diagnostics and Radiological Health in the FDA's Center for Devices and Radiological Health, stated in a press release.

Amid Skepticism, Biden Vows a New Era of Global Collaboration

The New Yorker

Joe Biden made his début at the elegant green-marble rostrum of the United Nations this week, as the coronavirus infected more than half a million people each day worldwide, as wildfires and floods aggravated by climate change ravaged the Earth, and as the U.S. struggled to prevent a new cold war with China. In lofty language, the President tried to redirect the world's focus away from the calamitous end to America's longest war, in Afghanistan, and a recent bust-up with its most longstanding ally, France. Just eight months into his Presidency, Biden is already trying to hit reset on his foreign policy. "I stand here today for the first time in twenty years with the United States not at war. We've turned the page," Biden told the chamber.

New Test Leverages Machine Learning to Diagnose and Predict Sepsis


Sepsis is a huge healthcare concern. "You take every single cancer and all the deaths due to every single cancer and you add them all up together. More people die from sepsis worldwide than that," said Bobby Reddy, Jr., CEO of Prenosis, in an interview with MD DI. And even if patients survive, they can have lifelong consequences. "Sepsis occurs when you have a very abnormal, unhealthy reaction to infection," Reddy said.

Time to regulate AI that interprets human emotions


During the pandemic, technology companies have been pitching their emotion-recognition software for monitoring workers and even children remotely. Take, for example, a system named 4 Little Trees. Developed in Hong Kong, the program claims to assess children's emotions while they do classwork. It maps facial features to assign each pupil's emotional state into a category such as happiness, sadness, anger, disgust, surprise and fear. It also gauges'motivation' and forecasts grades.

Air Force IG to investigate Kabul drone strike that killed 7 children

FOX News

The Air Force on Tuesday said Lt. Gen. Sami Said will lead a review of the investigation into the Kabul Aug. 29 drone strike that was intended for ISIS-K militants but actually killed 10 Afghan civilians, including seven children. "The secretary of the Air Force has directed Lt. Gen. Sam Said, the Department of the Air Force inspector general, to investigate the facts and circumstances relating to the civilian casualty event on Aug. 29, 2021, in Kabul, Afghanistan," the Air Force said in a statement. The announcement comes one day after Pentagon press secretary John Kirby told reporters that Defense Secretary Lloyd Austin ordered a senior-level review of the investigation that detailed the day's events. The investigation conducted by the U.S. Central Command found that the military mistakenly identified a white Toyota Corolla, believed to be carrying at least one Islamic State fighter, and instead was carrying a longtime Afghan employee at a U.S. humanitarian organization. The vehicle in question had been tracked for eight hours after initially being spotted in an Islamic State compound in Kabul.
