Julián Castro has gotten a few things from his mother: a last name, a twin brother, a general sense of optimism, and a penchant for serving his community. Maria del Rosario Castro, a now 79-year-old Mexican American activist, was once a member of La Raza Unida, a prominent Chicano political party in Texas.

This paper introduces the use of per-class regularization hyperparameters in Gabriel graph-based binary classifiers. We demonstrate how the quality index used for regularization behaves both in the margin region and in the presence of outliers, and how incorporating this regularization flexibility can lead to solutions that effectively eliminate outliers while training the classifier. We also show how it can address class imbalance by generating higher and lower thresholds for the majority and minority classes, respectively. Thus, rather than having a single solution based on fixed thresholds, flexible thresholds expand the solution space and can be optimized through hyperparameter tuning algorithms. Friedman test shows that flexible thresholds are capable of improving Gabriel graph-based classifiers.

Hondurans are heading to the polls to elect a new president in a tightly contested race that is taking place amid concerns over voter fraud in the impoverished Central American country. Polls opened on Sunday at 7am local time (13:00 GMT) for 10 hours of voting, with the first results expected late Sunday night. The elections, in which the 128 members of Congress, hundreds of mayors, and thousands of other public officials will also be chosen, are taking place in a highly polarised climate, with the three top candidates accusing each other of plotting fraud. Moncada has suggested that she will not recognise the official results. Incumbent President Xiomara Castro of the LIBRE party is limited by law to one term in office.

The last decade has seen an upswing in interest and adoption of reinforcement learning (RL) techniques, in large part due to its demonstrated capabilities at performing certain tasks at "super-human levels". This has incentivized the community to prioritize research that demonstrates RL agent performance, often at the expense of research aimed at understanding their learning dynamics. Performance-focused research runs the risk of overfitting on academic benchmarks -- thereby rendering them less useful -- which can make it difficult to transfer proposed techniques to novel problems. Further, it implicitly diminishes work that does not push the performance-frontier, but aims at improving our understanding of these techniques. This paper argues two points: (i) RL research should stop focusing solely on demonstrating agent capabilities, and focus more on advancing the science and understanding of reinforcement learning; and (ii) we need to be more precise on how our benchmarks map to the underlying mathematical formalisms. We use the popular Arcade Learning Environment (ALE; Bellemare et al., 2013) as an example of a benchmark that, despite being increasingly considered "saturated", can be effectively used for developing this understanding, and facilitating the deployment of RL techniques in impactful real-world problems.

Fox News anchor Bret Baier has the latest on the Murdoch Children's Research Institute's partnership with the Gladstone Institutes for the'Decoding Broken Hearts' initiative on'Special Report.' The benefits of artificial intelligence (AI) in the medical space are ever-growing, but evidence suggests it can also come with risks. A new study by European researchers investigated how AI can change the behavior of endoscopists when conducting a colonoscopy, and how their performance dips when not using AI. The research followed clinicians at four endoscopy centers in Poland participating in the ACCEPT (Artificial Intelligence in Colonoscopy for Cancer Prevention) trial, where AI tools for polyp detection were introduced at the end of 2021. Colonoscopies at these centers were randomly selected to be administered with or without AI assistance.

'The CyberGuy' Kurt Knutsson joins'Fox & Friends Weekend' to discuss the potential effects of artificial intelligence software like ChatGPT on the brain. Using ChatGPT on a long-term basis could have negative effects on brain function. That's according to a study led by the Massachusetts Institute of Technology (MIT), which found that using a large language model (LLM) to write multiple essays over a four-month period could hamper cognitive abilities. In the study, 54 participants were divided into three groups. One group used ChatGPT, an LLM product made by OpenAI, to write an essay.

Fox News anchor Bret Baier has the latest on the Murdoch Children's Research Institute's partnership with the Gladstone Institutes for the'Decoding Broken Hearts' initiative on'Special Report.' A simple selfie could hold hidden clues to one's biological age -- and even how long they'll live. That's according to researchers from Mass General Brigham, who developed a deep-learning algorithm called FaceAge. Using a photo of someone's face, the artificial intelligence tool generates predictions of the subject's biological age, which is the rate at which they are aging as opposed to their chronological age. FaceAge also predicts survival outcomes for people with cancer, according to a press release from MGB.

The first fully human-capable AI agents for healthcare are now being used across the country. Artificial intelligence is gaining more of parents' trust than actual doctors. That's according to a new study from the University of Kansas Life Span Institute, which found that parents seeking information on their children's health are turning to AI more than human health care professionals. The research, published in the Journal of Pediatric Psychology, also revealed that parents rate AI-generated text as "credible, moral and trustworthy." More than 100 parents ranging from 18 to 65 years old were asked to rate text generated by either a human doctor or ChatGPT (the AI chatbot made by OpenAI) under the supervision of an expert.

'The Five' co-hosts discus Elon Musk's prediction that jobs will become like a'hobby' as AI progresses. Elon Musk is urging people to submit their medical scans to Grok for analysis, but doctors advise using caution when relying on artificial intelligence for health care insights. The Tesla and SpaceX CEO posted on X on Tuesday, encouraging his followers to submit X-rays, PET scans, MRIs or other medical images to the AI chatbot. "This is still early stage, but it is already quite accurate and will become extremely good," Musk wrote. WHAT IS ARTIFICIAL INTELLIGENCE (AI)?
