Machine Learning Spotlight — Identifying Antibiotics: Researchers at MIT discovered a new antibiotic using deep learning. The antibiotic, known as halicin, works against a variety of bacteria, including those thought to be antibiotic-resistant. Researchers trained the machine learning model on a dataset of existing molecules that inhibit E. coli growth, then asked it to predict which of 6,000 different molecules would prove effective against E. coli. From the results, researchers selected candidates for testing and discovered a strong antibiotic in halicin, a molecule originally identified for diabetes treatment. Experts believe this methodology could apply to a wide range of drug discoveries beyond antibiotics.
U.S. Chief Technology Officer Criticizes EU’s Approach to AI Regulation: Chief Technology Officer of the United States Michael Kratsios critiqued the European Union’s AI regulation strategy in an interview with The Wall Street Journal. The EU should be “spending as much time on investing in these technologies as they are in drafting white papers,” he stated, characterizing the EU’s investment in AI as “very small.” Kratsios said the recently released European Commission’s White Paper on AI “clumsily attempts” to categorize all AI technology as either high or low risk; he called instead for a more nuanced spectrum.
