A study predicts that the energy consumption of the AI industry could match that of the Netherlands by 2027. However, if AI growth slows, its environmental impact may be less severe. The study’s projections consider factors like current AI growth rate and chip availability. The findings are considered speculative, but evidence from Microsoft suggests significant…
Large Language Models (LLMs) like ChatGPT have gained popularity for their human-imitating capabilities in tasks like question answering, text summarization, and language translation. However, the extent to which these models truly understand the underlying data-generating process has been questioned. Recent research from MIT has found that LLMs learn structured representations of space and time, indicating…
Researchers from MIT have developed a guardian system that improves the safety and performance of autonomous aircraft. The system uses visual attention to monitor both the pilot and itself during flight, and intervenes if attention discrepancies exceed predefined thresholds. In simulated scenarios, the collision rate dropped from 46% without the guardian system to just 23%…
