Researchers found that larger fish shoals become more accurate and faster at detecting real threats and distinguishing them from harmless disturbances. The findings suggest that large animal collectives can overcome trade-offs between speed and accuracy, and may operate under a state of criticality, optimizing information flow.
A team of scientists from the SETI Institute and UC Davis documented humpback whales producing large bubble rings during friendly interactions with humans. This behavior may offer insights into nonhuman intelligence and aid in the search for extraterrestrial life.
Researchers used machine learning to predict multiple types of intelligence from brain connections, with general intelligence performing best. The model's accuracy improved when trained on theory-driven connections, suggesting there are still unknown aspects of intelligence to discover.
A study published in Science China: Information Sciences found that crowdsourcing can help improve label quality and reduce costs. Researchers analyzed worker performance and provided criteria for evaluating their qualities, enabling the elimination of low-quality workers from the crowd.
