DAfter waking up,you may feel frustrated that you cannot recall the dreamsyou had last night.Artificial Intelligence (AI)may be able to help.Previously,there have been AI models that can turn texts into images.Theydo this by leamning from a large amount of data from both texts and images.Thistime,researchers from Osaka University in Japan have trained an AI system calledStable Diffusion to recreate images directly based on people's brain scans,Sciencemagazine reported.The researchers used an online data set provided by the University ofMinnesota,which consisted of brain scans from four participants as they eachviewed a set of 10.000 photos.The scans were recorded by functional magneticresonance imaging fMRI,The AI then leamned about the participants'brainactivities by analyzing changes in blood flow shown by the fMRI data-when a partof the brain is activated,more blood will flow to it.It then matched the brainactivity with the photos.Through this method,the AI learned how human brainswould react when seeing different photos.Finally,the researchers tested the AI onadditional brain scans from the same participants when they viewed photos ofobjects.If the person looked at an airplane,for example,the AI would use the brainscan data to create an image of a very blurry (airplane.Then,it wouldturn on the previous "text-to-image"model and improve the quality of the imageby feeding itself the keyword "airplane"The final images were "convincing toabout 80 percent accuracy,according to the researchers.The new study created a novel approach that combines texts and images to"decode the brain".According to Ariel Goldstein from Princeton University,in thefuture,the technology can be used to record imagined thoughts and dreams orallow people to understand how differently other animals perceive (reality.32.What is Stable Diffusion meant to do?A.Scan people's brains.B.Turn texts into images.C.Use brain scans to rebuild images.D.Record relevant experimental data.33.How did the AI learn about the participants'brain activities?A.By analyzing changes in blood flowB.By asking the participants questionsC.By comparing different brain scansD.By referring to previous Al models34.What can we learn from the text?A.Dreams can hardly be forgotten by us.B.Texts and images help decode the brain.C.People's brains are affected by fMRI.D.The AI creates clear images of objects at first.英语试题第6页(共10页)
