April 1 News.Alibaba CloudToday's post says that following the big model access to astronomical telescopeNational Astronomical ObservatoryOnce again, we have joined forces with Aliyun to release the first internationalLarge model of the sun -- "Golden Crow". The model is said to be based onThousand Questions on Tongyiseries of open-source models that are currently more accurate than 91% at forecasting solar flares at the M5 level.Highest level of solar forecasting at this level.
Note: Solar flares are usually categorized into five levels: A, B, C, M and X. When a solar flare erupts, a large number of charged high-energy particles attack the Earth's electromagnetic environment, which in severe cases can cause widespread power outages around the globe, damage to in-orbit satellites, and threaten the safety of space stations, etc. (A medium-intensity M5-level flare can have a significant impact on the Earth's space environment). Therefore, accurate forecasting of solar activity is of great significance in safeguarding space security.
With the increase in the number of solar observation satellites and the development of space exploration technology, solar observation data show an exponential growth trend, and the past forecasting method that mainly relies on astronomers' manual interpretation of solar magnetic field images is difficult to deal with the huge amount of observation data in the present solar forecasting. Artificial IntelligenceSpecialized in handling multimodal data such as images, with the ability to understand and reason about complex physical relationships, is more applicable to solar forecasting.
It is reported that, based on models such as Qwen-VL, the "Jinwu" solar model completes fine-tuning training with more than 900,000 solar satellite images as samples. By inputting the solar physical parameters and corresponding observation images of the last time period, the "Golden Crow" solar model was trained with more than 900,000 solar satellite images for fine-tuning."The Golden Crow predicts flares for the next 24 hours.The "Golden Crow" can infer the physical parameters of the next time period by calling the diffusion model. At the same time, the "Golden Crow" can infer the physical parameters of the next time period, and generate a simulated image of the sun for the next time period by calling the diffusion model.
