According to the report, the signal map of the suspected pulsar FAST\u00a0We're generating over 30 million a week.<\/strong>In the early days, even with specialized software in the field of astronomy, 1 terabyte of data took more than 10 days to process, even with 24-hour work.

Early in the collaboration, the project team designed aAI solutions based on multimodal + semi-supervised learning<\/strong>AI will continuously and deeply \"self-learning\" astronomical knowledge, after receiving the original signal, without manual labeling, AI will first use astronomical knowledge to prejudge and screen, automatically construct effective information in large-scale data, and finally make manual comparison.<\/p>\n

In this way.More than 120 times faster processing of FAST data<\/strong>AI can do it in less than 3 days. What used to take a year to process manually, AI can do in less than three days.False alarms have also decreased 98%<\/strong>.<\/p>\n

In the past year, Tencent Youtu Lab has designed an end-to-end algorithm model FastSearch, which completely abandons the filtering noise, Fourier transform, and other astronomical professional processing and complex annotation of the original signal, which is equivalent to the absence of a \"middleman\" and saves a lot of arithmetic power and time.<\/p>\n

1AI has learned that with this model, the signal processing efficiency is 15 times higher than the AI model at the beginning of the collaboration.Hundreds of times better than pre-2021 processing methods<\/strong>The speed at which the Eye of Heaven captures cosmic signals has already failed to keep up with the speed at which AI \"sees\".
