APC News

Great news!
TC-RAG, the latest research involving a Gewu Society member, achieved a score of 87.95 on medical postgraduate entrance-exam questions, making it the strongest Chinese-language medical model currently available.
TC-RAG uses a stack to simulate an LLM’s memory, allowing information to be pushed and popped. It is the first Turing-complete RAG system. Two meta-actions, push and pop, simulate a Turing machine and can be combined into more complex actions: summarization pops and then pushes, reflection pops, and tool observation pushes. This helps the language model use RAG more effectively and manage its memory more efficiently.

Not sure what to do over the break? Looking for a challenge to shake up an otherwise quiet routine?
Introducing the Gewu Society/APC 2024 Summer Recruitment Event! Starting at eight tonight, you will have one set of papers, eight subjects, and five days to find your moment to shine this summer.
Everyone who takes an exam receives a Gewu Society 8th-anniversary commemorative keychain. After the event, anyone who passes may choose one gift from the 8th-anniversary prize pool, which currently includes a cup, folder, or shirt (๑❛ᴗ❛๑).

Mathematics examiner: It really isn’t that hard this time. (There is only one question, the examiner kindly supplies the prerequisite knowledge, and you can spend up to 300 minutes on it!
Geography examiner: Mine is the easiest. (Only ten questions, and it takes just 30 minutes!
History has only two questions, and it is open-book! (A hint from the history examiner: review the three Abrahamic religions; both questions are about religion.
Biology examiner: Biology is going to be a delight this time. (And it is open-book!
Chemistry examiner: Good news: every chemistry multiple-choice question may have more than one correct answer this year!
Astronomy examiner: This is our easiest and most entertaining astronomy paper in years!
Mysticism examiner: All conditioned phenomena are like dreams, illusions, bubbles, or shadows; like drops of dew or flashes of lightning. Thus should they be contemplated.

Here is this year’s logo! Thank you all for your continued support. We truly appreciate every one of you!

Happy Lunar New Year! A-kun has more good news to share as the new year begins.
Zhang Wentao and Jiang Xinke, APC members at Wuxi Smart Deep Insight Technology Co., Ltd., have worked with researchers from MIT, University College London, the Chinese Academy of Sciences, and other institutions on supply-chain management and allocation. Their Deep Black-Litterman Model (DBLM) brings a financial model into supply-chain management and uses spatiotemporal graph neural networks to optimize order-allocation strategies automatically, improving supply efficiency. The work has been submitted to a leading deep-learning conference, and the paper is available on arXiv. We look forward to advancing innovation in supply-chain management together with researchers and practitioners everywhere! /sparkle
Congratulations to both APC members!

The Chronicles of Narnia: Tianjin Edition—Tales of the Hai River
“The stairs in my house lead straight to the Galápagos Islands. I can collect specimens without even going outside.”
“Well, imagine that! My front door opens onto the Hai River. I can jump off the balcony for a swim, then come back up and make Eight-Treasure Tofu!”
“Now that’s convenient cooking. But how do you get to work?”
“Work, shmerk. Just enjoy yourself. Speaking of which, how do you cook? There’s nothing at all where you live!”
“Cook? What is cooking?”
“Forget I asked. My mistake!”

I reshot Darwin mainly because I was not satisfied with the studio or characterization from '19. I entered the cosplay community in 2017 and finally completed this shoot in 2023. Somehow, 7 years have passed along the way. The Darwin shoot from 2019 still feels vivid, although some of the friends from that time have since disappeared into the crowd. I am 25 now. I have cosplayed every character I wanted to, and this year I hope to move into science communication. Wish me luck, and happy birthday to me. Thank you to everyone who provided props. Meeting people is a matter of fate; becoming friends is a blessing. I hope you enjoy this year’s finished set!
