vectorrain··on Dense Vector and Sparse Vector and Fulltext and Tensor Reranker = Best for RAG?
What are the advantages and potential challenges of combining dense vectors, sparse vectors, and full-text search in a hybrid retrieval method, as implemented in Infinity v0.2, and how does this approach compare to traditional vector search or other retrieval methods?

Yes, I agree. It seems each Chinese company has a secret relationship with the Chinese government. But what they didn't notice is that the American embassy would censor your social account and content when you apply for Visa. American is the biggest surveillance country but takes it for granted.

"That China has everyone's face 3D scanned by now (multiple photos from multiple angles), everyone's voiceprint, everyone's IP, transcripts of what was said and by who" As a native Chinese, I haven't been scanned by 3D scanner. How do you get this conclusion?

I don't know why symmetries related with physics or Lagrangian of the system? Could you give me more specific instructions or some reading materials?

Why don't you learn more about "Prism Event"?

Nonsense! If a deal hasn't been made, each side could change their mind, right? If we want to make a deal and I take great advantages on you, is it right for me to accuse you if you regrete before the deal is made?

"because Chinese developers tend to "take take take" and not contribute anything back, ever." It's not ture. For example, Siggraph is the best conference in the computer graphics field. In 2018, the number of papers that contain Chinese or ethnic Chinese is 45%.

Besides, many Chines and ethnic Chinese reasearchers are active in many frontier technology filed such as AI and Computer Vision field.

The acadimic and industry status and constribution of Chines reashers/company are increasing rapidlly.

vectorrain··on Huawei Facts: An open letter to the US media
But this time, it's US that impose restrictions on Huawei. That is your so called free market?
vectorrain··on Game Loop
Fair enough. I think I didn't understand the difference between game time and real time before. I though the running time of "display_game()" was the game time (curr_frame_tick - prev_frame_tick). Thanks a lot for your detailed explanation.

The sconed part "Game Speed dependent on Variable FPS". I'm confused about the parameter of function "update_game()". From the code, I think the time length of "curr_frame_tick - prev_frame_tick" would increase at each timestep beacause of function "display_game()".

When I google "game loop", I found deWiTTERS Game Loop, http://www.koonsolo.com/news/dewitters-gameloop/ which I still not fully understand.
