    Hasn't this been the case for a while? I vaguely remember using the optimal e8 packing to try to get denser product quantization for vector embeddings.

      She proved it

      How did you apply e8 to vector embeddings?

      • Scene_Cast2 2 days ago ago

        Chunk up your 128D embedding into 16 8D pieces, then quantize using the optimal packing points. Performs worse than k-means in my experience.

          Why is this downvoted? I think it is sincere.

    I always think its funny when someone says "I am a chair" and really means it

      I think it technically means they have a permanent endowed position.

        Reminds me of an old 1990s/2000s post from News of the Weird [0] about endowed chairs with funny names, such as an XYZ Corn Chair at some midwestern US university, or an NEC/ Nippon Electric Chair at some Japanese university.

    Thank god i need to go rearrange the 8 dimensional cannonballs in the trunk of my car

      Sphere packing in higher dimensions actually has some applications, for example in signal processing.
