## New ideas (just to record some new ideas)
I have an idea to improve tokenization. We can hardcode some channels to have meanings. Example:
Channel 0 = "space"
Channel 1 = "capitalize first letter"
Channel 2 = "capitalize all letters"
Therefore:
Embedding of "abc": [0, 0, 0, x0, x1, x2 , ..]
Embedding of " abc": [1, 0, 0, x0, x1, x2, ..]
Embedding of " Abc": [1, 1, 0, x0, x1, x2, ..]
Embedding of "ABC": [0, 0, 1, x0, x1, x2, ...]
......
so they will share most of the embedding. And we can rapidly compute the output probability of all variations of "abc".
Note: the above method is assuming that p(" xyz") / p("xyz") is the same for any "xyz", which can be wrong.
Better: define emb_space emb_capitalize_first emb_capitalize_all to be a function of emb.
Maybe the Best: let 'abc' ' abc' etc. to share the last 90% of their embeddings.
At this moment, all our tokenizers spend too many items to represent all variations of 'abc' ' abc' ' Abc' etc. Moreover the model cannot discover that these are actually similar if some of these variations are rare in the dataset. My method can solve this. I plan to test this in a new version of RWKV.
## Quick start
Use https://github.com/BlinkDL/RWKV-LM/tree/main/RWKV-v4neo (latest code, compatible with v4).

## How it works
RWKV is inspired by Apple's AFT (https://arxiv.org/abs/2105.14103).
