replaces words in stdin at random with other words occurring in the same 1-word context window—sort of a minimalist word vector similarity replacement
@er1n In this case it looks to me like @aparrish means something like, if the text has phrases like "a fine plan" and "a strange plan", then any use of "a […] plan" could have the middle word replaced by either "fine" or "strange" at random. So it's the context a word appears in, where context is determined by looking one word before and one word after.
@er1n@aparrish yeah, that's my reading of that Python anyway. although it's not precisely "swapping" since each instance of a context can be replaced with any other instance, including itself; in very unlikely circumstances all instances could be replaced by the same word every time.
@aparrish btw this is an astonishingly compact implementation and I think it's super cool that you can do interesting generative text so succinctly! (cc @er1n)
@aparrish what does "one-word context window" mean
