Byte bigram from first 1024 bytes of enwik9 — Ea × Eb joint event table
What is the LPP?
The Log Product Pattern is the core data structure of the Universal Model. Each entry c(ea, eb) records how often context event ea co-occurred with output event eb. Log support = log2(count).
Ea — context bytes (30)
Eb — output bytes (30)
Lines: joint events
Opacity ∝ log support
