摘要
In many real-world systems, 資訊 can be transmitted in two qualitatively different ways: by copying or by transformation. Copying occurs when messages are transmitted without modification, e.g. when an offspring receives an unaltered copy of a gene from its parent. Transformation occurs when messages are modified systematically during 傳播, e.g. when 突變al biases occur during 遺傳 replication. Standard 資訊-theoretic measures do not distinguish these two modes of 資訊 transfer, although they may reflect different mechanisms and have different functional consequences. Starting from a few simple axioms, we derive a decomposition of mutual 資訊 into the 資訊 transmitted by copying versus the 資訊 transmitted by transformation. We begin with a decomposition that applies when the source and destination of the c
