Learning II 。Encoding: A system learns a pattern if the system encodes the pattern in its structure. 。 Change: A system learns or adapts or "self -organizes"when sample data changes system paramefers. Quantization A system learns only a small proportion of all patterns in the sampled environment
Learning • Encoding: A system learns a pattern if the system encodes the pattern in its structure. • Change: A system learns or adapts or “self -organizes” when sample data changes system parameters. • Quantization A system learns only a small proportion of all patterns in the sampled pattern environment
