Ross indexed the following pages under the keyword: "Feedback".
Feedback of the simple concept
Summary: The concept of "negative feedback" is just too simple to be worth anything. (See also
Summary: Evidence that neurons learn and then "fix". Feedback binary counter turned to decimal
Summary: An extremely simple example of feedback modifying behavior. ( See 2729)
Summary: If systems are joined by dominance, the latent roots are unmoved.
Summary: Two possible ways of proving feedback between two sub-systems. Feedback is also proved present if we can find in A a single frequency not found in A + B. Feedback test for
Arc needs no feedback Cortex needs no feedback Feedback not in cortex
Summary: The nervous system should not have internal feedbacks (unless for special reasons) But see 3396. Confirm 3425, 3521
Summary: Of the resting states, the number stable can be anything from none to all.
Feedback destroying information Transducer in a ring
Feedback in information amplifier
Summary: Evolution and the homeostat are information-amplifiers. ( 3616)
Discrimination is it a problem? Feedback discriminative
Summary: The "problem" of discriminative feedback must be shown to exist in the real environment.
Discrimination feedback for discimination Feedback third order
Summary: All necessary improvements to the basic ultrastable system can be had by the addition
of further orders of feedback. Chess organisation for
Summary: Train by situations so matched to the system's present ability that feedbacks of "right"
or "wrong" are equally likely. Feedback of full efficiency
Summary: There is no general machine that can be specialised, only a class of individual machines.
It is the class that can be broad or narrow. 5507 Machine no general machine, only class
Summary: How fast information decays when passed through a number of variables at random. 5381
Summary: If a system is affected, with feedback by another, each can be regarded as a transducer
with separated input and output (= conceptual uncoupling). 5428 Feedback conceptual severance
Summary: "Thinking things over" in a multistable system. Discriminative feedback requires mere
opportunism. 5549, 5584, 5601 Discrimination requires information Feedback discriminative needs information
Selection requires information
Summary: No general principle can be sufficient guide when selection must be done; some actual
channel is also necessary. 5585 Arc selection of Essential variables discrimination by Feedback methods for discrimination
Summary: Every system with feedback is equivalent to a chain of systems without feedback. Feedback equivalent net without
