<p></p> <p><b>New page</b></p><div>{{PHYS380-2011}}<br /> <br /> In this block, we have shown that<br /> *Maximization of the input-output mutual information, in its various forms, leads immediately to adaptation, as a mechanism for efficient coding of the signal<br /> *We have introduces two general types of adaptation --adapting to the mean of the signal and to its variance.<br /> *Adaptation to the mean, including a perfect adaptation, can be achieved by negative feedback loops.<br /> *We have discussed that if the responses need to be developed in a short time, without waiting for very long, then there is also adaptation of the time scales, the third type of adaptation.<br /> *We have emphasized that many cognitive phenomena, such as learning, can also be interpreted as information processing and adaptation.<br /> *We have read the papers that show that biological systems show all these different forms of adaptation.</div>
