So option A is the best possible answer.
Because they were surrounded. they were surrounded even at the Chesapeake bay.
Answer:
<em>Biological Basis of Learning:
</em>
<em>Hebb's Rule</em>
Explanation:
<em>The rule of Hebb is a postulate which Donald Hebb proposed in 1949.</em>
<em>It is a law of learning that explains how neuronal behaviors affect the neuronal relation, i.e., synaptic plasticity. It offers an algorithm for updating neural relation weight within the neural network.</em>
Hebb's rule offers a simplified model, based on physiology to imitate the activity-dependent characteristics of synaptic plasticity and has already been extensively used in the artificial neural network area.
Various versions of the rule were proposed to make updating law more practical.
