Question : An artificial neuron with linear activation function, two inputs and a bias is
trained using the rules:
if belongs to class and the transpose of multiplied
with is less than or equal to zero;
if belongs to class and the transpose of multiplied
with is greater or equal to zero;
otherwise.
In the above expressions, is the weight vector, denotes iterations, and is the feature vector
as shown in the following table:
All weights are zero at the start, ie where indicates the transpose of the
vector, the first zero element in this vector is the initial weight of the first input the second
zero is the initial weight of the second input and the last zero element in this vector is the
weight of the bias term, which always receives an input equal to The neuron is trained by
feeding input vectors in the order presented in the table, ie For example, starting
from the top, at the first input pattern is and the correct classification for this input
vector is "class
Q What would the weights be after the presentation of each one of the input patterns?
