Beginning Anomaly Detection Using

X and the weight vector W. X represents the input data, and W represents the 

list of weights that this node carries to multiply with the input vector. Recall that the 

dot product is when each element in the vector is multiplied with the corresponding 

element in the second vector, as in Figure 

3-4

.

Both are different ways to represent a vector, although the second method is ideal 

considering your data and weights would most likely take the shape of a matrix.

After that, there is an optional bias function where the value
