| A popular method of calculating the value of a concept shows that the next value of C4 is determined by multiplying the current values of C1, C2, and C3 by their respective edge weights, E14, E24, and E34, and then summing the products. A normalizing function then "squashes" the sum into the range of valid concept values. Although this function is usually nonlinear and sigmoid, in this example, the normalizing function is linear and can be implemented with a weighted average. |
