Update of Incoming Weights

$$W_{I.j}(t+1) = W_{I.j}(t) + \eta1(I- W_{I.j}(t))$$ (8.10)

The weight vector $W_{I.j}$ at $t+1$ is the result of the summation of the weight vector $W_{I.j}$ at $t$ and the product of the learning constant $\eta1$ with the difference vector of the input vector $I$ and the weight vector $W_{I.j}$ at time $t$.
