Algorithm 3.

(Associative) SOINN+ Node Merging

1: WT(b) ← WT(b) + 1

2: (A-SOINN+):

w_{b} \leftarrow w_{b} + ϵ_{b} \cdot \frac{x (t) - w_{b}}{W T (b)}

// Update BMU's weight vector (Equation 3).

3: for i in N_b do

w_{i} \leftarrow w_{i} + ϵ_{n} \cdot \frac{x (t) - w_{i}}{W T (i)}

// Update the neighbors of b (Equation 4).

5: end for

6: IT(b) ← 0 // Set the idle time of the BMU to zero.
