FIG. 2.

First 3 outer loops of BiSNN-Walk on mouse embryo data set. Outer loop 1 has three inner loops. On the first inner loop, our initial cluster contains nine fibroblast cells and one mid-blastocyst cell. Notice that on the second inner loop, the mid-blastocyst is removed from the cell, and we obtain the cleaned stable cluster on our third inner loop. The second outer loop also contains three inner loops. On the first inner loop, we obtain our initial cluster of seven early-2-cell-stage cells and one 16-cell-stage cell. On the second inner loop, the 16-cell-stage cell was removed, and the zygotes, which are much closer in developmental to early-2-cell stage, are added. On the third inner loop, we obtain the cleaned stable cluster. A similar self-correcting behavior can be seen in the third outer loop.
