The previous set of experiments suggested returning to translation one scale was 'fixed'. The effects were investigated by performing 6 stages: translation, scaling, translation, scaling, translation and finally scaling.
The results appear very interesting.
After the first 2 iterations, which is what normally gets done, improvement continue to be made. These improvements are quite significant too.
To find out how long such improvements can be made, a long such experiment
was performed, namely:
Same as above, but 18 stages rather than just 6. The result is very
interesting to look at. Improvement are made during the first 4 iterations
or so and then the brain 'wobbles' between two states (optimal scale
versus optimal translation). It still seems that before that stage
of 'wobbling', actual improvements are made. It was decided to try
the same procedure on two completely different brain data which leads
to the next experiment.
Two very different brains were chosen. In this case, after the first 2 stages, the 'wobbling' state was reached. This would imply that optimising translation and scale 'together' might not always be helpful.
