Hi Jean-Eric!



 Jean-Eric_Campagne:

But my point is that switching seed 1 to 2, destroy completly the generalisation power. So, you point that some network training are unstable.


You might also try seeding the random-number generators with
3, 4, and 5 (and just in case there is something funny about how
the seeds work – which I strongly doubt – with 314158, 314159,
and 314160, as well).
Can you characterize the goodness of your results with a single
statistic?  It would be interesting to see that statistic for a number
of different seeds.
Good luck.
