57001851c4 Trying to debug kernel parameters learning (fails even when noise fixed)
may be some instablility, seems like it can get it if it starts close

617d73ca32 Now checkgrads a lot more of the time, but still fails in optimisation, seems also odd that when parameter is fixed kernel parameters go to infinity 2013-06-26 15:44:26 +01:00
