[sage-support] possible bug in DiscreteHiddenMarkovModel - NaN produced in output matrices

2014-05-08 Thread Jesse Hersch
Hi there, I think I may have found a bug in the class hmm.DiscreteHiddenMarkovModel. The repro is below. It probably has something to do with one emission value being much more common than the others, but that shouldn't be invalid from my understanding of HMMs. I am running Sage Version 6.2

[sage-support] reflexive @interact controls (control values update)

2014-05-08 Thread Pedro Cruz
Is possible that after user action on interaction control X the function that updates the "interact screen" could also update the X control possible values ? Thank you, Pedro -- You received this message because you are subscribed to the Google Groups "sage-support" group. To unsubscribe fro

Hi Martin, danke für die schnelle Rückmeldung. So wie es scheint basiert der Test auf DDF, was vermutlich langsamer ist im Vergleich zu Rabins Test wenn grad(f) = p = prim. Im allgemeinen Fall aber die schnellere Variante. Danke nochmal, viele Grüße Am Mittwoch, 7. Mai 2014 15:35:45 UTC+2 s
