LBFGS not working (?) #126

Closed geospith closed 9 years ago

geospith commented 10 years ago

Batch optimisation with LBFGS runs, but returns nonsense results.

riedelcastro commented 10 years ago

How many iterations were run? Did it run to convergence? How does the objective grow/shrink?

rockt commented 10 years ago

I have the same problem in MF and I think it might be that LBFGS needs a different way of creating examples!?

riedelcastro commented 10 years ago

Oddly LBFGS works in OptimizeByLearningSpecs.

riedelcastro commented 9 years ago

Currently we don't use factorie optimization anymore. We could think about our own LBFGS implementation, but for now we can live with adagrad I think.
