Different results between jaxopt.LBFGS and jaxopt.ScipyMinimize(method - 'l-bfgs-b')

7

I am trying to run a complex nonlinear optimization on a multi-dimensional data using vmap on the solver.run. Since I could not use the l-bfgs-b method in the ScipyMinimize wrapper,...

Passing a custom callback to jaxopt.ScipyMinimize

1

I would like to ask if there is any way to pass a custom call back function to one of the solvers (TNC) in this case. For example, I am...

I have been thinking about this my idea, might sound stupid: I have a circuit (called randles circuit), whose impedance is defined by the function: ``` def randles(p, f): s...

Output the hess_inv from bfgs using the Optimizer API

1

Hi Reuben, I would like to ask if it is possible to extract the hessian_inv from BFGS using the Optimizer API (Minimizer) as is possible with the functional API?

Hi rfeinman, I want to thank you for this incredible package. I especially like the fact that I can pass in a custom call back function to minimize. I would...

discrepancies in values of the jacobian

2

I tried to compare the values obtained from computing the jacobian of a complex valued function using numdifftools and found that it differed from that computed using autograd only for...

Overflow encountered with tanh and coth functions

2

Hi, I work with impedance spectroscopy and I sometimes have to deal with large complex numbers. I have experience NaN results. I think the mathjs tanh implementation has an overflow...

Hi, I work with impedance spectroscopy and I sometimes have to deal with large complex numbers. I experienced some overflow issues with the mathjs tanh implementation which I do not...
