[R-sig-Geo] Help regarding Autoencoder

[Subir Paul]

Dear All,
I was using "SAENET" package for autoencoding.
I used the following code:
h=SAENET.train(data[,1:200], n.nodes = c(100, 20), unit.type =
("logistic"), lambda = 0.001,
               beta = 0.0001, rho = 0.01, epsilon = 0.01, optim.method =
c("BFGS"),
               rel.tol=sqrt(.Machine$double.eps), max.iterations = 1000)
But its showing the error:
Error in optim(par = theta, fn = J.theta, gr = grad.theta.J, method =
optimizer,  :
  initial value in 'vmmin' is not finite

Can anyone help me regarding this issue?

Thanks in advance.
