BayesFluxR (version 0.1.3)

likelihood.seqtoone_tdist: Use a T-likelihood for a seq-to-one recurrent network.

Description

See likelihood.seqtoone_normal and likelihood.feedforward_tdist for details,

Usage

likelihood.seqtoone_tdist(chain, sig_prior, nu = 30)

Value

see likelihood.feedforward_normal

Arguments

chain

Network structure obtained using link{Chain}

sig_prior

A prior distribution for sigma defined using Gamma, link{InverGamma}, Truncated, Normal

nu

DF of TDist

Examples

if (FALSE) {
  ## Needs previous call to `BayesFluxR_setup` which is time
  ## consuming and requires Julia and BayesFlux.jl
  BayesFluxR_setup(installJulia=TRUE, seed=123)
  net <- Chain(RNN(5, 1))
  like <- likelihood.seqtoone_tdist(net, Gamma(2.0, 0.5), nu=5)
  prior <- prior.gaussian(net, 0.5)
  init <- initialise.allsame(Normal(0, 0.5), like, prior)
  x <- array(rnorm(5*100*10), dim=c(10,5,100))
  y <- rnorm(100)
  bnn <- BNN(x, y, like, prior, init)
  BNN.totparams(bnn)
