likelihood.seqtoone_normal {BayesFluxR}  R Documentation 
Use a Normal likelihood for a seqtoone recurrent network
Description
This creates a likelihood of the form
y_i \sim Normal(net(x_i), \sigma), i=1,...,N
Here x_i
is a subsequence which will be fed through the recurrent
network to obtain the final output net(x_i) = \hat{y}_i
. Thus, if
one has a single time series, and splits the single time series into subsequences
of length K which are then used to predict the next output of the time series, then
each x_i
consists of K consecutive observations of the time series. In a sense
one constraints the maximum memory length of the network this way.
Usage
likelihood.seqtoone_normal(chain, sig_prior)
Arguments
chain 
Network structure obtained using 
sig_prior 
A prior distribution for sigma defined using

Value
see likelihood.feedforward_normal
