Implicit mixtures of Conditional Restricted Boltzmann Machines

Implicit mixtures of Conditional Restricted Boltzmann Machines代码，主要是为了分析实值RBM

function [fexphidinp] = crbmfe（datavishideffhidbiaseffvisbias）

%data is the current setting of the visible variables
%if there are multiple rows we return free energy for each row
%returns free energy （negative log probability）
%also returns exphidinp so we don‘t need to call exp again
%（e.g. for computing sigmoid）
[numcasesnumdims] = size（data）;

mismatch = data - effvisbias;
visterm = sum（mismatch.^22）/2; %sum over dimensions assume sd is 1

%Term calculated by summing over hiddens
hidinp = data*vishid + effhidbias;
exphidinp = exp（hidinp）; %cache this computation
hidterm = log（1 + exphidinp）;
hidterm = sum（hidterm2）; %sum over hiddens

f = visterm - hidterm;

% %now for the gradients with respect to each dim of visible

% poshidprobs = 1./（1 + exp（-hidinp））;
% topdown = w‘*poshidprobs; %total input from hiddens to each unit

% df = mismatch - topdown;
