function K = tabular_kernel(fg, self) % TABULAR_KERNEL Make a table-based local kernel (discrete potential) % K = tabular_kernel(fg, self) % % fg is a factor graph % self is the number of a representative domain % % Use 'set_params_kernel' to adjust the following fields % table - a q[1]xq[2]x... array, where q[i] is the number of values for i'th node % in this domain [default: random values from [0,1], which need not sum to 1] if nargin==0 % This occurs if we are trying to load an object from a file. K = init_fields; K = class(K, 'tabular_kernel'); return; elseif isa(fg, 'tabular_kernel') % This might occur if we are copying an object. K = fg; return; end K = init_fields; ns = fg.node_sizes; dom = fg.doms{self}; % we don't store the actual domain since it may vary due to parameter tieing K.sz = ns(dom); K.table = myrand(K.sz); K = class(K, 'tabular_kernel'); %%%%%%% function K = init_fields() % This ensures we define the fields in the same order % no matter whether we load an object from a file, % or create it from scratch. (Matlab requires this.) K.table = []; K.sz = [];
