The first thing to note is that we will be satisfied with approximate inference methods, even if they do not provide bounds on the quality of the approximation — we will be able to judge if we are doing well enough based on how well the system answers queries. The major approaches to approximate inf ...

For each point of a cluster, the neighbourhood of a given radius has to contain at least a minimum number of points, which is, the density in the neighbourhood has to exceed some predefined threshold. This algorithm needs three input parameters, which comprised of the neighbour list size, the radius ...

The Sum is Greater than the Parts: Ensembling
... The sum of squared residuals (SSR) is minimized. For BKT-BF, the values for Guess and Slip are bounded in order to avoid the “model degeneracy” problems that arise when performance parameter estimates rise above 0.5 [Baker et al. 2008]. For BKT-EM the parameters were unbounded and initial parameters ...
