Partially fixing numerical underflow for mixture models

In a mixture model the probability of an event \(x\) is written \(P(x=X) =\sum_{i}\pi_{i}P_{i}(x=X) \), where \(\pi_{i}\) is the probability of the point belonging to mixture \(i\) and \(P_{i}(x=X) \) is the probability of the event \(x=X\) in the \(i\)-th mixture. The problem is usually that the \(P_i\) are small which makes underflow happen when […]
