... or n H ≤ 2. This intuitively sensible prediction results from the fact that the Bayesian approach is sensitive to the robustness of a choice of t to the value of θ, as illustrated in Figure 1. Even ... HHTHHHTHHH (a) (b) Figure 1: The Bayesian approach to estimating the value of a latent variable, t, from observed data, w, chooses a value of t robust to uncertainty in θ. (a) P...

... finite-state automaton that only has two states. The automaton is set to initial state (q 0 ) at the top of a message. It makes a transition to state (q 1 ) when it encounters a quoted span of text. ... segmented into idea units. Thus, a span of text has a context within a message, defined by the sequence of text spans within that message, as well as a context from the large...
