### In Probabilistic Graphical Model (written by Daphne Koller), what's the meaning of "parameter" in representation of the distribution?

I believe you are correct. When Koller mentions a parameter, it is in reference to the values needed to express the probability distribution. For example, the total number of parameters for a ...

### How to construct a reward function for a "wait and see" problem

In general, the term of art for this problem is "early classification." Early classification of time series has been extensively studied for minimizing class prediction delay in time-...
