Is there a guaranteed order of operations within a systemd service?

Is there a precedence or order of operations for the performance of items in a systemd service unit configuration file? For example, ExecStartPre operations obviously happen before ExecStart. And multiple ExecStartPre operations are each executed to completion, serially and in order. Also, ExecCondition operations are defined to happen before ExecStartPre (and with a very specific…

Why we multiply probabilities with support to obtain Q-values in Distributional C51 algorithm?

In ‘Deep Reinforcement Learning Hands-On’ book and chapter about Distributional C51 algorithm I’m reading, that to obtain Q-values from the distribution I need to calculate the weighted sum of the normalized distribution and atom’s values. Why I have to multiply that distribution with support? How does it work and what happening there?
