Sum of Functions¶
The sum of functions \(F(\theta)\) is a function that has the form of a sum:
For given set of the indices \(I = \{i_1, i_2, \ldots , i_m\}\), \(1 \leq ik < n\), \(k \in \{1, \ldots, m\}\), the value and the gradient of the sum of functions in the argument \(\theta\) has the format:
The set of the indices \(I\) is called a batch of indices.
