Write an update equation for stochastic gradient descent based on a minibatch size of 2. The update equation chooses the next guess based on the Loss function, the last guess, and the current step size.
We are minimizing L(Θ) = Σ(Ln(Θi))T where i ranges over 1, 2, ..., 5 and n ranges over 1, 2, ..., 3.
