implementaion of batch gradient descent in python using numpy and scipy

There are three variants of gradient descent, which differ in how much data we use to compute the gradient of the objective function. Depending on the amount of data, we make a trade-off between the accuracy of the parameter update and the time it takes to perform an update. Batch gradient descent, known also as Vanilla gradient descent, computes the gradient of the cost function with respect to the parameters \(\theta\) for the entire training dataset :

Ideally we want all mini-batches to have the same size - a parameter we call the batch size - or be as equally-sized as possible when $J$ does not divide $P$. Notice, a batch size of $1$ turns mini-batch gradient descent into stochastic gradient descent, whereas a batch size of $P$ turns it into the standard or batch gradient descent. The code cell below contains Python implementation of the mini-batch gradient descent algorithm based on the standard gradient descent algorithm we saw previously in Chapter 6, where it is now slightly adjusted to take in the total number of data points as well as the size of each mini-batch via the input variables num_pts and batch_size, respectively.

February 10, 2016 - This method is called “batch” gradient descent because we use the entire batch of points X to calculate each gradient, as opposed to stochastic gradient descent. which uses one point at a time.

The function’s interface consists of the X and Y sets of x-y pairs for some dataset, initial weight and bias hyperparameters, the number of epochs to run the algorithm for, and the learning rate gamma. It works by calculating the sum of all successive gradient descents using all the x-y data pairs supplied.
