13.6 Stochastic and mini-batch gradient descent
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.

Batch Gradient Descent
Stochastic Gradient Descent (SGD) updates parameters more frequently, using just one data point at a time. Mini-batch Gradient Descent strikes a balance, using subsets of the data, which can offer a middle ground in terms of computational efficiency and convergence stability.

Batch Gradient Descent in Python. The gradient descent algorithm… | by Uğur Özcan | Medium
March 17, 2022 - The gradient descent algorithm multiplies the gradient by a learning rate to determine the next point in the process of reaching a local minimum. In batch gradient descent, the error is calculated for each example in the training data set and the parameters are updated only after all training examples have been evaluated once.

When the batch size equals 1, we use stochastic gradient descent for optimization. For simplicity of implementation we picked a constant (albeit small) learning rate. In stochastic gradient descent, the model parameters are updated whenever an example is processed.

March 22, 2023 - To reduce a predefined loss function is the objective of gradient descent. It completes two main phases iteratively in order to accomplish this objective. First, determine the slope (gradient), which is the current point’s first-order derivative of the function. From the current location, move the calculated distance in the opposite direction of the slope up. ... In batch gradient descent, each step is determined by taking into account all the training data.

This function returns the mini-batches given the inputs and targets:
def iterate_minibatches(inputs, targets, batchsize, shuffle=False):
assert inputs.shape[0] == targets.shape[0]
if shuffle:
indices = np.arange(inputs.shape[0])
np.random.shuffle(indices)
for start_idx in range(0, inputs.shape[0] - batchsize + 1, batchsize):
if shuffle:
excerpt = indices[start_idx:start_idx + batchsize]
else:
excerpt = slice(start_idx, start_idx + batchsize)
yield inputs[excerpt], targets[excerpt]
and this tells you how to use that for training:
for n in xrange(n_epochs):
for batch in iterate_minibatches(X, Y, batch_size, shuffle=True):
x_batch, y_batch = batch
l_train, acc_train = f_train(x_batch, y_batch)
l_val, acc_val = f_val(Xt, Yt)
logging.info('epoch ' + str(n) + ' ,train_loss ' + str(l_train) + ' ,acc ' + str(acc_train) + ' ,val_loss ' + str(l_val) + ' ,acc ' + str(acc_val))
Obviously you need to define the f_train, f_val and other functions yourself given the optimisation library (e.g. Lasagne, Keras) you are using.

The following function returns (yields) mini-batches. It is based on the function provided by Ash, but correctly handles the last minibatch.
def iterate_minibatches(inputs, targets, batchsize, shuffle=False):
assert inputs.shape[0] == targets.shape[0]
if shuffle:
indices = np.arange(inputs.shape[0])
np.random.shuffle(indices)
for start_idx in range(0, inputs.shape[0], batchsize):
end_idx = min(start_idx + batchsize, inputs.shape[0])
if shuffle:
excerpt = indices[start_idx:end_idx]
else:
excerpt = slice(start_idx, end_idx)
yield inputs[excerpt], targets[excerpt]
