what is the second description what is gradient descent algorithm where is the second description why does the second description conflict with the first why is a batch gradient gradient description conflicting each other why are two descriptions of batch gradient descent conflicting which algorithm uses batch gradient descent which algorithm is using batch gradient descent why are the two versions of the batch gradient descent algorithm contradicting each other? what is the difference between batch gradient descent and partial derivatives is batch gradient descent contradictory where is the description of gradient descent what is the difference between batch gradient descent and batch gradient descent why are two algorithms conflicting why is there no partial derivative in the first description which algorithm is used for gradient descent what is batch gradient descent algorithm what describes the batch gradient descent algorithm what is the difference between batch gradient descent algorithm and batch gradient descent algorithm why are the two descriptions of gradient descent conflicting each other?
