An Overview of Basic Gradient Descent Optimization Algorithms

Gradient Descent is a method for unconstrained mathematical optimization . It is a first-order iterative algorithm for minimizing a differentiable multivariate function.

  • Batch Gradient Descent computes gradient using entire training dataset for one update.
  • Stochastic Gradient Descent updates parameters with each random training example.
  • Mini-batch Gradient Descent balances accuracy and speed using small training batches.
