, Gradient Descent in Machine Learning
 Gradient Descent is known as one of the most commonly used optimization algorithms to train
machine learning models by means of minimizing errors between actual and expected results.
 Further, gradient descent is also used to train Neural Networks.
 A gradient measures how much the output of a function changes if you change the inputs a little bit.
 In mathematical terminology, Optimization algorithm refers to the task of minimizing/maximizing
an objective function f(x) parameterized by x.
 Similarly, in machine learning, optimization is the task of minimizing the cost function parameterized
by the model's parameters.
 The main objective of gradient descent is to minimize the convex function using iteration of parameter updates.
 Once these machine learning models are optimized, these models can be used as powerful tools for
Artificial Intelligence and various computer science applications.
 Gradient descent finds the nearest minimum of a function(minimize the particular function),
Gradient ascent finds the nearest maximum.(maximize the particular function)

What is Gradient Descent or Steepest Descent?

 Gradient descent was initially discovered by "Augustin-Louis Cauchy" in mid of 18th century.
 Gradient Descent is defined as one of the most commonly used iterative optimization algorithms of
machine learning to train the machine learning and deep learning models.
 It helps in finding the local minimum of a function.



The best way to define the local minimum or local maximum of a function using gradient descent is as follows:

o If we move towards a negative gradient or away from the gradient of the function at the current point, it will

give the local minimum of that function.

o Whenever we move towards a positive gradient or towards the gradient of the function at the current point,

we will get the local maximum of that function.
