Body

There are several optimization methods used in machine learning, including gradient descent, stochastic gradient descent, Newton’s method, and conjugate gradient.

Gradient Descent

Gradient descent is a popular optimization method used in machine learning. It is used to find the minimum of a function by taking small steps in the direction of the gradient. It is used to optimize the parameters of a model, such as weights and biases.

Stochastic Gradient Descent

Stochastic gradient descent is a variation of gradient descent. It is used to optimize a model by taking small steps in the direction of the gradient. It is used when the dataset is too large to be used in one go.

Newton’s Method

Newton’s method is another optimization method used in machine learning. It is used to find the minimum of a function by taking steps in the direction of the gradient. It is used to optimize the parameters of a model, such as weights and biases.

Conjugate Gradient

Conjugate gradient is an optimization method used in machine learning. It is used to find the minimum of a function by taking steps in the direction of the conjugate gradient. It is used to optimize the parameters of a model, such as weights and biases.
