The latter is used to determine the best prediction model in data analysis. It is very important in machine learning, where it is used to minimize a cost function.
Gradient descent is also called “the deepest downward slope algorithm”. Conversely, a non-convex function is a function that has several local minima, and the gradient descent algorithm should not be used on these functions at the risk of getting stuck at the first minima encountered. It is an algorithm that is used, for example, in linear regression.Ī convex function is a function that looks like a beautiful valley with a global minimum in the center. To do this, it iteratively changes the parameters of the function in question. It is an algorithm to find the minimum of a convex function. The definition of gradient descent is rather simple. It is used to find the minimum value of a function more quickly. Gradient descent is an optimization algorithm. Among them, gradient descent is one of the most useful and popular.
We use different types of algorithms in machine learning. The more these algorithms are exposed to data, the more they learn to perform a task without specific instructions they learn by experience. The goal is, of course, to improve their predictions over time.Ĭonsequently, machine learning is largely based on the training of algorithms. To do this, the Data Scientist selects and trains algorithms to perform data analysis.
#Gradient descent algorithm software#
This means teaching software to perform a task or make predictions autonomously. Through machine learning, this is a matter of training algorithms to detect patterns in data analysis to perform a specific task better. These are called "patterns," i.e., recurring motifs. What is Gradient Descent?ĭata Science is about discovering complex patterns and behaviors in Big Data analysis.
If you are getting into machine learning, it is therefore imperative to understand the gradient descent algorithm in-depth. It is an extremely powerful optimization algorithm that can train linear regression, logistic regression, and neural network models. Gradient descent is one of the most important algorithms in all of machine learning and deep learning. Why is Gradient Descent so Important in Machine Learning?.
