Gradient Descent is a fundamental optimization algorithm in machine learning for minimizing the loss function and finding optimal model parameters. In this description, we cover the intuition behind the method, its extended versions like Stochastic and Mini-Batch Gradient Descent, and its critical role in delivering accurate regression and classification models. We encourage succeeding in this exciting field by supplementing your knowledge with resources such as:

1. Classical machine learning textbooks like “The Elements of Statistical Learning” or “Pattern Recognition and Machine Learning.”
2. Online courses by top universities and institutions including Coursera and edX.
3. Practical applications using popular libraries like TensorFlow or scikit-learn.

_Understanding the Gradient Descent Algorithm_
The primary objective of Gradient Descent (GD) is to minimize the cost function by using the negative gradient to iteratively update the model parameters. GD can be applied to both regression and classification problems, with multiple applications such as linear regression, logistic regression, and neural networks.

_Variations and Extensions_
Stochastic Gradient Descent (SGD) and Mini-Batch Gradient Descent (Mini-BDG) are popular extensions of GD. SGD uses a single training example at a time to update the weights, which can bring faster convergence and be less susceptible to getting stuck in local minima. Mini-BDG selects a batch of training examples at a time to average the gradients, which can tackle the high variance during SGD training.
