Support Vector Machine (SVM) algorithm in python & machine learning is a simple yet powerful Supervised ML algorithm that can be used for both regression & classification models.
An algorithm, especially in mathematics, is a step-by-step procedure that can be used to solve computations or other mathematical problems. So, an algorithm can be thought of as a set of directions for solving mathematical computations and problems. This is the algorithm definition that is used...

You can implement the k-means algorithm inPython. First, you will need to define a function to calculate the Euclidean distance and then create some random data. # Function to calculate Euclidean distancedefeuclidean_distance(x1,x2):returnnp.sqrt(np.sum((x1-x2)**2))# Generate...
