The most common optimization algorithm used in machine learning is stochastic gradient descent. In this tutorial, you will discover how to implement stochastic gradient descent to optimize a linear regression a
In this step-by-step tutorial, you'll build a neural network from scratch as an introduction to the world of artificial intelligence (AI) in Python. You'll learn how to train your neural network and make accurate predictions based on a given dataset.
In this tutorial, you will discover how to implement the simple linear regression algorithm from scratch in Python. After completing this tutorial you will know: How to estimate statistical quantities from training data. How to estimate linear regression coefficients from data. How to make predictions...
On the other hand,Regressionanalysis is a statistical technique devoted to estimating the connection between one dependent and two or more independent variables. It can be used to simulate the long-term link between variables and evaluate the future outcome of the dependent variable. ForLinear Regres...
