Explore the three data science types—investigating, predicting, and optimizing—by examining data, forecasting outcomes, and solving regression and classification and optimization problems for maximum return.
learn to implement linear regression from scratch with numpy, using stochastic gradient descent to fit a line y = mx + b to x and y data, without libraries.
Discover how linear regression fits a best line to data by minimizing the cost function of squared errors. Use gradient descent to estimate the slope and intercept.
Explore how stochastic gradient descent optimizes linear regression by updating the slope and intercept to minimize the mean squared error, using learning rate and gradients.
Implement linear regression from scratch using stochastic gradient descent to minimize the mean squared error cost function, updating slope and intercept with learning rate over epochs.
In this course you will learn about linear regression which is a machine learning technique used in data science and you will learn on how to code linear regression from scratch in python using gradient descent .
Anybody who wants to enter into machine learning or data science can go through this course to get a basic understanding of machine learning .
In statistics, linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables). The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression.[1] This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable.[2]
In linear regression, the relationships are modeled using linear predictor functions whose unknown model parameters are estimated from the data. Such models are called linear models.[3] Most commonly, the conditional mean of the response given the values of the explanatory variables (or predictors) is assumed to be an affine function of those values; less commonly, the conditional median or some other quantile is used. Like all forms of regression analysis, linear regression focuses on the conditional probability distribution of the response given the values of the predictors, rather than on the joint probability distribution of all of these variables, which is the domain of multivariate analysis.
