Machine Learning Part 1 Linear Regression

Machine Learning Part 1 Regression Chelsea Troy Linear regression, a statistical method first used in 1877, predicts the value of a dependent from an independent variable. essentially, it “fits” a linear line to most accurately match the relationship of the dependent and independent variable based upon a multitude of points provided to the model, similar to that of a scatter plot. The linear regression equation. the linear regression model aims to find the best fitting line through the data points. the equation of this line is given by: y=β0 β1 x1 β2 x2 … βn xn ϵ.

Learning Machine Learning Part 1 Linear Regression Cost Functions The basic idea is to fit a line through the data points in such a way that the differences between the observed values and the predicted values are minimized. the linear regression equation can be. The equation for simple linear regression is: y=\beta {0} \beta {1}x y =β0 β1x. where: y is the dependent variable. x is the independent variable. β0 is the intercept. β1 is the slope. multiple linear regression. this involves more than one independent variable and one dependent variable.

Linear regression is a foundational algorithm for machine learning and statistical modeling. traditionally, linear regression is the very first algorithm you’d learn when getting started with predictive modeling. while there are a lot more ml and deep learning algorithm in use today, linear regression has its place in several commercial data.

Learning rate. to choose a suitable learning rate, gradient descent has to be plotted and “debugged”. make a plot with number of iterations on the x axis. now plot the cost function, j (θ) over the number of iterations of gradient descent. if j (θ) ever increases, then you probably need to decrease α. Linear regression is a linear model, e.g. a model that assumes a linear relationship between the input variables (x) and the single output variable (y). more specifically, that y can be calculated from a linear combination of the input variables (x). when there is a single input variable (x), the method is referred to as simple linear regression.
