Linear regression example, using simdfied

Let’s test drive simdfied library with a linear regression example. We’ll use MLplaygroung.org, that uses simdfied for Machine Learning and can read csv or mat files. For example, a csv file representing house prices according to its square-foot and number of bedrooms: square foot, #bedrooms, price 2461.68 , 4 , 467883 1872, 4 , 385983 And […]
