Machine Learning A Cost Function

    I call this a cost function rather than the cost function because one cost function does not fit all. Cost functions vary depending on the kind of data set or machine learning model. For the purposes of machine learning, cost functions become the algorithms that measure the performance of hypotheses. This equation comes […]

Machine Learning Three Algorithms

Linear regression, cost function and gradient descent sum up the first two weeks of Professor Ng’s Machine Learning class on Coursera. Since I am not aspiring to be a mathematician, I am going to refer to them as algorithms. Each of these algorithms has a particular place when designing a machine learning solution. Linear regression, […]
