http://neuralnetworksanddeeplearning.com/chap2.html Cost function measures the performance of a machine learning model for given data. Cost function quantifies the error between predicted and expected values and present that error in the form of a single real number. Depending on the problem, cost function can be formed in many different ways. The purpose … See more Let’s start with a model using the following formula: 1. ŷ= predicted value, 2. x= vector of data used for prediction or training 3. w= weight. Notice that … See more Mean absolute error is a regression metric that measures the average magnitude of errors in a group of predictions, without considering their directions. In other words, it’s a mean of absolute differences among predictions … See more There are many more regression metrics we can use as cost function for measuring the performance of models that try to solve regression problems (estimating the value). MAE and … See more Mean squared error is one of the most commonly used and earliest explained regression metrics. MSE represents the average squared difference between the predictions and … See more saban clothing morden
