Understanding Loss Functions to Maximize ML Model Performance

WebTwo cases are utilised to analyse and discuss the quality loss and hidden quality cost of a product using the cubic quality loss and quadratic quality loss functions. WebThe most popular loss function is the quadratic loss (or squared error, or L2 loss). When is a scalar, the quadratic loss is When is a vector, it is defined as where denotes the Euclidean norm. When the loss is quadratic, the expected value of the loss (the risk) is called Mean Squared Error (MSE). WebCross-entropy loss can be divided into two separate cost functions: one for y=1 and one for y=0. j(θ) = 1 m m ∑ i = 1Cost(hθ(x ( i)), y ( i)) Cost(hθ(x), y) = − log(hθ(x)) if y = 1 Cost(hθ(x), y) = − log(1 − hθ(x)) if y = 0 When we put them together we have: j(θ) = 1 m m ∑ i = 1 [y ( i) log(hθ(x ( i))) + (1 − y ( i))log(1 − hθ(x) ( i))] cscs the test company
