WebNov 2, 2024 · To sum it up, momentum optimization is performed in two steps: 1. Calculating momentum vector at each iteration using the formula: where m is momentum vector, β is momentum, α is learning rate, θ is the set of machine learning parameters and ∇MSE is the partial derivative of the cost function ( Mean Squared Error in this case). 2. WebConvex Optimization and Machine Learning. Optimization is a crucial step in practical machine learning algorithms. In machine learning, an objective function and constraints are defined over a set of data to which the algorithms have to find an optimum solution. In machine learning, the problems are not necessarily convex. chu chem musical
