In this tutorial, we’ll explain the difference between the cost, loss, and objective functions in machine learning. However, we should note that there’s no consensus on the exact definitions and that the three terms are often used as synonyms. 2. Loss Functions The loss function quantifies...
Summary We propose a dual frequency phase difference objective function specially designed for land data FWI. It is constructed by calculating the phase difference between two selected frequencies for both simulated and observed data respectively, then minimizing the difference between the phase differences...
Quantum computers provide a valuable resource to solve computational problems. The maximization of the objective function of a computational problem is a crucial problem in gate-model quantum computers. The objective function estimation is a high-cost pr
Electrical impedance tomography reconstruction through Simulated Annealing with incomplete evaluation of the objective function. The EIT reconstruction problem is approached as an optimization problem where the difference between a simulated impedance domain and the observed one is minimized. This optimization ...

In Eq. (6.50), p is arbitrary value for power in the line of the objective function. If a small value for p is selected, it cannot find all part of the Pareto front in the non-convex problem, and if a very big value is allocated to p it may lead to no results. Therefore, prop...
Kernel function kernel void fill(device uint8_t *array [[buffer(0)]], const device uint32_t &N [[buffer(1)]], const device uint8_t &value [[buffer(2)]], uint i [[thread_position_in_grid]]) { if (i < N) { array[i] = value; } } The Swift code is: func fill(pso:MT...

difference in the function values of two adjacent solutions. This calculation is continued with other objective functions. The overall crowding-distance value is calculated as the sum of individual distance values corresponding to each objective. Each objective function is normalized before calculating the...
