WebThere are 2 main classes of algorithms used in this setting—those based on optimization and those based on Monte Carlo sampling. The folk wisdom is that sampling is … WebAn improved coarse alignment (ICA) algorithm is proposed in this paper with a focus on improving alignment accuracy of odometer-aided strapdown inertial navigation system (SINS) under variable velocity and variable acceleration condition. In the proposed algorithm, the outputs of inertial sensors and odometer in a sampling interval are linearized rather …
WebThe optimization of the objective function can be carried out either using an evolutionary algorithm , which can be rather slow, but has a good chance of finding a global optimum, or by using an approach based on gradient descent , which is much faster, but may need several different runs in order to converge to a good solution. WebDec 8, 2024 · Two commonly arising computational tasks in Bayesian learning are Optimization (Maximum A Posteriori estimation) and Sampling (from the posterior distribution). In the convex case these two problems are efficiently reducible to each other. Recent work [Ma et al., 2024] shows that in the non-convex case, sampling can …
WebIn this setting, where local properties determine global properties, optimization algorithms are unsurprisingly more efficient computationally than sampling algorithms. We instead … WebJun 14, 2024 · The bottom rule of finding the highest accuracy is that more the information you provide faster it finds the optimised parameters. Conclusion There are other optimisation techniques which might yield better results compared to these two, depending on the model and the data.
Webprofile your application. Identify what areas of code are taking how much time. See if you can use better data structures/ algorithms to make things faster. There is not much language specific optimization one can do - it is limited to using language constructs (learn from #1). The main benefit comes from #2 above.
