Effectiveness and limitations of parameter tuning in reducing biases of top-of-atmosphere radiation and clouds in MIROC version 5 [PDF]
Geoscientific Model Development, 2017 This study discusses how much of the biases in top-of-atmosphere (TOA) radiation and clouds can be removed by parameter tuning in the present-day simulation of a climate model in the Coupled Model Inter-comparison Project phase 5 (CMIP5) generation ...

Parameter Tuning for Local-Search-Based Matheuristic Methods
Complexity, 2017 Algorithms that aim to solve optimisation problems by combining heuristics and mathematical programming have attracted researchers’ attention. These methods, also known as matheuristics, have been shown to perform especially well for large, complex ...

High dimensional parameter tuning for event generators
European Physical Journal C: Particles and Fields, 2020 Monte Carlo Event Generators are important tools for the understanding of physics at particle colliders like the LHC. In order to best predict a wide variety of observables, the optimization of parameters in the Event Generators based on precision data ...

On Parameter Tuning for FAST TCP
IEEE Communications Letters, 2007 This paper studies the stability of FAST TCP using a continuous time model of a single-link single-source network. A sufficient condition on asymptotical stability of FAST TCP congestion window is obtained, which relates all the relevant parameters in FAST TCP and decouples the key parameter a from others.

Optimization of Neural Network-Based Self-Tuning PID Controllers for Second Order Mechanical Systems
Applied Sciences, 2021 The feasibility of a neural network method was discussed in terms of a self-tuning proportional–integral–derivative (PID) controller. The proposed method was configured with two neural networks to dramatically reduce the number of tuning attempts with a ...

Optimizing Performance of Hadoop with Parameter Tuning
ITM Web of Conferences, 2017 Optimizing Hadoop with the parameter tuning is an effective way to greatly improve the performance, but it usually costs too much time to identify the optimal parameters configuration because there are many parameters. Users are always blindly adjust too

A parameter-free learning automaton scheme
Frontiers in Neurorobotics, 2022 For a learning automaton, a proper configuration of the learning parameters is crucial. To ensure stable and reliable performance in stochastic environments, manual parameter tuning is necessary for existing LA schemes, but the tuning procedure is time ...

Calibrating the GAMIL3-1° climate model using a derivative-free optimization method [PDF]
Geoscientific Model DevelopmentParameterization in climate models often involves parameters that are poorly constrained by observations or theoretical understanding alone. Manual tuning by experts can be time-consuming, subjective, and prone to underestimating uncertainties. Automated
