A Hybrid Moth-Flame Optimization and Extreme Learning Machine Model for Financial Forecasting Abstract—In this work, a system for stock market prediction is proposed based on a hybrid moth-flame optimizer (MFO) and extreme learning machine (ELM). ELM is also a promising method for data regression and classification and has the advantage of fast training time, but it always requires a huge number of nodes in the hidden layer. The usage of a large number of nodes in the hidden layer increases the test/evaluation time of the net, and there is no grantee of optimality of the setting of weights and biases on the hidden layer. MFO is a recently proposed promising optimization algorithm that mimics the moving behavior of moths. MFO is exploited …show more content…

ELM is used as supervised learning method for SLFN method. ELM has high accuracy and fast prediction speed while solving numerous real-life problems [2], [6]. ELM randomly selects the input weights and hidden layer biases instead of fully tuning all the internal parameters such as gradient-based algorithms. ELM could analytically determine the output weights [2]. Due to random choosing of input weights and hidden layer biases, ELM needs more hidden neurons than gradient-based learning algorithms [7], [8]. The bio-inspired algorithms were used in optimizing ELM to overcome its drawbacks. In [7] differential evolution (DE) algorithm was applied to select input weights and biases to determine the output weights of ELM. DE-ELM achieved good generalization performance with a compact structure. In [9] DE-ELM was used for the classification of hyperspectral images, and it improved classification accuracy and computation time. In [10] Evolutionary ELM based on PSO algorithm is proposed, and PSO algorithm improved the performance of traditional ELM. In [11] a new method combined ELM with an improved PSO called is proposed to improve the convergence performance of ELM. In [12] an evolutionary approach for constituting extreme learning machine (ELM) ensembles is introduced to direct the selection of base learners and produced an optimal solution with ensemble size control. In [13] Genetic ensemble of
