Machine learning techniques and data for stock market forecasting: A literature review

TL;DR: In this paper , a review of machine learning techniques applied for stock market prediction is presented, focusing on the stock markets investigated in the literature as well as the types of variables used as input in the machine learning methods used for predicting these markets.
Journal ArticleDOI

Global scenarios for significant water use reduction in thermal power plants based on cooling water demand estimation using satellite imagery

TL;DR: In this paper, the authors assess the water footprint of 13,863 thermal power plants units with a total active capacity of 4,182 GW worldwide and give an estimate of the current water demand for power production at four different levels.
Journal ArticleDOI

Classification of intraday S&P500 returns with a Random Forest

TL;DR: In this paper, the classification of the S&P500 open-to-close returns was interpreted as a four-class problem and four trading strategies based on a random forest classifier were compared to a buy-and-hold strategy.
Journal ArticleDOI

A combination of fuzzy similarity measures and fuzzy entropy measures for supervised feature selection

TL;DR: A filter feature ranking method for feature selection based on fuzzy similarity and entropy measures (FSAE), which is an adaptation of the idea used for the wrapper function by Luukka (2011) and has an additional scaling factor.
Journal ArticleDOI

A novel similarity classifier with multiple ideal vectors based on k-means clustering

TL;DR: A novel similarity classifier with multiple ideal vectors per class that are generated with k-means clustering in combination with the jump method is suggested, which achieves competitive results or even outperforms the k-nearest neighbour classifier, the Naive Bayes algorithm, decision trees, random forests and the standard similarity classifiers.
