Trading-signal-using-the-candlestick-inverted-hammer
Brief study analyzing the potential of using the inverted hammer candlestick in trending stocks
Artificial-Neural-Network-to-predict-the-macroeconomics-scenario-to-buy-stocks-of-retail-sector
A model based in artificial neural network to predict buy and sell stocks of retail sector.
Influence-of-Lemmatization-and-Stemming-in-the-Word-Frequency-Text-Summarization
The aim of this study was to determine which method would be most efficient for generating summarization using the word frequency text. Three forms were analyzed: without any method, lemmatization and stemming. The rouge metrics were used as a score. The generation of summaries using the method of stemming was more suitable.
