Machine Learning in Capital Markets : Part VII
This is the continuation of part VI of Machine Learning in Capital Markets. In the course of this work, a critical examination of the use of various learning methods in the analysis of financial market-specific data showed that machine learning methods are only conditionally suitable for successfully predicting share prices. A look at the results shows that there are sections of the stock … [Read more...]
Machine Learning in Capital Markets : Part VI
This is the continuation of part V of Machine Learning in Capital Markets. The determined values can be converted into a uniform interval by scaling. The interval can range from -100 to +100 units. It is only important that all values are scaled so that the relative size is not changed. In contrast to the RSI method, individual outliers are not eliminated, only the size of the individual … [Read more...]
