As hinted at above, before scaling there were a number of predictor variables with ranges of different order of magnitudes, meaning that one or two of them could dominate in the context of an algorithm such as k-NN. The two main reasons for scaling your data are Your predictor variables ma...
In general, learning algorithms benefit from standardization of the data set. If some outliers are present in the set, robust scalers or transformers are more appropriate. The behaviors of the different scalers, transformers, and normalizers on a dataset containing marginal outliers is highlighted i...
it is entirely up to you to write the XML and to define a parsing function for it. The downside of using XML over CSV is that it adds some markup to the data, leaving a larger footprint. How large the extra footprint is depends on how you mark up your data. For example, if you...
Why Is Data Preprocessing Needed? Data preprocessingis a fundamental step in data analysis and machine learning. It’s an intricate process that sets the stage for the success of any data-driven endeavor. At its core, data preprocessing encompasses an array of techniques to transform raw, unrefin...
The amount of data collected from the 'Adilet' website is more than 500 thousand sentences, and the question-answer dataset from the 'Zqai' website consists of 740 questions and answers with a size of more than 18 thousand sentences. These datasets have a gigantic meaning in large language...
