Machine  Learning Algorithms

Machine Learning Techniques

Machine learning focuses on calculations, based on known property learned from the training data. Representation of information instance and purpose evaluate on these instances are part of all machine learning systems. Overview of the assets that the system will perform well on unseen data instances; the situations under which this can be specific are an input object of learning in the subfield of computational learning...

How to prepare dataset in arff and csv format

Machine learning algorithms are primarily designed to work with arrays of numbers. This is called tabular or structured data because it is how data looks in a spreadsheet, comprised of rows and columns. Weka has a specific computer science centric vocabulary when describing data: Instance: A row of data is called an instance, as in an instance or observation from the problem domain. Attribute: A...
