Water is an essential factor for the whole life and the human survival and, having an important role for both drinking as well economic sectors. Therefore, protecting this source against any pollution has become necessary (Witek and Jarosiewicz, 2009, Reza and Singh, 2010; Sojobi, 2016). In the last century, the availability and quality of surface or ground waters have been changing, mainly due to urbanization, industrialization etc.

We can use machine learning to predict labels on documents using a classification model. For both types of prediction questions, we develop a learner or model to describe the relationship between a target or outcome variable and our input features; what is different about a classification model is the nature of that outcome. A regression model predicts a numeric or continuous value. A classification model predicts a class label or group membership.

The user-defined tags make XML much more flexible for storing data than HTML.Indentation further facilitates reading but is not a necessary component of XML.

Create a .CSV file (or optionally, a MySQL database!) that includes all of the information described. You’re encouraged to use a “wide” structure similar to how the information appears above, so that you can practice tidying and transformations as described below.

The chess tournament text file is written in a format that is not legible in R. This file needs to be re-structured in order to find the average pre-tournament score.

Regular expressions, a powerful tool that enables you to search for complex patterns in text. - A regular expression is defined as a sequence of characters that represents a pattern that might or might not be present in any given string.
