Monkey patching is the term used to denote the modifications that are done to a class or a module during the runtime. This can only be done as Python supports changes in the behavior of the program while being executed.
Pandas is an open source python library which supports data structures for data based operations associated with data analyzing and data Manipulation. Pandas with its rich sets of features fits in every role of data operation,whether it be related to implementing different algorithms or for solving complex business problems. Pandas helps to deal with a number of files in performing certain operations on the data stored by files.
A dataframe refers to a two dimensional mutable data structure or data aligned in the tabular form with labeled axes(rows and column).
Regression is termed as supervised machine learning algorithm technique which is used to find the correlation between variables and help to predict the dependent variable(y) based upon the independent variable (x). It is mainly used for prediction, time series modeling, forecasting, and determining the causal-effect relationship between variables.
Scikit library is used in python to implement the regression and all machine learning algorithms.
There are two different types of regression algorithms in machine learning :
Linear Regression: Used when the variables are continuous and numeric in nature.
Logistic Regression: Used when the variables are continuous and categorical in nature.
Classification refers to a predictive modeling process where a class label is predicted for a given example of input data. It helps categorize the provided input into a label that other observations with similar features have. For example, it can be used for classifying a mail whether it is spam or not, or for checking whether users will churn or not based on their behavior.
These are some of the classification algorithms used in Machine Learning:
